[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: optimize receive restart When the driver handles multiple packets per NAPI poll, it is better to reload the receive ring, then tell the hardware. Otherwise, under packet storm with flow control, the driver/hardware will degrade down to one packet getting through per pause-exchange.

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload.

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

sky2: EC-U performance and jumbo support The Yukon EC Ultra chips have transmit settings for store and forward and PCI buffering. By setting these appropriately, normal performance goes from 750Mbytes/sec to 940Mbytes/sec (non-jumbo). It is also possible to do Jumbo mode, but it means turning off TSO and checksum offload so the performance gets worse. There isn't enough buffering for checksum offload to work.

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[VLAN]: Avoid a 4-order allocation. This patch splits the vlan_group struct into a multi-allocated struct. On x86_64, the size of the original struct is a little more than 32KB, causing a 4-order allocation, which is prune to problems caused by buddy-system external fragmentation conditions. I couldn't just use vmalloc() because vfree() cannot be called in the softirq context of the RCU callback.

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

This causes hangs, and IP will see lots of garbage packets. There is even the potential for data corruption if a later arriving packet DMA's into freed memory. It looks like a hardware bug because status arrives for a packet but no data is there. Until this bug is worked out, block the user from bringing up both ports at once.

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

By setting these appropriately, normal performance goes from 750Mbytes/sec to 940Mbytes/sec (non-jumbo).

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[NET] gso: Add skb_is_gso This patch adds the wrapper function skb_is_gso which can be used instead of directly testing skb_shinfo(skb)->gso_size. This makes things a little nicer and allows us to change the primary key for indicating whether an skb is GSO (if we ever want to do that).

[NET]: Merge TSO/UFO fields in sk_buff Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not going to scale if we add any more segmentation methods (e.g., DCCP). So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

This maybe the cause of the lockup under load. http://bugzilla.kernel.org/show_bug.cgi?id=6839 Patch against netdev-2.6 git tree Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

sky2: flow control setting fixes The result of flow control negotiation should not limit the next negotiatition. If board is plugged into an old half duplex 10Mbit port, without pause, then replugged into a gigabit port, it should negotiate what is desired, not inherit that last negotiation.

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

sky2: flow control negotiation for Yukon-FE The Yukon-FE chip doesn't do gigabit and has a differen PHY internally.

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: fragmented receive for large MTU Use hardware support for chained receive to break up large frames into multiple pages. This avoids having to do a mult-page allocation that can fail on a busy system due to fragmented memory. For normal size MTU, this code behaves the same.

[PATCH] sky2: fix FIFO DMA alignment problems The Yukon2 chip FIFO has a problem recovering from a pause frame if the receive buffer is not aligned. The workaround is to just leave receive buffer at original alignment, which will make IP header unaligned. Rework receive logic for clarity. Need to ignore receive overrun interrupts (or mac hangs). These fixes make the sky2 driver generally usable. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

Use this as a detection mechanism to turn off Rx checksumming. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: revert pci express extensions The pci express error handling extensions don't work unless PCI access is via mmconfig. Otherwise, all accesses to pci config registers greater than 256 fail. Since the sky2 driver has other ways of getting to PCI config space, it works around this short coming, but the pci_find_ext_capablity doesn't work. This backs out commit 91aeb3edbcf4e6ed72d138ac8c22fd68e6d717c3 Go back to hardcoding, since we know where the error registers are anyway.

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload.

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: netpoll on dual port cards The sky2 driver uses a single NAPI poll routine for both ports on dual ported cards (because there is a single IRQ and status ring). Netpoll makes assumptions about the relationship between network device and NAPI that aren't correct on the second port, this will cause the port to never clear work. Most systems, just have single port, so not a big issue. The easy fix is just make the second port, not netpoll capable.

[PATCH] sky2: allow dual port usage If both ports are receiving on the SysKonnect dual port cards, then it appears the bus interface unit can give an interrupt status for frame before DMA has completed. This leads to bogus frames and general confusion. This is why receive checksumming is also messed up on dual port cards. A workaround for the out of order receive problem is to eliminating split transactions on PCI-X. This version is based of the current linux-2.6.git including earlier patch to disable dual ports.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: new experimental Marvell Yukon2 driver New driver for the Marvell Yukon2 Gigabit Ethernet chipset. This driver is based on the skge driver, but using the logic from the SysKonnect version of the sk98lin driver. It should support all the Yukon2 chipsets that are available in many current Intel and AMD motherboards. The driver does support ethtool, tx and rx checksum, and tcp segmentation offload. But it has only been tested for a short while and is known to stop receiving under heavy load. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

[PATCH] sky2: driver update. Here is revised patch against netdev sky2 branch. It includes whitespace fixes, all the changes from the previous review as well as some optimizations and timing fixes to solve some of the hangs. The stall problem is better but not perfect. It appears that under stress the chip can't keep up with the bus and sends a pause frame, then hangs. This version is for testing, and hopefully other eyes might see the root cause of the problem. I don't want to reinvent the ugly watchdog code in the syskonnect version of sk98lin. If you read it you will see, the original driver writer and the hardware developer obviously didn't understand each other. Dual port support is included, but not tested yet. It did require small change to NAPI since both ports share same IRQ. Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
