Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

[SCSI] ipr: Use PCI-E reset API for new ipr adapter Use a newly added PCI API to issue a PCI Fundamental reset (warm reset) to a new ipr PCI-E adapter. Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset).

A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

[SCSI] ipr: Support new device queueing model New ipr adapters support a new device queueing model in the adapter firmware. The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue. The new queueing model removes this complexity. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

scsi: Replace zero-length array with flexible-array member The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

This had a negative effect on performance for volume sets. The fix is to only set the flag for gscsi devices.

scsi: Replace zero-length array with flexible-array member The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

If the device is not present, then the scsi_device is torn down. As a part of scsi_device teardown a workqueue item will be scheduled and the lockups we see are because there are 250k workqueue items to be processed. Accoding to the specification of SIS-64 sas controller, max_channel should be decreased on SIS-64 adapters to 4. The patch fixes softlockup issue.

This patch adds a register definition which when written to with a predefined value will change the endianness back to what the driver expects. This patch also fixes two problems found during testing. First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only reserved one byte. The correct amount to reserve is 2 bytes.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

PCI: Rework config space blocking services pci_block_user_cfg_access was designed for the use case that a single context, the IPR driver, temporarily delays user space accesses to the config space via sysfs. This assumption became invalid by the time pci_dev_reset was added as locking instance. Today, if you run two loops in parallel that reset the same device via sysfs, you end up with a kernel BUG as pci_block_user_cfg_access detect the broken assumption. This reworks the pci_block_user_cfg_access to a sleeping service pci_cfg_access_lock and an atomic-compatible variant called pci_cfg_access_trylock. The former not only blocks user space access as before but also waits if access was already locked. The latter service just returns false in this case, allowing the caller to resolve the conflict instead of raising a BUG. Adaptions of the ipr driver were originally written by Brian King.

Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable.

ipr: wait for aborted command responses Fixes a race condition in abort handling that was injected when multiple interrupt support was added. When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself. With multiple interrupts, these responses generally come back on different interrupts, so we need to ensure the abort thread waits until the aborted command is complete so we don't perform a double completion. This race condition was being hit frequently in environments which were triggering command timeouts, which was resulting in a double completion causing a kernel oops.

The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue.
