Raw Normal View History

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. Let it rip!

[PATCH] UHCI: improve debugging code This patch (as626) makes some improvements to the debugging code in uhci-hcd. The main change is that now the code won't get compiled if CONFIG_USB_DEBUG isn't set. But there are other changes too, like adding a missing .owner field and printing a debugging dump if the controller dies.

[PATCH] UHCI: use dummy TDs This patch (as624) fixes a hardware race in uhci-hcd by adding a dummy TD to the end of each endpoint's queue. Without the dummy the host controller will effectively turn off the queue when it reaches the end, which happens asynchronously. This leads to a potential problem when new transfer descriptors are added to the end of the queue; they may never get used. With a dummy TD present the controller never turns off the queue; instead it just stops at the dummy and leaves the queue on but inactive. When new TDs are added to the end of the queue, the first new one gets written over the dummy. Thus there's never any question about whether the queue is running or needs to be restarted.

UHCI: improved debugging checks for the frame list This patch (as768) improves the debugging checks for the uhci-hcd frame list. The number of entries displayed is limited to 10, and the driver now checks for the correct Skeleton QH link value at the end of each chain of Isochronous TDs.

UHCI: Eliminate asynchronous skeleton Queue Headers This patch (as856) attempts to improve the performance of uhci-hcd by removing the asynchronous skeleton Queue Headers. They don't contain any useful information but the controller has to read through them at least once every millisecond, incurring a non-zero DMA overhead. Now all the asynchronous queues are combined, along with the period-1 interrupt queue, into a single list with a single skeleton QH. The start of the low-speed control, full-speed control, and bulk sublists is determined by linear search. Since there should rarely be more than a couple of QHs in the list, the searches should incur a much smaller total load than keeping the skeleton QHs.

It turns out that some systems really do need to have a terminating skeleton QH present whenever FSBR is on.

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.

[PATCH] USB UHCI: Add root hub states This patch starts making some serious changes to the UHCI driver. There's a set of private states for the root hub, and the internal routines for suspending and resuming work completely differently, with transitions based on the new states. Now the driver distinguishes between a privately auto-stopped state and a publicly suspended state, and it will properly suspend controllers with broken resume-detect interrupts instead of resetting them.

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. Let it rip!

UHCI: Eliminate asynchronous skeleton Queue Headers This patch (as856) attempts to improve the performance of uhci-hcd by removing the asynchronous skeleton Queue Headers. They don't contain any useful information but the controller has to read through them at least once every millisecond, incurring a non-zero DMA overhead. Now all the asynchronous queues are combined, along with the period-1 interrupt queue, into a single list with a single skeleton QH. The start of the low-speed control, full-speed control, and bulk sublists is determined by linear search. Since there should rarely be more than a couple of QHs in the list, the searches should incur a much smaller total load than keeping the skeleton QHs.

[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_private The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

It turns out that some systems really do need to have a terminating skeleton QH present whenever FSBR is on.
