From 5d5ff44fe6775ccb922fd1f7d478b2ba9ca95068 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 3 Jun 2006 13:21:13 +0200 Subject: [SCSI] fix up request buffer reference in various scsi drivers Various scsi drivers use scsi_cmnd.buffer and scsi_cmnd.bufflen in their queuecommand functions. Those fields are internal storage for the midlayer only and are used to restore the original payload after request_buffer and request_bufflen have been overwritten for EH. Using the buffer and bufflen fields means they do very broken things in error handling.

Miller" Date: Tue, 20 Jun 2006 01:21:29 -0700 Subject: [SPARC]: Kill __irq_itoa(). This ugly hack was long overdue to die. It was a way to print out Sparc interrupts in a more freindly format, since IRQ numbers were arbitrary opaque 32-bit integers which vectored into PIL levels. These 32-bit integers were not necessarily in the 0-->NR_IRQS range, but the PILs they vectored to were. The idea now is that we will increase NR_IRQS a little bit and use a virtual<-->real IRQ number mapping scheme similar to PowerPC. That makes this IRQ printing hack irrelevant, and furthermore only a handful of drivers actually used __irq_itoa() making it even less useful. Signed-off-by: David S.

However it turns out that even though they don't actually switch power, they do ignore all events on a port until told to turn on the power! This problem has been reported by several users. This revised patch (as672b) makes the hub driver always try to turn on port power to all hubs, regardless of what the hub descriptor says. It also adds a comment explaining the need for this.

The scsi layer is now much more likely to pass down scatterlists instead of plain buffers. So you have to make sure that they're handled correctly. In one of the changes along the way, usbat_write_block and friends stopped obeying the srb->use_sg flag. Anyway, with the appended patch, and the one I'm putting in the next email, it all seems to work for the HP cd4e. Of course, someone's going to have to test it with the flash drives as well.... This patch teaches the usbat_{read,write}_block functions to obey the use_sg flag in the scsi-request.

Now that Peter Chubb's patch has simplified the detection of 99% of the HP CD writers out there, we have a much smaller range of hardware to work with on the shared device ID, so it should be possible to try some of the previous probe options again: we just need to find another tester with a USBAT2-based HP CD writer. This patch hardcodes the flash detection until someone comes along with one of these obscure CD drives. Note that these devices are extremely rare, so even if we can't ever find a decent probe method, at least we will be supporting almost all of the USBAT-based hardware out there.

When an HID event is then sent up to the input layer, it may then be discarded as irrelevant because the wrong capability bit is set. Further, the quirks for the Apple Mighty Mouse are not quite right: the horizontal scrolling needs its axis reversed, and the left and center buttons are transposed. Also, the mouse is labeled in the kernel with its earlier name (I think) of Apple PowerMouse. Steps to reproduce problem: Plug in an Apple Mighty Mouse. Note that horizontal scrolling doesn't work at all, and in fact doesn't generate any input events on /dev/input/eventN. Note also that pushing the middle button performs the right button action, and vice versa. Once you have the horizontal scrolling working, note that it is backward WRT both to vertical scrolling and to common sense. This patch maybe should be broken up, as it does address two problems. The transposed code in hidinput_configure_usage() probably creates bugs beyond just the Mighty Mouse. The rest of the patch renames POWERMOUSE to MIGHTYMOUSE everywhere (which I *believe* is correct), fixes the MIGHTYMOUSE quirk to swap the center and right mouse buttons, and adds a new quirk HID_QUIRK_INVERT_HWHEEL also assigned to the MIGHTYMOUSE with code in hidinput_hid_event() to implement it.

The next TD on each of the non-moving queues is modified to generate an interrupt on completion, so that FSBR can be re-enabled as soon as the hardware starts to make some progress.

The USB spec does not specify a strict limit on the size of an entire control transfer. It does, however, state that the data stage "follows the same protocol rules as bulk transfers." (USB 2, 8.5.3) The level of support for large control transfers in real host controllers varies, but it's important to support at least 4K transfers. Windows enforces a maximum control transfer size of 4K, so there exists some hardware that requires a full 4096 byte data stage. Without this patch, we fall short of that by 8 bytes on architectures with a 4K page size, and it becomes impossible to support such hardware with a user-space driver. Since any limit placed on control transfers by usbfs would be arbitrary, this patch replaces the PAGE_SIZE limit with the same arbitrary limit used by bulk transfers.

Because ISO queues aren't controlled by queue headers, they can't be unlinked. Only individual URBs can. So whenever multiple ISO URBs are dequeued, it's necessary to make sure the hardware is done with each one. We can't assume that dequeuing the first URB will suffice to unlink the entire queue.

The new scheduler is selected by a config option, marked as EXPERIMENTAL so it can be tested (and more broadly reviewed) for a while until it seems safe to remove the original scheduler.

Drivers are notified about impending and completed resets through two new methods in the usb_driver structure. The patch modifieds the usbfs ioctl code to make it use the new routine instead of usb_reset_device().

It's not needed because it conveys exactly the same information as the generic HCD_FLAG_HW_ACCESSIBLE bit. In its place goes a new flag recording whether the controller is dead. The new code allows a complete device reset to resurrect a dead controller (although usbcore doesn't yet implement such a facility).

FSBR puts a noticeable load on a computer's PCI bus, so it should be disabled as soon as possible when it isn't in use. The patch leaves it running for only 10 ms after the last URB stops using it, on the theory that this should be long enough for a driver to submit another URB if it wants keep FSBR going.

This happened because I forgot to update the size when status packets began to be printed. The rest is: - Comments updates - Allow snooping with pkmap on x86_64, which is cache-coherent - Enlarge event buffers (certainly we can have a couple of pages) - Add event counter First touch upon usbmon for 2.6.18.

The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

It also causes performance problems when one does a lot of async io and then proceeds to sync it. Part of the io will go out as async, and the other part as sync. This causes a disconnect between the previously submitted io and the synced io. For io schedulers such as CFQ, this will cause us lost merges and suboptimal behaviour in scheduling. Remove PF_SYNCWRITE completely from the fsync/msync paths, and let the O_DIRECT path just directly indicate that the writes are sync by using WRITE_SYNC instead.
