| 152e1d5 | Colin Cross | 02 September 2010, 23:24:07 UTC | PM: Prevent waiting forever on asynchronous resume after failing suspend During suspend, the power.completion is expected to be set when a device has not yet started suspending. Set it on init to fix a corner case where a device is resumed when its parent has never suspended. Consider three drivers, A, B, and C. The parent of A is C, and C has async_suspend set. On boot, C->power.completion is initialized to 0. During the first suspend: suspend_devices_and_enter(...) dpm_resume(...) device_suspend(A) device_suspend(B) returns error, aborts suspend dpm_resume_end(...) dpm_resume(...) device_resume(A) dpm_wait(A->parent == C) wait_for_completion(C->power.completion) The wait_for_completion will never complete, because complete_all(C->power.completion) will only be called from device_suspend(C) or device_resume(C), neither of which is called if suspend is aborted before C. After a successful suspend->resume cycle, where B doesn't abort suspend, C->power.completion is left in the completed state by the call to device_resume(C), and the same call path will work if B aborts suspend.

| 9f82d23 | Daniel Vetter | 30 August 2010, 19:25:23 UTC | drm/i915: overlay on gen2 can't address above 1G So set the coherent dma mask accordingly. This dma mask is only used for physical objects, so it won't really matter allocation-wise. Now this never really surfaced because sane 32bit kernels only have 1G of lowmem. But some eager testers (distros?) still carry around the patch to adjust lowmem via a kconfig option. And the kernel seems to favour high allocations on boot-up, hence the overlay blowing up reliably. Because the patch is tiny and nicely shows how broken gen2 is it's imho worth to merge despite the fact that mucking around with the lowmem/ highmem division is (no longer) supported.

| e58f637 | Chris Wilson | 20 August 2010, 08:13:36 UTC | drm/kms: Add a module parameter to disable polling Polling for a VGA device on an old system can be quite expensive, causing latencies on the order of 600ms. As we hold the mode mutex for this time and also need the same mutex to move the cursor, we trigger a user-visible stall. The real solution would involve improving the granulatity of the locking and so perhaps performing some of the probing not under the lock or some other updates can be done under different locks. Also reducing the cost of probing for a non-existent monitor would be worthwhile. However, exposing a parameter to disable polling is a simple workaround in the meantime. In order to accommodate users turning polling on and off at runtime, the polling is potentially re-enabled on every probe. This is coupled to the user calling xrandr, which seems to be a vaild time to reset the polling timeout since the information on the connection has just been updated. (The presumption being that all connections are probed in a single xrandr pass, which is currently valid.)

| 0791971 | Thadeu Lima de Souza Cascardo | 28 August 2010, 06:06:29 UTC | usb: allow drivers to use allocated bandwidth until unbound When using the remove sysfs file, the device configuration is set to -1 (unconfigured). This eventually unbind drivers with the bandwidth_mutex held. Some drivers may call functions that hold said mutex, like usb_reset_device. This is the case for rtl8187, for example. This will lead to the same process holding the mutex twice, which deadlocks. Besides, according to Alan Stern: "The deadlock problem probably could be handled somehow, but there's a separate issue: Until the usb_disable_device call finishes unbinding the drivers, the drivers are free to continue using their allocated bandwidth. We musn't change the bandwidth allocations until after the unbinding is done. So this patch is indeed necessary." Unbinding the driver before holding the bandwidth_mutex solves the problem. If any operation after that fails, drivers are not bound again. But that would be a problem anyway that the user may solve resetting the device configuration to one that works, just like he would need to do in most other failure cases.

| c7aa8f4 | Dirk De Schepper | 24 August 2010, 19:38:35 UTC | USB: option: fix incorrect novatel entries Unfortunately some of the hardware PID belonging to auto-install CDROM (AICD) of Novatel modems found their way into the option module. This causes the AICD to be treated as a modem in stead of a disk. Since the modem ports do not appear until after the AICD is ejected, this essentially disables the modem. After a couple of minutes the AICD should auto-eject, but it is just too long a wait. The frequency of the failure seems to depend on both the hardware and the linux distribution. Here is a patch that fixes this up, and also adds a couple of new PID, offering some explanations and removing some incomplete and unnecessary comments.

| 6eb68d6 | Nathael Pajani | 02 September 2010, 14:06:16 UTC | tty: fix tty_line must not be equal to number of allocated tty pointers in tty driver I found a bug "by chance" in drivers/char/tty_io.c I mean "by chance" because I was just reading the code of the tty_find_polling_driver() to make a new tty_find_by_name() function. In tty_find_polling_driver() the driver actually test "tty_line <= p->num" while num refers to the number of struct tty_struct pointers allocated for the p->ttys (p is a tty_driver), and tty_line is scanned in a tty name, which can be for example ttyS2. Then tty_line equals 2. And if p->num is 2, we have only p->ttys[0] and p->ttys[1], but no p->ttys[2]. This is actually unharmful, for tty_find_polling_driver() is used only in drivers/serial/kgdboc.c, and there's a test over there to find a console with a matching index, which will never happen.

| 9fc2b2d | Francisco Jerez | 22 August 2010, 15:37:24 UTC | vt: Fix console corruption on driver hand-over. After 02f0777a0d6560eb995aade34a1b82f95c0452da "vc_origin" is no longer reset to the screen buffer before calling the con_init() hook of the new console driver. If the old driver wasn't using a fixed scanout buffer (e.g. the case of vgacon) "vc_origin" may be a pointer to a VRAM location, and its contents aren't guaranteed to be preserved after calling con_deinit() on the old driver and con_init() on the new driver, i.e. the subsequent console resize may fill the framebuffer with garbage. It can be reproduced in the transition from vgacon to the nouveau framebuffer driver: in that case the legacy VGA aperture "vc_origin" points to becomes unreadable after fbcon_init(). This patch reverts the mentioned commit. To avoid the problem it intended to fix, stop using "vc_scr_end" in vc_do_resize() to calculate how many rows we have to copy (actually the code looks simpler this way without the help of "vc_scr_end").

| 9af2546 | Tao Ma | 30 August 2010, 02:44:03 UTC | xfs: Make fiemap work with sparse files In xfs_vn_fiemap, we set bvm_count to fi_extent_max + 1 and want to return fi_extent_max extents, but actually it won't work for a sparse file. The reason is that in xfs_getbmap we will calculate holes and set it in 'out', while out is malloced by bmv_count(fi_extent_max+1) which didn't consider holes. So in the worst case, if 'out' vector looks like [hole, extent, hole, extent, hole, ... hole, extent, hole], we will only return half of fi_extent_max extents. This patch add a new parameter BMV_IF_NO_HOLES for bvm_iflags. So with this flags, we don't use our 'out' in xfs_getbmap for a hole. The solution is a bit ugly by just don't increasing index of 'out' vector. I felt that it is not easy to skip it at the very beginning since we have the complicated check and some function like xfs_getbmapx_fix_eof_hole to adjust 'out'.
