2011-08-22drm/radeon/alpha: Add Alpha support to Radeon DRM codeJay Estabrook1-0/+23
Alpha needs to have available the system bus address for the Radeon's local memory, so that it can be used in ttm_bo_vm_fault(), when building the PTEs for accessing that VRAM. So, we make bus.addr hold the ioremap() return, and then we can modify bus.base appropriately for use during page fault processing.

2011-08-20sparc: Allow handling signals when stack is corrupted.David S. Miller8-233/+468
If we can't push the pending register windows onto the user's stack, we disallow signal delivery even if the signal would be delivered on a valid seperate signal stack. Add a register window save area in the signal frame, and store any unsavable windows there. On sigreturn, if any windows are still queued up in the signal frame, try to push them back onto the stack and if that fails we kill the process immediately. This allows the debug/tst-longjmp_chk2 glibc test case to pass. Signed-off-by: David S. Miller <[email protected]>

2011-08-20ALSA: hda - Don't spew too many ELD errorsTakashi Iwai1-12/+19
Currently HD-audio driver shows the all error ELD byte as an error in the kernel message. This is annoying when the video driver doesn't set the correct ELD from the beginning. e.g. radeon sends a zero-byte data, but we still check ELD with the fixed 128 byte as a workaround for some broken devices, it spews 128-times errors. For avoiding this, the driver aborts reading when the first byte is invalid. In such a case, the whole data is certainly invalid. Signed-off-by: Takashi Iwai <[email protected]>

2011-08-19ext4: flush any pending end_io requests before DIO reads w/dioread_nolockJiaying Zhang1-2/+7
There is a race between ext4 buffer write and direct_IO read with dioread_nolock mount option enabled. The problem is that we clear PageWriteback flag during end_io time but will do uninitialized-to-initialized extent conversion later with dioread_nolock. If an O_direct read request comes in during this period, ext4 will return zero instead of the recently written data. This patch checks whether there are any pending uninitialized-to-initialized extent conversion requests before doing O_direct read to close the race. Note that this is just a bandaid fix. The fundamental issue is that we clear PageWriteback flag before we really complete an IO, which is problem-prone. To fix the fundamental issue, we may need to implement an extent tree cache that we can use to look up pending to-be-converted extents.

2011-08-19drm/i915: set GFX_MODE to pre-Ivybridge default value even on IvybridgeJesse Barnes2-0/+8
Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that MI_FLUSH would flush the TLBs in addition to the rest of the caches indicated in the MI_FLUSH command. However starting with Ivybridge, the register defaults to 0x2800 out of reset, meaning that to invalidate the TLB we need to use PIPE_CONTROL. Since we're not doing that yet, go back to the old default so things work. v2: don't forget to actually *clear* the new bit Reviewed-by: Eric Anholt <[email protected]> Reviewed-by: Chris Wilson <[email protected]> Tested-by: Kenneth Graunke <[email protected]> Signed-off-by: Jesse Barnes <[email protected]>

2011-08-19squeeze max-pause area and drop pass-good areaWu Fengguang2-24/+2
Revert the pass-good area introduced in ffd1f609ab10 ("writeback: introduce max-pause and pass-good dirty limits") and make the max-pause area smaller and safe. This fixes ~30% performance regression in the ext3 data=writeback fio_mmap_randwrite_64k/fio_mmap_randrw_64k test cases, where there are 12 JBOD disks, on each disk runs 8 concurrent tasks doing reads+writes. Using deadline scheduler also has a regression, but not that big as CFQ, so this suggests we have some write starvation. The test logs show that - the disks are sometimes under utilized - global dirty pages sometimes rush high to the pass-good area for several hundred seconds, while in the mean time some bdi dirty pages drop to very low value (bdi_dirty << bdi_thresh). Then suddenly the global dirty pages dropped under global dirty threshold and bdi_dirty rush very high (for example, 2 times higher than bdi_thresh). During which time balance_dirty_pages() is not called at all. So the problems are 1) The random writes progress so slow that they break the assumption of the max-pause logic that "8 pages per 200ms is typically more than enough to curb heavy dirtiers". 2) The max-pause logic ignored task_bdi_thresh and thus opens the possibility for some bdi's to over dirty pages, leading to (bdi_dirty >> bdi_thresh) and then (bdi_thresh >> bdi_dirty) for others. 3) The higher max-pause/pass-good thresholds somehow leads to the bad swing of dirty pages. The fix is to allow the task to slightly dirty over task_bdi_thresh, but no way to exceed bdi_dirty and/or global dirty_thresh. Tests show that it fixed the JBOD regression completely (both behavior and performance), while still being able to cut down large pause times in balance_dirty_pages() for single-disk cases.

2011-08-19ALSA: usb-audio - Fix missing mixer dB informationTakashi Iwai1-1/+2
The recent fix for testing dB range at the mixer creation time seems to cause regressions in some devices. In such devices, reading the dB info at probing time gives an error, thus both dBmin and dBmax are still zero, and TLV flag isn't set although the later read of dB info succeeds. This patch adds a workaround for such a case by assuming that the later read will succeed. In future, a similar test should be performed in a case where a wrong dB range is seen even in the later read. Signed-off-by: Takashi Iwai <[email protected]> Cc: <[email protected]>

Currently, error handling code in this function calls the function sata_dwc_port_stop, but this function has essentially no effect if hsdevp has not been stored in ap, which is the case throughout this function. The only effect is to print a debugging message including ap->print_id. The code is rewritten to not call sata_dwc_port_stop, but instead to jump to a local label that prints the original error message and the print_id information. In the case where hsdevp has been already allocated (but not yet stored in ap), this value is freed as well.
