sync can currently take a really long time if a concurrent writer is extending a file. The problem is that the dirty pages on the address space grow in the same direction as write_cache_pages scans, so if the writer keeps ahead of writeback, the writeback will not terminate until the writer stops adding dirty pages. For a data integrity sync, we only need to write the pages dirty at the time we start the writeback, so we can stop scanning once we get to the page that was at the end of the file at the time the scan started. This will prevent operations like copying a large file preventing sync from completing as it will not write back pages that were dirtied after the sync was started. This does not impact the existing integrity guarantees, as any dirty page (old or new) within the EOF range at the start of the scan will still be captured. This patch will not prevent sync from blocking on large writes into holes. That requires more complex intervention while this patch only addresses the common append-case of this sync holdoff.

Now that the background flush code has been fixed, we shouldn't need to silently multiply the wbc->nr_to_write to get good writeback. Remove that code. Signed-off-by:

Dave Chinner authored
If a filesystem writes more than one page in ->writepage, write_cache_pages fails to notice this and continues to attempt writeback when wbc->nr_to_write has gone negative - this trace was captured from XFS: wbc_writeback_start: towrt=1024 wbc_writepage: towrt=1024 wbc_writepage: towrt=0 wbc_writepage: towrt=-1 wbc_writepage: towrt=-5 wbc_writepage: towrt=-21 wbc_writepage: towrt=-85 This has adverse effects on filesystem writeback behaviour. write_cache_pages() needs to terminate after a certain number of pages are written, not after a certain number of calls to ->writepage are made. This is a regression introduced by 17bc6c30 ("vfs: Add no_nrwrite_index_update writeback control flag"), but cannot be reverted directly due to subsequent bug fixes that have gone in on top of it.

Commit 55929332 "drivers: Push down BKL into various drivers" introduced a regression in hp_sdc_rtc, caused by a missing change of the .unlocked_ioctl pointer to the newly introduced function. Fixes: drivers/input/misc/hp_sdc_rtc.c:681: warning: initialization from incompatible pointer type drivers/input/misc/hp_sdc_rtc.c:665: warning: ‘hp_sdc_rtc_unlocked_ioctl’ defined but not used Reported-by:

So when we added output polling, we'd suddenly use this code more often, and the fact that it always takes over crtc2 and messes with it during probing isn't what we really want to be happening. A more complete fix would to change it to use whatever crtc was free at the time, but for now lets stay simple and just don't poll if crtc2 is already in use. Although a more correct fix was found I suspect we should do this as well, until we get a chance to readdres the tv out polling issues. Reported-by:

We really don't want to be polling tv-out but since we weren't forcing the i2c lines to invalid (tv-out has no DDC), we were adding tv connectors to the polling setup and this was causing blinking on secondary displays. This fixes the regression Torsten reported. Reported-by:

This fixes FDO bug #28375, it's kind of regression, so quite important to have it for .35. V2: Fix on RV770+ as well. All other chipsets have only one clock mode per state. V3: I'm out of luck today. Grepped for voltage in r*.c and missed evergreen. agd5f: rebased Signed-off-by:

The vddc value in the power tables is not an actual voltage like on discrete r6xx/r7xx/evergreen systems, but instead has a symbolic meaning (e.g., NONE, LOW, HIGH, etc.). See atombios.h Most RS780/RS880 vbioses don't have a SetVoltage table anyway, so it shouldn't be doing anything to the hardware at the moment. I need to figure out how voltage is supposed to work on the newer IGPs; until then, disable it. Signed-off-by:

This adds an additional profile, mid, to the pm profile code which takes the place of the old low profile. The default behavior remains the same, e.g., auto profile now selects between mid and high profiles based on power source, however, you can now manually force the low profile which was previously only available as a dpms off state. Enabling the low profile when the displays are on has been known to cause display corruption in some cases. Signed-off-by:

- don't rest the power state in pm_init() We already boot up to the default power state. Note this patch relies on: drm/radeon/kms/pm: patch default power state with default clocks/voltages on r6xx+ To make sure the default power state matches the boot up state. - In the pm resume path asic init will have set the power state back to the default so reset the tracking state values.

This is needed to enable accel in the ddx. However, due to a bug in older versions of the ddx, it relies on accel being disabled in order to load properly on evergreen chips. To maintain compatility, we add a new get accel param and call that from the ddx. The old one always returns false for evergreen cards.

PM attemps to unmap objects that aren't actually mapped into userspace ever, so just don't bother unmapping them at this point, since all you are doing is nothing. We should be making sure all access to these objects are locked in kernel space instead. In theory the VRAM gart table is already done, and both the shaders and stolen vga memory blocks are never accessed at runtime. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16127Reported-by:

Commit 96d60303 (ahci: Turn off DMA engines when there's no device) implemented stopping DMA engines on empty ports but it used single sampling of status registers to determine device presence which led to disabling of DMA engines on occupied ports. Do it after all EH actions are complete using device presence state determined by EH. This avoids spurious disabling of DMA engines and simplifies the code. Signed-off-by:
