2014-05-15drm/i915: Increase WM memory latency values on SNBVille Syrjälä1-0/+40
On SNB the BIOS provided WM memory latency values seem insufficient to handle high resolution displays. In this particular case the display mode was a 2560x1440@60Hz, which makes the pixel clock 241.5 MHz. It was empirically found that a memory latency value if 1.2 usec is enough to avoid underruns, whereas the BIOS provided value of 0.7 usec was clearly too low. Incidentally 1.2 usec is what the typical BIOS provided values are on IVB systems. Increase the WM memory latency values to at least 1.2 usec on SNB. Hopefully this won't have a significant effect on power consumption. v2: Increase the latency values regardless of the pixel clock Cc: Robert N <crshman@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=70254 Tested-by: Robert Navarro <crshman@gmail.com> Tested-by: Vitaly Minko <vitaly.minko@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2014-05-15drm/i915: restore backlight precision when converting from ACPIAaron Lu1-4/+4
When we set backlight on behalf of ACPI opregion, we will convert the backlight value in the 0-255 range defined in opregion to the actual hardware level. Commit 22505b82a2 (drm/i915: avoid brightness overflow when doing scale) is meant to fix the overflow problem when doing the conversion, but it also caused a problem that the converted hardware level doesn't quite represent the intended value: say user wants maximum backlight level(255 in opregion's range), then we will calculate the actual hardware level to be: level = freq / max * level, where freq is the hardware's max backlight level(937 on an user's box), and max and level are all 255. The converted value should be 937 but the above calculation will yield 765. To fix this issue, just use 64 bits to do the calculation to keep the precision and avoid overflow at the same time.

2014-05-15drm/i915: Use the first mode if there is no preferred mode in the EDIDChris Wilson1-0/+9
This matches the algorithm used by earlier kernels when selecting the mode for the fbcon. And only if there is no modes at all, do we fall back to using the BIOS configuration. Seamless transition is still preserved (from the BIOS configuration to ours) so long as the BIOS has also chosen what we hope is the native configuration.

2014-05-15drm/i915/dp: force eDP lane count to max available lanes on BDWJani Nikula1-1/+6
There are certain BDW high res eDP machines that regressed due to commit 38aecea0ccbb909d635619cba22f1891e589b434 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Mar 3 11:18:10 2014 +0100 drm/i915: reverse dp link param selection, prefer fast over wide again The commit lead to 2 lanes at 5.4 Gbps being used instead of 4 lanes at 2.7 Gbps on the affected machines. Link training succeeded for both, but the screen remained blank with the former config. Further investigation showed that 4 lanes at 5.4 Gbps worked also. The root cause for the blank screen using 2 lanes remains unknown, but apparently the driver for a certain other operating system by default uses the max available lanes. Follow suit on Broadwell eDP, for at least until we figure out what is going on.

2014-05-06drm/radeon: Fix num_banks calculation for SIMichel Dänzer1-15/+31
The way the tile mode array index was calculated only makes sense for the CIK specific macrotile mode array. For SI, we need to use one of the tile mode array indices reserved for displayable surfaces. This happened to result in correct display most if not all of the time because most of the SI tiling modes use the same number of banks.

2014-05-06md: avoid possible spinning md thread at shutdown.NeilBrown1-1/+2
If an md array with externally managed metadata (e.g. DDF or IMSM) is in use, then we should not set safemode==2 at shutdown because: 1/ this is ineffective: user-space need to be involved in any 'safemode' handling, 2/ The safemode management code doesn't cope with safemode==2 on external metadata and md_check_recover enters an infinite loop. Even at shutdown, an infinite-looping process can be problematic, so this could cause shutdown to hang. Cc: stable@vger.kernel.org (any kernel) Signed-off-by: NeilBrown <neilb@suse.de>
2014-05-06md/raid10: call wait_barrier() for each request submitted.NeilBrown1-6/+7
wait_barrier() includes a counter, so we must call it precisely once (unless balanced by allow_barrier()) for each request submitted. Since commit 20d0189b1012a37d2533a87fb451f7852f2418d1 block: Introduce new bio_split() in 3.14-rc1, we don't call it for the extra requests generated when we need to split a bio. When this happens the counter goes negative, any resync/recovery will never start, and "mdadm --stop" will hang.
