2013-11-13drm/i915: fix gen2-gen3 backlight setJani Nikula
Citing Jani's response to Imre's question in the review discussion: > According to the gen2/3 bspec I have, the correct mask is > BACKLIGHT_DUTY_CYCLE_MASK_PNV only in case of IS_PINEVIEW(dev), for > everything else it's BACKLIGHT_DUTY_CYCLE_MASK. What you say is correct, but we've treated all gen2/3 similar to PNV since commit ca88479c1c3b7b1a9f94320745f5331e1de77f80 Author: Keith Packard <keithp@keithp.com> Date: Fri Nov 18 11:09:24 2011 -0800 drm/i915: Treat pre-gen4 backlight duty cycle value consistently i.e. we only use the high 15 bits for all gen2/3. For non-PNV this just means the lowest bit is always zero. For PNV the lowest bit has a different meaning in both the PWM freq and duty cycle fields.

Preallocated objects will already have been added to the vma_list when creating their ggtt vma entry, and coincidentally also marked as holding a ggtt mapping.

2013-11-13drm/i915: handle backlight through chip specific functionsJani Nikula
The backlight code has grown rather hairy, not least because the hardware registers and bits have repeatedly been shuffled around. And this isn't expected to get any easier with new hardware. Make things easier for our (read: my) poor brains, and split the code up into chip specific functions. There should be no functional changes.

git://people.freedesktop.org/~danvet/drm-intel into drm-next So here's the Broadwell pull request. From a kernel driver pov there's two areas with big changes in Broadwell: - Completely new enumerated interrupt bits. On the plus side it now looks fairly unform and sane. - Completely new pagetable layout. To ensure minimal impact on existing platforms we've refactored both the irq and low-level gtt handling code a lot in anticipation of the bdw push. So now bdw enabling in these areas just plugs in a bunch of vfuncs. Otherwise it's all fairly harmless adjusting of switch cases and if-ladders to shovel bdw into the right blocks. So minimized impact on existing platforms. I've also merged the bdw-stage1 branch into our -nightly integration branch for the past week to make sure we don't break anything. Note that there's still quite a flurry or patches floating around, but I've figured I'll push this out. I plan to keep the bdw fixes separate from my usual -fixes stream so that you can reject them easily in case it still looks like too much churn. Also, bdw is for now hidden behind the preliminary hw enabling module option. So there's no real pressure to get follow-up patches all into 3.13. * tag 'bdw-stage1-2013-11-08-v2' of git://people.freedesktop.org/~danvet/drm-intel: (75 commits) drm/i915: Mask the vblank interrupt on bdw by default drm/i915: Wire up cpu fifo underrun reporting support for bdw drm/i915: Optimize gen8_enable|disable_vblank functions drm/i915: Wire up pipe CRC support for bdw drm/i915: Wire up PCH interrupts for bdw drm/i915: Wire up port A aux channel drm/i915: Fix up the bdw pipe interrupt enable lists drm/i915: Optimize pipe irq handling on bdw drm/i915/bdw: Take render error interrupt out of the mask drm/i915/bdw: Add BDW PCH check first drm/i915: Use hsw_crt_get_config on BDW drm/i915/bdw: Change dp aux timeout to 600us on DDIA drm/i915/bdw: Enable trickle feed on Broadwell drm/i915/bdw: WaSingleSubspanDispatchOnAALinesAndPoints drm/i915/bdw: conservative SBE VUE cache mode drm/i915/bdw: Limit SDE poly depth FIFO to 2 drm/i915/bdw: Sampler power bypass disable ddrm/i915/bdw: Disable centroid pixel perf optimization drm/i915/bdw: BWGTLB clock gate disable drm/i915/bdw: Implement edp PSR workarounds ...

This can later (when the mode on that CRTC is setup again from user space) cause ***_do_set_base functions to "think" that there is no old buffer and skip the unpinning code. Consequently, the buffer that has been NULL-ified in drm_helper_disable_unused_functions will never be unpinned causing a leak in VRAM.

2013-11-08drm/radeon/audio: fix missing multichannel PCM SAD in some casesAnssi Hannula
The current code writing SADs to the audio registers seems to assume that there is at most a single SAD per audio format. However, that is not the case. Especially for PCM it is somewhat common for sinks to have two SADs, one for 8-channel and one for 2-channel audio, which may have different supported sample rates (i.e. the sink supports stereo audio at higher sample rates than multichannel audio). Because of this, only the 2-channel SAD may be used if it appears before the 8-channel SAD. Unless other SADs require otherwise, this may cause the ALSA HDA driver to allow stereo playback only. Fix the code to pick the PCM SAD with the highest number of channels, while merging the rate masks of PCM SADs with lower amount of channels into the additional stereo rate mask byte. Technically there are even more cases to handle (multiple non-PCM SADs of the same type, more than two PCM SADs with varying channel counts, etc), but those have not actually been encountered in the field and handling them would be non-trivial. Example affected EDID from Onkyo TX-SR674 specifying 192kHz stereo support and 96kHz 8-channel support (and other 8-channel compressed formats): 00ffffffffffff003dcb010000000001 ffff0103800000780a0dc9a057479827 12484c00000001010101010101010101 010101010101011d8018711c1620582c 2500c48e2100009e011d007251d01e20 6e285500c48e2100001e000000fc0054 582d53523637342020202020000000fd 00313d0f2e08000a202020202020019b 02032f724f8504030f0e07069413121e 1d1615012f097f070f1f071707503707 503f07c0834f000066030c00ffff808c 0ad08a20e02d10103e9600c48e210000 18011d80d0721c1620102c2580c48e21 00009e011d00bc52d01e20b8285540c4 8e2100001e8c0ad090204031200c4055 00c48e210000180000000000000000a8 Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Tested-by: Andre Heider <a.heider@gmail.com> Cc: Rafał Miłecki <zajec5@gmail.com> Acked-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
