2013-08-08drm: Don't pass negative delta to ktime_sub_ns()Michel Dänzer1-1/+4
It takes an unsigned value. This happens not to blow up on 64-bit architectures, but it does on 32-bit, causing drm_calc_vbltimestamp_from_scanoutpos() to calculate totally bogus timestamps for vblank events. Which in turn causes e.g. gnome-shell to hang after a DPMS off cycle with current xf86-video-ati Git.

2013-08-07drm/i915: do not disable backlight on vgaswitcheroo switch offJani Nikula1-0/+11
On muxed systems, the other vgaswitcheroo client may depend on i915 to handle the backlight. We began switching off the backlight since commit a261b246ebd552fd5d5a8ed84cc931bb821c427f Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Jul 26 19:21:47 2012 +0200 drm/i915: disable all crtcs at suspend time breaking backlight on discreet graphics in (some) muxed systems. Keep the backlight on when the state is changed through vgaswitcheroo. Note: The alternative would be to add a quirk table to achieve the same based on system identifiers, but AFAICS it would asymptotically approach effectively the same as this patch as more IDs are added, but with the maintenance burden of the quirk table.

2013-08-07drm/i915: Don't call encoder's get_config unless encoder is activeVille Syrjälä1-1/+3
The SDVO code tries to compare the encoder's and crtc's idea of the pixel_multiplier. Normally they have to match, but when transitioning to DPMS off, we turn off the pipe before reading out the pipe_config, so the pixel_multiplier in the pipe_config will be 0, whereas the encoder will still have its pixel_multiplier set to whatever value we were using when the display was active. This leads to a warning from intel_modeset_check_state().

2013-08-07drm/i915: avoid brightness overflow when doing scaleAaron Lu1-2/+5
Some card's max brightness level is pretty large, e.g. on Acer Aspire 4732Z, the max level is 989910. If user space set a large enough level then the current scale done in intel_panel_set_backlight will cause an integer overflow and the scaled level will be mistakenly small, leaving user with an almost black screen.

2013-08-07drm/i915: update last_vblank when disabling the power wellPaulo Zanoni1-0/+18
The DRM layer keeps track of our vblanks and it assumes our vblank counters only go back to zero when they overflow. The problem is that when we disable the power well our counters also go to zero, but it doesn't mean they did overflow. So on this patch we grab the lock and update last_vblank so the DRM layer won't think our counters overflowed. This patch fixes the following intel-gpu-tools test: ./kms_flip --run-subtest blocking-absolute-wf_vblank Regression introduced by the following commit: commit bf51d5e2cda5d36d98e4b46ac7fca9461e512c41 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Wed Jul 3 17:12:13 2013 -0300 drm/i915: switch disable_power_well default value to 1 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=66808 Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> [danvet: Added a comment that this might be better done in drm_vblank_post_modeset in general.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-08-07drm/i915: fix gen4 digital port hotplug definitionsDaniel Vetter1-3/+9
Apparently Bspec is wrong in this case here even for gm45. Note that Bspec is horribly misguided on i965g/gm, so we don't have any other data points besides that it seems to make machines work better. With this changes all the bits in PORT_HOTPLUG_STAT for the digital ports are ordered the same way. This seems to agree with what register dumps from the hpd storm handling code shows, where the LIVE bit and the short/long pulse STATUS bits light up at the same time with this enumeration (but no with the one from Bspec). Also tested on my gm45 which has two DP+ ports, and everything seems to still work as expected.

Set bo.mdev->dev_mapping in mgag200_bo_create() to make sure that ttm_bo_unmap_virtual() called from ttm_bo_handle_move_mem() will take care of this. v2: Don't call ttm_bo_unmap_virtual() in mgag200_bo_pin(), fix comment.

2013-08-07drm/cirrus: Invalidate page tables when pinning a BOMichal Srb1-0/+1
This is a cirrus version of Egbert Eich's patch for mgag200. Without bo.bdev->dev_mapping set, the ttm_bo_unmap_virtual_locked called from ttm_bo_handle_move_mem returns with no effect. If any application accessed the memory before it was moved, it will access wrong memory next time. This causes crashes when changing resolution down.

Commits 0a9e2b959 (drm/nvd0/disp: move HDA codec setup to core) and a4feaf4ea (drm/nva3/disp: move hda codec handling to core) moved code around but neglected to fill data up to 0x60 as before. This caused /proc/asound/cardN/eld#3.0 to show eld_valid as 0. With this patch, that file is again populated with the correct data.

2013-07-30drm/nv50/gpio: post-nv92 cards have 32 interrupt linesEmil Velikov1-5/+5
Since the original merge of nouveau to upstream kernel, we were assuming that nv90 (and later) cards have 32 lines. Based on mmio traces of the binary driver, as well as PBUS error messages during read/write of the e070/e074 registers, we can conclude that nv92 has only 16 lines whereas nv94 (and later) cards have 32.

2013-07-30drm/nvc0/fb: take lock in nvc0_ram_put()Roy Spliet3-12/+26
Kernel panic caused by list corruption in ltcg seems to indicate a concurrency issue. Take mutex of pfb like nv50_ram_put() to eliminate concurrency. V2: Separate critical section into separate function, avoid taking the lock twice on NVC0 Signed-off-by: Roy Spliet <r.spliet@student.tudelft.nl> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-07-30drm/nouveau/core: xtensa firmware size needs to be 0x40000 no matter whatIlia Mirkin1-1/+7
The current logic is wrong since we send fw->size >> 8 to the card. Rounding the size up by 0x100 and 0x1000 didn't seem to help, the card still hung, so go back to what the blob does -- 0x40000. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-07-30drm/mgag200: Fix LUT programming for 16bppEgbert Eich1-0/+23
Since there are only 32 (64) distinct color values for each color in 16bpp Matrox hardware expects those in a 'dense' manner, ie in the first 32 (64) entries of the respective color. Signed-off-by: Egbert Eich <eich@suse.de> Signed-off-by: Dave Airlie <airlied@redhat.com>
