  • 5620ae29f   drm/i915: make sure we shut off the panel in eDP configs ... Browse Code »

    Fix error from the last pull request. Making sure we shut the panel off
    is more correct and saves power.

    At module unload time we'll tear down the fbdev state. We do so under
    the struct mutex, so we shouldn't try to use the unlocked variant of

    This fixes a potential modesetting error during boot with plymouth on
    Broadwater and Crestline introduced with 9df47c. The framebuffer was
    hard-coding an alignment of 64K, but the modesetting code required the
    documented alignment of 128K. The result was that we would attempt to
    unbind the pinned fbcon buffer, triggering an ERROR and ultimately
    failing the mode change.

  • 9934c1329   drm/i915: make sure eDP panel is turned on ... Browse Code »

    When enabling the eDP port, we need to make sure the panel is turned on
    after training the link. If we don't, it likely won't come back after
    suspend or may not come up at all.

    For unknown reasons, unlocking the panel regs before initiating a power
    on sequence is necessary. There are known bugs in the PCH panel
    sequencing logic, apparently this is one possible workaround.

  • 6ba770dc5   drm/i915: Make G4X-style PLL search more permissive ... Browse Code »

    Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC
    reference clock.

    More generally, the 0.488% tolerance used before is just too tight to
    reliably find a PLL setting. I extracted the search algorithm and
    modified it to find the dot clocks with maximum error over the valid
    range for the given output type:

    http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c

    This gave:

    Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571)
    Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524)
    Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488)
    Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529)
    Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488)
    Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448)
    Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478)
    Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449)

  • a392a1036   drm/i915: Clear any existing dither mode prior to enabling spatial dithering ... Browse Code »

    We cannot the initial configuration set by the BIOS not to have a dither
    mode enabled which conflicts with our enabling the Spatial Temporal 1
    dither mode for PCH. In particular, the BIOS may either enable temporal
    dithering or the Spatial Temporal 2 with the result that we enable pure
    temporal dithering. Temporal dithering looks bad and is perceived as a
    flicker.

    On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
    which will break some setups.

    This patch also removes the different ordering of shadow methods for
    pre-nv50 chipsets. The reason for the different ordering was paranoia,
    but it should hopefully be OK to try shadowing PRAMIN first.

  • 42f14c4b4   drm/radeon/kms: fix shared ddc harder ... Browse Code »

    This fixes a regression caused by b2ea4aa67bfd084834edd070e0a4a47857d6db59
    due to the way shared ddc with multiple digital connectors was handled.

    You generally have two cases where DDC lines are shared:
    - HDMI + VGA
    - HDMI + DVI-D

    HDMI + VGA is easy to deal with because you can check the EDID for the
    to see if the attached monitor is digital. A shared DDC line with two
    digital connectors is more complex. You can't use the hdmi bits in the
    EDID since they may not be there with DVIHDMI adapters. In this case
    all we can do is check the HPD pins to see which is connected as we have
    no way of knowing using the EDID.

  • 7f8275d0d   mm: add context argument to shrinker callback ... Browse Code »

    The current shrinker implementation requires the registered callback
    to have global state to work from. This makes it difficult to shrink
    caches that are not global (e.g. per-filesystem caches). Pass the shrinker
    structure to the callback so that users can embed the shrinker structure
    in the context the shrinker needs to operate on and get back to it in the
    callback via container_of().

  • cd9f040df   drm/i915: add 'reclaimable' to i915 self-reclaimable page allocations ... Browse Code »

    The hibernate issues that got fixed in commit 985b823b9192 ("drm/i915:
    fix hibernation since i915 self-reclaim fixes") turn out to have been
    incomplete. Vefa Bicakci tested lots of hibernate cycles, and without
    the __GFP_RECLAIMABLE flag the system eventually fails to resume.

    With the flag added, Vefa can apparently hibernate forever (or until he
    gets bored running his automated scripts, whichever comes first).

    The reclaimable flag was there originally, and was one of the flags that
    were dropped (unintentionally) by commit 4bdadb978569 ("drm/i915:
    Selectively enable self-reclaim") that introduced all these problems,
    but I didn't want to just blindly add back all the flags in commit
    985b823b9192, and it looked like __GFP_RECLAIM wasn't necessary. It
    clearly was.

    I still suspect that there is some subtle reason we're missing that
    causes the problems, but __GFP_RECLAIMABLE is certainly not wrong to use
    in this context, and is what the code historically used. And we have no
    idea what the causes the corruption without it.

    The asics in question have the following requirements with regard to
    their gart setups:

    1. The GART aperture size has to be in the form of 2^X bytes, where X is from 25 to 31
    2. The GART aperture MC base has to be aligned to a boundary equal to the size of the
    aperture.
    3. The GART page table has to be aligned to the boundary equal to the size of the table.
    4. The GART page table size is: table_entry_size * (aperture_size / page_size)
    5. The GART page table has to be allocated in non-paged, non-cached, contiguous system
    memory.

    This patch takes care 2. The rest should already be handled properly.
