2016-09-27drm/amdgpu: disable CRTCs before teardownGrazvydas Ignotas1-1/+1
Some code called by drm_crtc_force_disable_all() wants to wait for all fences, so only do fence teardown after CRTCs are disabled.

2016-09-19drm: Only use compat ioctl for addfb2 on X86/IA64Kristian H. Kristensen1-0/+4
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by: Rob Clark <[email protected]> Signed-off-by: Kristian H.

When CONFIG_PM is not set, we get a warning about an unused function: drivers/gpu/drm/exynos/exynos_drm_gsc.c:1219:12: error: 'gsc_clk_ctrl' defined but not used [-Werror=unused-function] static int gsc_clk_ctrl(struct gsc_context *ctx, bool enable) ^~~~~~~~~~~~ This removes the two #ifdef checks in this file and instead marks the functions as __maybe_unused, which is a more reliable way of doing the same, allowing better build coverage and avoiding the warning above.

2016-09-14drm/i915: Ignore OpRegion panel type except on select machinesVille Syrjälä1-0/+27
Turns out commit a05628195a0d ("drm/i915: Get panel_type from OpRegion panel details") has regressed quite a few machines. So it looks like we can't use the panel type from OpRegion on all systems, and yet we absolutely must use it on some specific systems. Despite trying, I was unable to find any automagic way to determine if the OpRegion panel type is respectable or not. The only glimmer of hope I had was bit 8 in the SCIC response, but that turned out to not work either (it was always 0 on both types of systems). So, to fix the regressions without breaking the machine we know to need the OpRegion panel type, let's just add a quirk for this. Only specific machines known to require the OpRegion panel type will therefore use it. Everyone else will fall bck to the VBT panel type. The only known machine so far is a "Conrac GmbH IX45GM2". The PCI subsystem ID on this machine is just a generic 8086:2a42, so of no use. Instead we'll go with a DMI match. I suspect we can now also revert commit aeddda06c1a7 ("drm/i915: Ignore panel type from OpRegion on SKL") but let's leave that to a separate patch. v2: Do the DMI match in the opregion code directly, as dev_priv->quirks gets populated too late Cc: Rob Kramer <[email protected]> Cc: Martin van Es <[email protected]> Cc: Andrea Arcangeli <[email protected]> Cc: Dave Airlie <[email protected]> Cc: Marco Krüger <[email protected]> Cc: Sean Greenslade <[email protected]> Cc: Trudy Tective <[email protected]> Cc: Robin Müller <[email protected]> Cc: Alexander Kobel <[email protected]> Cc: Alexey Shumitsky <[email protected]> Cc: Emil Andersen Lauridsen <[email protected]> Cc: [email protected] Cc: James Hogan <[email protected]> Cc: James Bottomley <[email protected]> Cc: [email protected] References: https://lists.freedesktop.org/archives/intel-gfx/2016-August/105545.html References: https://lists.freedesktop.org/archives/dri-devel/2016-August/116888.html References: https://lists.freedesktop.org/archives/intel-gfx/2016-June/098826.html Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94825 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97060 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97443 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97363 Fixes: a05628195a0d ("drm/i915: Get panel_type from OpRegion panel details") Tested-by: Marco Krüger <[email protected]> Tested-by: Alexey Shumitsky <[email protected]> Tested-by: Sean Greenslade <[email protected]> Tested-by: Emil Andersen Lauridsen <[email protected]> Tested-by: Robin Müller <[email protected]> Tested-by: [email protected] Tested-by: Rob Kramer <[email protected]> Signed-off-by: Ville Syrjälä <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] References: http://patchwork.freedesktop.org/patch/msgid/[email protected] Acked-by: Jani Nikula <[email protected]> (cherry picked from commit c8ebfad7a063fe665417fa0eeb0da7cfe987d8ed) Signed-off-by: Jani Nikula <[email protected]>

This reverts commit 1c80c25fb622973dd135878e98d172be20859049 Author: Daniel Vetter <[email protected]> Date: Wed May 18 18:47:12 2016 +0200 drm/i915/psr: Make idle_frames sensible again There are panels that needs 4 idle frames before entering PSR, but VBT is unproperly set. Also lately it was identified that idle frame count calculated at HW can be off by 1, what makes the minimum of 2, at least. Without the current vbt+1 we are with the risk of having HW calculating 0 idle frames and entering PSR when it shouldn't. Regardless the lack of link training.

2016-08-31drm/nouveau/acpi: use DSM if bridge does not support D3coldPeter Wu1-0/+11
Even if PR3 support is available on the bridge, it will not be used if the PCI layer considers it unavailable (i.e. on all laptops from 2013 and 2014). Ensure that this condition is checked to allow a fallback to the Optimus DSM for device poweroff. Initially I wanted to call pci_d3cold_enable before checking bridge_d3 (in case the user changed d3cold_allowed), but that is such an unlikely case and likely fragile anyway.

property updates. Due to assigning the 'replaced' value instead of or'ing it, if drm_atomic_crtc_set_property() gets called multiple times, the last call will define the color_mgmt_changed flag, so a non-updating call to a property can reset the flag and prevent actual hw state updates required by preceding property updates.
