2015-03-04drm/msm: kexec fixesRob Clark2-0/+10
In kexec environment, we are more likely to encounter irq's already enabled from previous environment. At which point we find that writes to disable/clear pending irq's are slightly less than useless without first enabling clocks.

2015-03-04drm/msm/mdp5: Avoid flushing registers when CRTC is disabledStephane Viau1-7/+19
When a CRTC is disabled, no CTL is allocated to it (CRTC->ctl == NULL); in that case we should not try to FLUSH registers and do nothing instead. This can happen when we try to move a cursor but the CRTC's CTL (CONTROL) has not been allocated yet (inactive CRTC). It can also happens when we .atomic_check()/.atomic_flush() on a disabled CRTC. A CTL needs to be kept as long as the CRTC is alive. Releasing it after the last VBlank is safer than in .atomic_flush().

2015-03-05drm/ttm: device address space != CPU address spaceAlex Deucher2-2/+2
We need to store device offsets in 64 bit as the device address space may be larger than the CPU's. Fixes GPU init failures on radeons with 4GB or more of vram on 32 bit kernels. We put vram at the start of the GPU's address space so the gart aperture starts at 4 GB causing all GPU addresses in the gart aperture to get truncated. bug: https://bugs.freedesktop.org/show_bug.cgi?id=89072 [airlied: fix warning on nouveau build] Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: thellstrom@vmware.com Acked-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2015-03-05drm/mm: Support 4 GiB and larger rangesThierry Reding3-78/+84
The current implementation is limited by the number of addresses that fit into an unsigned long. This causes problems on 32-bit Tegra where unsigned long is 32-bit but drm_mm is used to manage an IOVA space of 4 GiB. Given the 32-bit limitation, the range is limited to 4 GiB - 1 (or 4 GiB - 4 KiB for page granularity). This commit changes the start and size of the range to be an unsigned 64-bit integer, thus allowing much larger ranges to be supported.

2015-03-04drm/i915: gen4: work around hang during hibernationImre Deak1-5/+25
Bjørn reported that his machine hang during hibernation and eventually bisected the problem to the following commit: commit da2bc1b9db3351addd293e5b82757efe1f77ed1d Author: Imre Deak <imre.deak@intel.com> Date: Thu Oct 23 19:23:26 2014 +0300 drm/i915: add poweroff_late handler The problem seems to be that after the kernel puts the device into D3 the BIOS still tries to access it, or otherwise assumes that it's in D0. This is clearly bogus, since ACPI mandates that devices are put into D3 by the OSPM if they are not wake-up sources. In the future we want to unify more of the driver's runtime and system suspend paths, for example by skipping all the system suspend/hibernation hooks if the device is runtime suspended already. Accordingly for all other platforms the goal is still to properly power down the device during hibernation. v2: - Another GEN4 Lenovo laptop had the same issue, while platforms from other vendors (including mobile and desktop, GEN4 and non-GEN4) seem to work fine. Based on this apply the workaround on all GEN4 Lenovo platforms. - add code comment about failing platforms (Ville) Reference: http://lists.freedesktop.org/archives/intel-gfx/2015-February/060633.html Reported-and-bisected-by: Bjørn Mork <bjorn@mork.no> Cc: stable@vger.kernel.org # v3.19 Signed-off-by: Imre Deak <imre.deak@intel.com> Acked-by: Daniel Vetter <daniel.vetter@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2015-03-04drm/i915: Check for driver readyness before handling an underrun interruptChris Wilson1-11/+7
When we takeover from the BIOS and install our interrupt handler, the BIOS may have left us a few surprises in the form of spontaneous interrupts. (This is especially likely on hardware like 965gm where display fifo underruns are continuous and the GMCH cannot filter that interrupt souce.) As we enable our IRQ early so that we can use it during hardware probing, our interrupt handler must be prepared to handle a few sources prior to being fully configured. As such, we need to add a simple is-ready check prior to dereferencing our KMS state for reporting underruns.

2015-03-03drm/i915: Fix modeset state confusion in the load detect codeDaniel Vetter1-0/+1
This is a tricky story of the new atomic state handling and the legacy code fighting over each another. The bug at hand is an underrun of the framebuffer reference with subsequent hilarity caused by the load detect code. Which is peculiar since the the exact same code works fine as the implementation of the legacy setcrtc ioctl. Let's look at the ingredients: - Currently our code is a crazy mix of legacy modeset interfaces to set the parameters and half-baked atomic state tracking underneath. While this transition is going we're using the transitional plane helpers to update the atomic side (drm_plane_helper_disable/update and friends), i.e. plane->state->fb. Since the state structure owns the fb those functions take care of that themselves. The legacy state (specifically crtc->primary->fb) is still managed by the old code (and mostly by the drm core), with the fb reference counting done by callers (core drm for the ioctl or the i915 load detect code). The relevant commit is commit ea2c67bb4affa84080c616920f3899f123786e56 Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Dec 23 10:41:52 2014 -0800 drm/i915: Move to atomic plane helpers (v9) - drm_plane_helper_disable has special code to handle multiple calls in a row - it checks plane->crtc == NULL and bails out. This is to match the proper atomic implementation which needs the crtc to get at the implied locking context atomic updates always need. See commit acf24a395c5a9290189b080383564437101d411c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Jul 29 15:33:05 2014 +0200 drm/plane-helper: transitional atomic plane helpers - The universal plane code split out the implicit primary plane from the CRTC into it's own full-blown drm_plane object. As part of that the setcrtc ioctl (which updated both the crtc mode and primary plane) learned to set crtc->primary->crtc on modeset to make sure the plane->crtc assignments statate up to date in commit e13161af80c185ecd8dc4641d0f5df58f9e3e0af Author: Matt Roper <matthew.d.roper@intel.com> Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) Unfortunately we've forgotten to update the load detect code. Which wasn't a problem since the load detect modeset is temporary and always undone before we drop the locks. - Finally there is a organically grown history (i.e. don't ask) around who sets the legacy plane->fb for the various driver entry points. Originally updating that was the drivers duty, but for almost all places we've moved that (plus updating the refcounts) into the core. Again the exception is the load detect code. Taking all together the following happens: - The load detect code doesn't set crtc->primary->crtc. This is only really an issue on crtcs never before used or when userspace explicitly disabled the primary plane. - The plane helper glue code short-circuits because of that and leaves a non-NULL fb behind in plane->state->fb and plane->fb. The state fb isn't a real problem (it's properly refcounted on its own), it's just the canary. - Load detect code drops the reference for that fb, but doesn't set plane->fb = NULL. This is ok since it's still living in that old world where drivers had to clear the pointer but the core/callers handled the refcounting. - On the next modeset the drm core notices plane->fb and takes care of refcounting it properly by doing another unref. This drops the refcount to zero, leaving state->plane now pointing at freed memory. - intel_plane_duplicate_state still assume it owns a reference to that very state->fb and bad things start to happen. Fix this all by applying the same duct-tape as for the legacy setcrtc ioctl code and set crtc->primary->crtc properly.

2015-02-25drm/radeon: only enable DP audio if the monitor supports itAlex Deucher1-6/+15
We were enabling DP secondary streams even if the monitor didn't support them. Fixes display problems on some DP monitors. Tested-by: Jim Boz <jim876@xs4all.nl> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2015-02-25drm/radeon: fix atom aux payload size check for writes (v2)Alex Deucher1-0/+7
The atom aux param interface only supports 4 bits for the total write transfer size (header + payload). This limits us to 12 bytes of payload rather than 16. Add a check for this. Reads are not affected. v2: switch to WARN_ON_ONCE Reviewed-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2015-02-25drm/i915: Fix frontbuffer false positve.Rodrigo Vivi1-3/+0
This return 0 without setting atomic bits on fb == crtc->cursor->fb where causing frontbuffer false positives. According to Daniel: The original regression seems to have been introduced in the original check/commit split: commit 757f9a3e5b8a812af0c213099a5b31cb423f4d3c Author: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Date: Wed Sep 24 14:20:24 2014 -0300 drm/i915: move check of intel_crtc_cursor_set_obj() out Which already cause other trouble, resulting in the check getting moved in commit e391ea882b1a04fb3f559287ac694652a3cd9da9 Author: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Date: Wed Sep 24 14:20:25 2014 -0300 drm/i915: Fix not checking cursor and object sizes The frontbuffer tracking itself only was broken when we shifted it into the check/commit logic with: commit 32b7eeec4d1e861230b09d437e95d76c86ff4a68 Author: Matt Roper <matthew.d.roper@intel.com> Date: Wed Dec 24 07:59:06 2014 -0800 drm/i915: Refactor work that can sleep out of commit (v7) v2: When putting more debug prints I notice the solution was simpler than I thought. AMS design is solid, just this return was wrong. Sorry for the noise. v3: Remove the entire chunck that would probably be removed by gcc anyway.
