* drm/msm: Enable clocks during enable/disable_vblank() callbacksHai Li2015-08-161-2/+76
| | | | | | | | | | | | | AHB clock should be enabled before accessing registers during enable/disable_vblank(). Since these 2 callbacks are called in atomic context while clk_prepare may cause thread sleep, a work is scheduled to control vblanks. v2: fixup spinlock initialization Signed-off-by: Hai Li <hali@codeaurora.org> [add comment about cancel_work_sync() before drm_irq_uninstall()] Signed-off-by: Rob Clark <robdclark@gmail.com>
* drm/msm: Set different display size limitation on each targetHai Li2015-08-161-4/+0
| | | | | | | | | | | | | The maximum output width of one pipeline depends on the LayerMixer's capability. It may be different on each target. Also, MDP5 doesn't have vertical limitation in one frame, as long as the pixel clock can be supported. This change obtains the maximum LM resolution from configuration table and treat it as the whole pipe's limitation for MDP5. The size limit on MDP4 is not changed.

* drm/msm: fix timeout calculationRob Clark2015-06-111-10/+16
| | | | | | | | | | | | | | | | | | The 'timeout' value comes from userspace (CLOCK_MONOTONIC), but converting this directly to jiffies doesn't take into account the initial jiffies count at boot, which may differ from the base time of CLOCK_MONOTONIC. TODO: add ktime_delta_jiffies() when rebasing on 4.1 and use that instead of ktime_sub/ktime_to_timespec/timespec_to_jiffies combo (as suggested by Arnd) v2: switch over from 'struct timespec' to ktime_t throughout, since 'struct timespec' will be deprecated (as suggested by Arnd) v3: minor cosmetic tweaks Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Rob Clark <robdclark@gmail.com>

Most important is the propertification from Rob and the nth iteration of the actual atomic ioctl originally from Ville. Big differences compared to earlier revisions: - Core properties are now fully handled by the core, drivers can only handle driver-specific properties. - Atomic props&ioctl are opt-in per file_priv, userspace needs to explicitly ask for it (like universal plane support). - For now all hidden behind the atomic module option until this has settled a bit. - Atomic modesets are currently not possible since the exact abi for how to handle the mode property is still under discussion. Besides this some cleanup patches from me and the addition of per-object state to global state backpointers to simplify drivers. * tag 'topic/atomic-core-2015-01-05' of git://anongit.freedesktop.org/drm-intel: drm: Ensure universal_planes is set for atomic drm/atomic: Hide drm.ko internal interfaces drm: Atomic modeset ioctl drm/atomic: atomic connector properties drm/atomic: atomic plane properties drm: small property creation cleanup drm/atomic: atomic_check functions drm: add atomic properties drm: refactor getproperties/getconnector drm: tweak getconnector locking drm: add atomic_get_property drm: add atomic_set_property wrappers drm: get rid of direct property value access drm: store property instead of id in obj attachment drm: allow property validation for refcnted props drm/atomic: Introduce state->obj backpointers drm/atomic-helper: Again check modeset *before* plane states drm/atomic-helper: Export both plane and modeset check helpers

The failure mode in the first case is usually a totally angry hw because the pixel format switching doesn't happen. The failure mode in the later case is usually nothing, since in most cases the old adjusted mode from the previous modeset wont be too far off to be a problem. So just underruns and perhaps even just suboptimal (from a power consumption) watermarks. Furthermore in the transitional helpers we only call ->atomic_check after the new modeset state has been fully set up (and hence computed). Given that asymmetry in expected failure modes I think it's safer to go back to the older order. So do that and give msm a special check function to compensate. Also update kerneldoc to explain this a bit. v2: Actually add the missing hunk Rob spotted. v3: Move msm_atomic_check into msm_atomic.c, requested by Rob.

* drm/msm: add support for non-IOMMU systemsRob Clark2014-01-091-35/+52
| | | | | | | | | | | | | | | | | | | | | | Add a VRAM carveout that is used for systems which do not have an IOMMU. The VRAM carveout uses CMA. The arch code must setup a CMA pool for the device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not cool). The user can configure the VRAM pool size using msm.vram module param. Technically, the abstraction of IOMMU behind msm_mmu is not strictly needed, but it simplifies the GEM code a bit, and will be useful later when I add support for a2xx devices with GPUMMU, so I decided to keep this part. It appears to be possible to configure the GPU to restrict access to addresses within the VRAM pool, but this is not done yet. So for now the GPU will refuse to load if there is no sort of mmu. Once address based limits are supported and tested to confirm that we aren't giving the GPU access to arbitrary memory, this restriction can be lifted Signed-off-by: Rob Clark <robdclark@gmail.com>

* drm/msm: rework inactive-workRob Clark2013-11-011-4/+26
| | | | | | | | | | | | Re-arrange things a bit so that we can get work requested after a bo fence passes, like pageflip, done before retiring bo's. Without any sort of bo cache in userspace, some games can trigger hundred's of transient bo's, which can cause retire to take a long time (5-10ms). Obviously we want a bo cache.. but this cleanup will make things a bit easier for atomic as well and makes things a bit cleaner.
