drm/tegra: Don't use vblank_disable_immediate on incapable driver.

2015-05-08T10:56:34Z

Tegra would not only need a hardware vblank counter that increments at leading edge of vblank, but also support for instantaneous high precision vblank timestamp queries, ie. a proper implementation of dev->driver->get_vblank_timestamp(). Without these, there can be off-by-one errors during vblank disable/enable if the scanout is inside vblank at en/disable time, and additionally clients will never see any useable vblank timestamps when querying via drmWaitVblank ioctl. This would negatively affect swap scheduling under X11 and Wayland. Signed-off-by: Mario Kleiner Acked-by: Thierry Reding Signed-off-by: Dave Airlie

Merge tag 'drm/tegra/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

2015-04-08T01:13:06Z

drm/tegra: Changes for v4.1-rc1 Perhaps the most noteworthy change in this set is the implementation of a hardware VBLANK counter using host1x syncpoints. The SOR registers can now be dumped via debugfs, which can be useful while debugging. The IOVA address space maintained by the driver can also be dumped via debugfs. Other than than, these changes are mostly cleanup work, such as making register names more consistent or removing unused code (that was left over after the atomic mode-setting conversion). There's also a fix for eDP that makes the driver cope with firmware that already initialized the display (such as the firmware on the Tegra-based Chromebooks). * tag 'drm/tegra/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: sor: Reset during initialization drm/tegra: gem: Return 64-bit offset for mmap(2) drm/tegra: hdmi: Name register fields consistently drm/tegra: hdmi: Resets are synchronous drm/tegra: dc: Document tegra_dc_state_setup_clock() drm/tegra: dc: Remove unused callbacks drm/tegra: dc: Remove unused function drm/tegra: dc: Use base atomic state helpers drm/atomic: Add helpers for state-subclassing drivers drm/tegra: dc: Implement hardware VBLANK counter gpu: host1x: Export host1x_syncpt_read() drm/tegra: sor: Dump registers via debugfs drm/tegra: sor: Registers are 32-bit drm/tegra: Provide debugfs file for the IOVA space drm/tegra: dc: Check for valid parent clock

drm/tegra: dc: Implement hardware VBLANK counter

2015-04-02T16:46:21Z

The display controller on Tegra can use syncpoints to count VBLANK events. syncpoints are 32-bit unsigned integers, so well suited as VBLANK counters. Signed-off-by: Thierry Reding

drm/tegra: Provide debugfs file for the IOVA space

2015-04-02T16:46:14Z

The Tegra DRM driver uses a single IO virtual address space for buffer mappings. Provide a table of the address space usage in debugfs. Signed-off-by: Thierry Reding

drm/atomic-helper: Rename commmit_post/pre_planes

2015-02-24T00:57:46Z

These names only make sense because of backwards compatability with the order used by the crtc helper library. There's not really any real requirement in the ordering here. So rename them to something more descriptive and update the kerneldoc a bit. Motivated in a discussion with Laurent about how to restore plane state for dpms for drivers with runtime pm. v2: Squash in fixup from Stephen Rothwell to fix a conflict with tegra.

drm/tegra: Use correct relocation target offsets

drm/tegra: Add minimal power management

drm/tegra: Atomic conversion, phase 3, step 3

2015-01-27T09:14:55Z

Provide a custom ->atomic_commit() implementation which supports async commits. The generic atomic page-flip helper can use this to implement page-flipping. Signed-off-by: Thierry Reding

drm/tegra: Atomic conversion, phase 3, step 1

2015-01-27T09:14:51Z

Switch out the regular plane helpers for the atomic plane helpers. Also use the default atomic helpers to implement the ->atomic_check() and ->atomic_commit() callbacks. The driver now exclusively uses the atomic interfaces. Signed-off-by: Thierry Reding

drm/tegra: Atomic conversion, phase 2

2015-01-27T09:14:51Z

Hook up the default ->reset() and ->atomic_duplicate_state() helpers. This ensures that state objects are properly created and framebuffer reference counts correctly maintained. Signed-off-by: Thierry Reding
