drm: Add SCDC helpers

2017-03-21T08:15:39+00:00

SCDC is a mechanism defined in the HDMI 2.0 specification that allows the source and sink devices to communicate. This commit introduces helpers to access the SCDC and provides the symbolic names for the various registers defined in the specification. V2: Rebase. V3: Added R-B from Jose. V4: Rebase V5: Addressed review comments from Ville - Handle the I2c return values in a better way (dp_dual_mode) - Make the macros for SCDC Major/Minor more readable, by adding a 'GET' in the macro names V6: Rebase V7: Rebase V8: Rebase V9: Rebase V10: Rebase Signed-off-by: Thierry Reding Signed-off-by: Shashank Sharma Reviewed-by: Jose Abreu Signed-off-by: Jani Nikula Link: http://patchwork.freedesktop.org/patch/msgid/1489404244-16608-2-git-send-email-shashank.sharma@intel.com

Merge branch 'drm/next/platform' of git://linuxtv.org/pinchartl/media into drm-misc-next

2017-03-11T10:46:03+00:00

Merge Laurent's drm_platform removal code. Only conflict is with the drm_pci.h extraction, which allows me to fix up the misplayed drm_platform_init fumble that 0day and Stephen Rothwell reported. Signed-off-by: Daniel Vetter

drm: rename drm_fops.c to drm_file.c

2017-03-09T15:18:02+00:00

It's not just file ops, but drm_file stuff in general. This is prep work to extracting a drm_file.h header in the next patch. Reviewed-by: Gustavo Padovan Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170308141257.12119-8-daniel.vetter@ffwll.ch

drm: Add DRM support for tiny LCD displays

tinydrm provides helpers for very simple displays that can use CMA backed framebuffers and need flushing on changes. Signed-off-by: Noralf Trønnes Acked-by: Daniel Vetter Acked-by: Thierry Reding

drm: Remove unused drm_platform midlayer

Now that the last driver has been converted, the drm_platform midlayer is unused. Remove it. Signed-off-by: Laurent Pinchart Reviewed-by: Daniel Vetter

drm: compile drm_vm.c only when needed

2017-01-06T10:03:07+00:00

drm_vm.c functions are only need for DRM_LEGACY and DRM_NOUVEAU. Use a new DRM_VM to define when drm_vm.c in needed. stub drm_legacy_vma_flush() to avoid compilation issues version 4: - a "config DRM_VM" in Kconfig Signed-off-by: Benjamin Gaignard [danvet: Fix conflict.] Signed-off-by: Daniel Vetter

drm: Add some kselftests for the DRM range manager (struct drm_mm)

2016-12-27T11:34:39+00:00

First we introduce a smattering of infrastructure for writing selftests. The idea is that we have a test module that exercises a particular portion of the exported API, and that module provides a set of tests that can either be run as an ensemble via kselftest or individually via an igt harness (in this case igt/drm_mm). To accommodate selecting individual tests, we export a boolean parameter to control selection of each test - that is hidden inside a bunch of reusable boilerplate macros to keep writing the tests simple. v2: Choose a random random_seed unless one is specified by the user. v3: More parameters to control max_iterations and max_prime of the tests.

drm: Add a simple generator of random permutations

2016-12-27T11:34:00+00:00

When testing, we want a random but yet reproducible order in which to process elements. Here we create an array which is a random (using the Tausworthe PRNG) permutation of the order in which to execute.
