2019-11-28drm/selftests: Add drm_rect selftestsVille Syrjälä
Add selftests for drm_rect. A few basic ones for clipped and unclipped cases, and a few special ones for specific bugs we had in the code. I'm too lazy to think of more corner cases to check at this time. Maybe later.

2019-11-20drm/r128: make ATI PCI GART part of its only user, r128Jani Nikula
The ATI Rage 128 driver has been the only user of ATI PCI GART code since Radeon dropped UMS support in commit 8333f607a631 ("drm/radeon: remove UMS support"). Clean up the drm top level directory, Kconfig and Makefile by making ati_pcigart.[ch] part of r128. Drop the CONFIG_DRM_ATI_PCIGART config option made redundant by the change. This reduces drm.ko module size slightly when legacy drivers are enabled, and moves the baggage to r128.ko instead.

2019-10-29drm/gem: Fix mmap fake offset handling for drm_gem_object_funcs.mmapRob Herring
Commit c40069cb7bd6 ("drm: add mmap() to drm_gem_object_funcs") introduced a GEM object mmap() hook which is expected to subtract the fake offset from vm_pgoff. However, for mmap() on dmabufs, there is not a fake offset. To fix this, let's always call mmap() object callback with an offset of 0, and leave it up to drm_gem_mmap_obj() to remove the fake offset. TTM still needs the fake offset, so we have to add it back until that's fixed.

2019-10-17drm: add mmap() to drm_gem_object_funcsGerd Hoffmann
drm_gem_object_funcs->vm_ops alone can't handle everything which needs to be done for mmap(), tweaking vm_flags for example. So add a new mmap() callback to drm_gem_object_funcs where this code can go to. Note that the vm_ops field is not used in case the mmap callback is present, it is expected that the callback sets vma->vm_ops instead. Also setting vm_flags and vm_page_prot is the job of the new callback. so drivers have more control over these flags. drm_gem_mmap_obj() will use the new callback for object specific mmap setup. With this in place the need for driver-speific fops->mmap callbacks goes away, drm_gem_mmap can be hooked instead. drm_gem_prime_mmap() will use the new callback too to just mmap gem objects directly instead of jumping though loops to make drm_gem_object_lookup() and fops->mmap work.

2019-10-15drm: Add LT-tunable PHY repeater mode operationsRodrigo Siqueira
LT-tunable PHY Repeaters can operate in two different modes: transparent (default) and non-transparent. The value 0x55 specifies the transparent mode, and 0xaa represents the non-transparent; this commit adds these two values as definitions.

2019-10-10drm/bridge: dw-hdmi: Add Dynamic Range and Mastering InfoFrame supportJonas Karlman
Add support for configuring Dynamic Range and Mastering InfoFrame from the hdr_output_metadata connector property. This patch adds a use_drm_infoframe flag to dw_hdmi_plat_data that platform drivers use to signal when Dynamic Range and Mastering infoframes is supported. This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version, and only GXL support DRM InfoFrame. These changes were based on work done by Zheng Yang <zhengyang@rock-chips.com> to support DRM InfoFrame on the Rockchip 4.4 BSP kernel at [1] and [2] [1] https://github.com/rockchip-linux/kernel/tree/develop-4.4 [2] https://github.com/rockchip-linux/kernel/commit/d1943fde81ff41d7cca87f4a42f03992e90bddd5 Cc: Zheng Yang <zhengyang@rock-chips.com> Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://patchwork.freedesktop.org/patch/msgid/HE1PR06MB4011D7B916CBF8B740ACC45FAC9B0@HE1PR06MB4011.eurprd06.prod.outlook.com
2019-10-09drm: two planes with the same zpos have undefined orderingSimon Ser
Currently the property docs don't specify whether it's okay for two planes to have the same zpos value and what user-space should expect in this case. The unspoken, legacy rule used in the past was to make user-space figure out the zpos from object IDs. However some drivers break this rule, that's why the ordering is documented as unspecified in case the zpos property is missing. User-space should rely on the zpos property only. There are some cases in which user-space might read identical zpos values for different planes. For instance, in case the property is mutable, user-space might set two planes' zpos to the same value. This is necessary to support user-space using the legacy DRM API where atomic commits are not possible: user-space needs to update the planes' zpos one by one. Because of this, user-space should handle multiple planes with the same zpos. While at it, remove the assumption that zpos is only for overlay planes. Additionally, update the drm_plane_state.zpos docs to clarify that zpos disambiguation via plane object IDs is a recommendation for drivers, not something user-space can rely on. In other words, when user-space sets the same zpos on two planes, drivers should rely on the plane object ID. v2: clarify drm_plane_state.zpos docs (Daniel) v3: zpos is for all planes (Marius, Daniel) v4: completely reword the drm_plane_state.zpos docs to make it clear the recommendation to use plane IDs is for drivers in case user-space uses duplicate zpos values (Pekka) v5: reword commit message (Pekka, James) v6: remove mention of Arm GPUs having planes which can't overlap, because this isn't uAPI yet (Daniel) Signed-off-by: Simon Ser <contact@emersion.fr> Reviewed-by: Pekka Paalanen <ppaalanen@gmail.com> Cc: Marius Vlad <marius.vlad@collabora.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: James Qian Wang <james.qian.wang@arm.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/T5nHrvXH0GKOp6ONaFHk-j2cwEb4_4C_sBz9rNw8mmPACuut-DQqC74HMAFKZH3_Q15E8a3YnmKCxap-djKA71VVZv_T-tFxaB0he13O7yA=@emersion.fr
2019-10-08drm: Add link training repeaters addressesRodrigo Siqueira
DP 1.3 specification introduces the Link Training-tunable PHY Repeater, and DP 1.4* supplemented it with new features. In the 1.4a spec, it was introduced some innovations to make handy to add support for systems with Thunderbolt or other repeater devices. It is important to highlight that DP specification had some updates from 1.3 through 1.4a. In particular, DP 1.4 defines Repeater_FEC_CAPABILITY at the address 0xf0004, and DP 1.4a redefined the address 0xf0004 to DP_MAX_LANE_COUNT_PHY_REPEATER. Changes since V4: - Update commit message - Fix misleading comments related to the spec version Changes since V3: - Replace spaces by tabs Changes since V2: - Drop the kernel-doc comment - Reorder LTTPR according to register offset Changes since V1: - Adjusts registers names to be aligned with spec and the rest of the file - Update spec comment from 1.4 to 1.4a Cc: Abdoulaye Berthe <Abdoulaye.Berthe@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Abdoulaye Berthe <Abdoulaye.Berthe@amd.com> Reviewed-by: Harry Wentland <Harry.Wentland@amd.com> Signed-off-by: Rodrigo Siqueira <rodrigosiqueiramelo@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190909212144.deeomlsqihwg4l3y@outlook.office365.com

There is finally no more users left in the kernel of drmP.h and drm_os_linux.h (drmP.h was the only user left). Delete the header files and delete the corresponding todo entry. When we started this quest there was more than 700 users of drmP.h. And drmP.h was a huge cover-it-all header file.
