2018-05-11drm: Expose modes with aspect ratio, only if requestedAnkit Nautiyal
We parse the EDID and add all the modes in the connector's modelist. This adds CEA modes with aspect ratio information too, regardless of whether user space requested this information or not. This patch: -prunes the modes with aspect-ratio information, from the drm_mode_get_connector modelist supplied to the user, if the user-space has not set the aspect ratio DRM client cap. However if such a mode is unique in the list, it is kept in the list, with aspect-ratio flags reset. -prepares a list of exposed modes, which is used to find unique modes if aspect-ratio is not allowed. -adds a new list_head 'exposed_head' in drm_mode_display, to traverse the list of exposed modes.

Instead of straight away pruning such a mode, the mode is retained with aspect ratio bits set to zero, provided it is unique. V4: rebase V5: Addressed review comments from Ville: -used a pointer to store last valid mode. -avoided, modifying of picture_aspect_ratio in kernel mode, instead only flags bits of user mode are reset (if aspect-ratio is not supported). V6: As suggested by Ville, corrected the mode pruning logic and elaborated the mode pruning logic and the assumptions taken. V7: rebase V8: rebase V9: rebase V10: rebase V11: Fixed the issue caused in kms_3d test, and enhanced the pruning logic to correctly identify and prune modes with aspect-ratio, if aspect-ratio cap is not set. V12: As suggested by Ville, added another list_head in drm_mode_display to traverse the list of exposed modes and avoided duplication of modes. V13: Minor modifications, as suggested by Ville. v14: As suggested by Daniel Vetter and Ville Syrjala, corrected the pruning logic to avoid any dependency in the order of mode with aspect-ratio.

2018-05-11drm: Add DRM client cap for aspect-ratioAnkit Nautiyal
To enable aspect-ratio support in DRM, blindly exposing the aspect ratio information along with mode, can break things in existing non-atomic user-spaces which have no intention or support to use this aspect ratio information. To avoid this, a new drm client cap is required to enable a non-atomic user-space to advertise if it supports modes with aspect-ratio. Based on this cap value, the kernel will take a call on exposing the aspect ratio info in modes or not. This patch adds the client cap for aspect-ratio. Since no atomic-userspaces blow up on receiving aspect-ratio information, the client cap for aspect-ratio is always enabled for atomic clients.

2018-05-08drm/dp: Correctly mask DP_TRAINING_AUX_RD_INTERVAL values for DP 1.4Matt Atwood
DP_TRAINING_AUX_RD_INTERVAL with DP 1.3 spec changed bit scheeme from 8 bits to 7 in DPCD 0x000e. The 8th bit is used to identify extended receiver capabilities. For panels that use this new feature wait interval would be increased by 512 ms, when spec is max 16 ms. This behavior is described in table 2-158 of DP 1.4 spec address 0000eh. With the introduction of DP 1.4 spec main link clock recovery was standardized to 100 us regardless of TRAINING_AUX_RD_INTERVAL value. To avoid breaking panels that are not spec compiant we now warn on invalid values. V2: commit title/message, masking all 7 bits, warn on out of spec values. V3: commit message, make link train clock recovery follow DP 1.4 spec.

2018-05-04drm/rect: Handle rounding errors in drm_rect_clip_scaled, v3.Maarten Lankhorst
Instead of relying on a scale which may increase rounding errors, clip src by doing: src * (dst - clip) / dst and rounding the result away from 1, so the new coordinates get closer to 1. We won't need to fix up with a magic macro afterwards, because our scaling factor will never go to the other side of 1. Changes since v1: - Adjust dst immediately, else drm_rect_width/height on dst gives bogus results. Change since v2: - Get rid of macros and use 64-bits math.

Note that a pile of drivers don't seem to take implicit fencing into account, or at least don't call drm_atoimc_set_fence_for_plane(). Cc'ing relevant people, or at least some. Some drivers also look like they don't disable implicit fencing (e.g. amdgpu) because the explicit fences and implicit fences are handled by entirely independent code paths. I also wonder whether we shouldn't just make the recommended helpers the default ones, since a lot of drivers don't bother to handle the implicit fences at all it seems.

mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the bowels of the .atomic_enable() hook. That prevents us from taking the plane mutex in fb->dirty() unless we also plumb down the acquire context. Instead it seems simpler to split the fb->dirty() into a tinydrm specific lower level hook that can be called from mipi_dbi_enable_flush() and from a generic higher level tinydrm_fb_dirty() helper.

2018-03-19drm: Reduce object size of DRM_DEV_<LEVEL> usesJoe Perches
These macros are similar to the DRM_<LEVEL> with the addition of a struct device * to the arguments. Convert the single drm_dev_printk function into 2 separate functions. drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg for conditional masked use. Remove the __func__ argument and use __builtin_return_address(0) to be similar to the DRM_<LEVEL> macros uses. Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments and use a consistent style. These macros are rarely used in the generic gpu/drm code so the code size does not change much for a defconfig, but when more drivers are enabled, there is ~4k savings. Many of these macros have no existing use at all. $ size -t drivers/gpu/drm/built-in.a | tail -1 1877530 44651 995 1923176 1d5868 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 1877527 44651 995 1923173 1d5865 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17166750 2689238 108352 19964340 130a1b4 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17168888 2691734 108352 19968974 130b3ce (TOTALS) Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/e5c164946e15375ac71b69b75f296efdf0b76e6d.1521233717.git.joe@perches.com

2018-03-16Revert "drm: Use a flexible array member for blob property data"Ville Syrjälä
Using a flexible array for the blob data was a mistake by me. It forces all users of the blob data to cast blob->data to something else. void* is clearly superior so let's go back to the original scheme. Not a clean revert as the code has moved.
