2021-04-08drm/syncobj: use newly allocated stub fencesDavid Stevens3-7/+46
Allocate a new private stub fence in drm_syncobj_assign_null_handle, instead of using a static stub fence. When userspace creates a fence with DRM_SYNCOBJ_CREATE_SIGNALED or when userspace signals a fence via DRM_IOCTL_SYNCOBJ_SIGNAL, the timestamp obtained when the fence is exported and queried with SYNC_IOC_FILE_INFO should match when the fence's status was changed from the perspective of userspace, which is during the respective ioctl. When a static stub fence started being used in by these ioctls, this behavior changed. Instead, the timestamp returned by SYNC_IOC_FILE_INFO became the first time anything used the static stub fence, which has no meaning to userspace.

2021-04-01drm/vblank: Do not store a new vblank timestamp in drm_vblank_restore()Ville Syrjälä1-1/+2
drm_vblank_restore() exists because certain power saving states can clobber the hardware frame counter. The way it does this is by guesstimating how many frames were missed purely based on the difference between the last stored timestamp vs. a newly sampled timestamp. If we should call this function before a full frame has elapsed since we sampled the last timestamp we would end up with a possibly slightly different timestamp value for the same frame. Currently we will happily overwrite the already stored timestamp for the frame with the new value. This could cause userspace to observe two different timestamps for the same frame (and the timestamp could even go backwards depending on how much error we introduce when correcting the timestamp based on the scanout position). To avoid that let's not update the stored timestamp at all, and instead we just fix up the last recorded hw vblank counter value such that the already stored timestamp/seq number will match. Thus the next time a vblank irq happens it will calculate the correct diff between the current and stored hw vblank counter values. Sidenote: Another possible idea that came to mind would be to do this correction only if the power really was removed since the last time we sampled the hw frame counter. But to do that we would need a robust way to detect when it has occurred. Some possibilities could involve some kind of hardare power well transition counter, or potentially we could store a magic value in a scratch register that lives in the same power well. But I'm not sure either of those exist, so would need an actual investigation to find out. All of that is very hardware specific of course, so would have to be done in the driver code.

2021-04-01drm: Refuse to create zero width/height cmdline modesVille Syrjälä1-0/+3
If the user specifies zero width/height cmdline mode i915 will blow up as the fbdev path will bypass the regular fb sanity check that would otherwise have refused to create a framebuffer with zero width/height. The reason I thought to try this is so that I can force a specific depth for fbdev without actually having to hardcode the mode on the kernel cmdline. Eg. if I pass video=0x0-8 I will get an 8bpp framebuffer at my monitor's native resolution.

2021-03-31drm/displayid: add new displayid section/block iteratorsJani Nikula2-0/+92
Iterating DisplayID blocks across sections (in EDID extensions) is unnecessarily complicated for the caller. Implement DisplayID iterators to go through all blocks in all sections. Usage example: const struct displayid_block *block; struct displayid_iter iter; displayid_iter_edid_begin(edid, &iter); displayid_iter_for_each(block, &iter) { /* operate on block */ } displayid_iter_end(&iter); When DisplayID is stored in EDID extensions, the DisplayID sections map to extensions as described in VESA DisplayID v1.3 Appendix B: DisplayID as an EDID Extension. This is implemented here. When DisplayID is stored in its dedicated DDC device 0xA4, according to VESA E-DDC v1.3, different rules apply for the structure. This is not implemented here, as we don't currently use it, but the idea is you'd have a different call for beginning the iteration, for example simply: displayid_iter_begin(displayid, &iter); instead of displayid_iter_edid_begin(), and everything else would be hidden away in the iterator functions. v2: - sizeof(struct displayid_block) -> sizeof(*block) (Ville) - remove __ prefix from displayid_iter_block Reviewed-by: Ville Syrjälä <[email protected]> Signed-off-by: Jani Nikula <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/da3dead1752ab16c061f7bd248ac1a4268f7fefb.1617024940.git.jani.nikula@intel.com

2021-03-24drm/tilcdc: fix pixel clock setting warning messageDario Binacchi1-5/+5
The warning message did not printed the LCD pixel clock rate but the LCD clock divisor input rate. As a consequence, the required and real pixel clock rates are now passed to the tilcdc_pclk_diff().

2021-03-24drm/tilcdc: fix LCD pixel clock settingDario Binacchi1-2/+3
The tilcdc_pclk_diff() compares the requested pixel clock rate to the real one, so passing it clk_rate instead of clk_rate / clkdiv caused it to fail even if the clk_rate was properly set. Adding the real_pclk_rate variable makes the code more readable.

2021-03-24drm/tilcdc: rename req_rate to pclk_rateDario Binacchi1-6/+6
The req_rate name is a little misleading, so let's rename to pclk_rate (pixel clock rate).

2021-03-24drm/rockchip: Remove unused variableMaxime Ripard1-2/+0
Commit 977697e20b3d ("drm/atomic: Pass the full state to planes atomic disable and update") added the old_state variable instead of what used to be a parameter, but it also removed the sole user of that variable in the vop_plane_atomic_update function leading to an usused variable. Remove it.
