The HVS block is supposed to fill the pixelvalve FIFOs fast enough to meet the requested framerate. The problem is, the HVS and memory bus bandwidths are limited, and if we don't take these limitations into account we might end up with HVS underflow errors. This patch is trying to model the per-plane HVS and memory bus bandwidth consumption and take a decision at atomic_check() time whether the estimated load will fit in the HVS and membus budget. Note that we take an extra margin on the memory bus consumption to let the system run smoothly when other blocks are doing heavy use of the memory bus. Same goes for the HVS limit, except the margin is smaller in this case, since the HVS is not used by external components. Signed-off-by:

The DP 1.4 spec defines the SDP header and SDP contents for a Picture Parameter Set (PPS) that must be sent in advance of DSC transmission to define the encoding characteristics. This was done in one struct, drm_dsc_pps_infoframe, which conatined the SDP header and PPS. Because the PPS is a property of DSC over any connector, not just DP, and because drm drivers may have their own SDP structs they wish to use, make the functions that initialise SDP and PPS headers take the components they operate on, not drm_dsc_pps_infoframe, Signed-off-by:

Native 420 and 422 transfer modes are new in DSC1.2 In these modes, each two pixels of a slice are treated as one pixel, so the slice width is half as large (round down) for the purposes of calucating the groups per line and chunk size in bytes In native 422 mode, each pixel has four components, so the mux component of a group is larger by one additional mux word and one additional component Now that there is native 422 support, the configuration option previously called enable422 is renamed to simple_422 to avoid confusion Acked-by:

This protects device resources from use after device removal. There are 3 ways for driver-device unbinding to happen: - The driver module is unloaded causing the driver to be unregistered. This can't happen as long as there are open file handles because a reference is taken on the module. - The device is removed (Device Tree overlay unloading). This can happen at any time. - The driver sysfs unbind file can be used to unbind the driver from the device. This can happen any time. v2: Since drm_atomic_helper_shutdown() has to be called after drm_dev_unplug() we don't want do block ->disable after unplug.

VI planes support coarse scaling which helps to overcome VI scaler limitations. While exact working of coarse scaling isn't known, it seems that it just skips programmed amount of rows and columns. This is especially useful for downscaling very big planes (4K down to 1080p). Horizontal coarse scaling is currently used to fit one line to VI scaler buffer. Vertical coarse scaling is used to assure that VI scaler is actually capable of processing framebuffer in one frame time. Signed-off-by:

After an event is sent, we try to copy it into the user buffer of the first waiter in drm_read() and if the user buffer doesn't have enough room we put it back onto the list. However, we didn't wake up any subsequent waiter, so that event may sit on the list until either a new vblank event is sent or a new waiter appears. Rare, but in the worst case may lead to a stuck process. Testcase: igt/drm_read/short-buffer-wakeup Signed-off-by:

If userspace has open fd(s) when drm_dev_unplug() is run, it will result in drm_dev_unregister() being called twice. First in drm_dev_unplug() and then later in drm_release() through the call to drm_put_dev(). Since userspace already holds a ref on drm_device through the drm_minor, it's not necessary to add extra ref counting based on no open file handles. Instead just drm_dev_put() unconditionally in drm_dev_unplug(). We now have this: - Userpace holds a ref on drm_device as long as there's open fd(s) - The driver holds a ref on drm_device as long as it's bound to the struct device When both sides are done with drm_device, it is released.

This patch attaches the colorspace connector property to the hdmi connector. Based on colorspace change, modeset will be triggered to switch to new colorspace. Based on colorspace property value create an infoframe with appropriate colorspace. This can be used to send an infoframe packet with proper colorspace value set which will help to enable wider color gamut like BT2020 on sink. This patch attaches and enables HDMI colorspace, DP will be taken care separately. v2: Merged the changes of creating infoframe as well to this patch as per Maarten's suggestion. v3: Addressed review comments from Shashank. Separated HDMI and DP colorspaces as suggested by Ville and Maarten. v4: Addressed Chris and Ville's review comments, and created a common colorspace property for DP and HDMI, filtered the list based on the colorspaces supported by the respective protocol standard. Handle the default case properly. v5: Merged the DP handling along with platform colorspace handling as per Shashank's comments. v6: Reverted to old design of exposing all colorspaces to userspace as per Ville's review comment v7: Fixed a checkpatch complaint, Addressed Maarten' review comment, updated the RB from Maarten and Jani's ack. v8: Moved colorspace AVI Infoframe programming to drm core and removed from driver as per Ville's suggestion. v9: Added a check to only allow RGB colorpsaces to be set in infoframe though the colorspace property. Since there is no output csc property to control planar formats and it will be added later. Changes for RGB->YUV conversion inside driver without userspace knowledge is still supported. This is as per Ville's suggestion. v10: Fixed an error in if check. v11: Dropped the check for planar vs RGB and allow all the colorspaces. Onus will be on userspace to pick whatever pipe output it is able to drive. v12: Added Ville's RB. Signed-off-by:
