On the vc4 devices (and later), the blending is done by a single device called the HVS. The HVS has three FIFO that can operate in parallel, and route their output to 6 CRTCs and 7 encoders on the BCM2711. Each of these CRTCs and encoders have some constraints on which FIFO they can feed from, so we need some code to take all those constraints into account and assign FIFOs to CRTCs. The problem can be simplified by assigning those FIFOs to CRTCs by ascending output index number. We had a comment mentioning it already, but we were never actually enforcing it. It was working still in most situations because the probe order is roughly equivalent, except for the (optional, and fairly rarely used on the Pi4) VEC which was last in the probe order sequence, but one of the earliest device to assign. This resulted in configurations that were rejected by our code but were still valid with a different assignment. We can fix this by making sure we assign CRTCs to FIFOs by ordering them by ascending HVS output index. Fixes: 87ebcd42 ("drm/vc4: crtc: Assign output to channel automatically") Reviewed-by:

If no preferred value for bits-per-pixel has been given, fall back to 32. Never use the preferred depth. The color depth is the number of color/alpha bits per pixel, while bpp is the overall number of bits in most cases. Most noteworthy, XRGB8888 has a depth of 24 and a bpp value of 32. Using depth for bpp would make the value 24 as well and format selection in fbdev helpers fails. Unfortunately XRGB8888 is the most common format and the old heuristic therefore fails for most of the drivers (unless they implement the 24-bit RGB888 format). Picking a bpp of 32 will later on result in a default depth of 24 and the format XRGB8888. As XRGB8888 is the default format for most of the current and legacy graphics stack, all drivers must support it. So it is the safe choice. v2: * fix commit-message typo (Javier) Signed-off-by:

Set the preferred depth from the format of the scanout buffer. The value cannot be hardcoded, as the scanout buffer is only known at runtime. Keeping the existing switch statement just duplicates the driver's existing logic for format detection.

Add support for the following composite output modes (all of them are somewhat more obscure than the previously defined ones): - NTSC_443 - NTSC-style signal with the chroma subcarrier shifted to 4.43361875 MHz (the PAL subcarrier frequency). Never used for broadcasting, but sometimes used as a hack to play NTSC content in PAL regions (e.g. on VCRs). - PAL_N - PAL with alternative chroma subcarrier frequency, 3.58205625 MHz. Used as a broadcast standard in Argentina, Paraguay and Uruguay to fit 576i50 with colour in 6 MHz channel raster. - PAL60 - 480i60 signal with PAL-style color at normal European PAL frequency. Another non-standard, non-broadcast mode, used in similar contexts as NTSC_443. Some displays support one but not the other. - SECAM - French frequency-modulated analog color standard; also have been broadcast in Eastern Europe and various parts of Africa and Asia. Uses the same 576i50 timings as PAL. Also added some comments explaining color subcarrier frequency registers. Acked-by:

Now that the core can deal fine with analog TV modes, let's convert the vc4 VEC driver to leverage those new features. We've added some backward compatibility to support the old TV mode property and translate it into the new TV norm property.

Most of the TV connectors will need a similar get_modes implementation that will, depending on the drivers' capabilities, register the 480i and 576i modes. That implementation will also need to set the preferred flag and order the modes based on the driver and users preferrence. This is especially important to guarantee that a userspace stack such as Xorg can start and pick up the preferred mode while maintaining a working output. Signed-off-by:

Now that we can easily extend the named modes list, let's add a few more analog TV modes that were used in the wild, and some unit tests to make sure it works as intended. Reviewed-by:
-
Maxime Ripard authored
Commit 3aeeb13d ("drm/modes: Support modes names on the command line") initially introduced the named modes support by essentially matching the name passed on the command-line to the mode names defined by the drivers. This proved to be difficult to work with, since all drivers had to provide properly named modes. This was also needed because we weren't passing a full blown-mode to the drivers, but were only filling its name. Thanks to the previous patches, we now generate a proper mode, and we thus can use the usual matching algo on timings, and can simply drop the name match. Reviewed-by:

The framework will get the drm_display_mode from the drm_cmdline_mode it got by parsing the video command line argument by calling drm_connector_pick_cmdline_mode(). The heavy lifting will then be done by the drm_mode_create_from_cmdline_mode() function. In the case of the named modes though, there's no real code to make that translation and we rely on the drivers to guess which actual display mode we meant. Let's modify drm_mode_create_from_cmdline_mode() to properly generate the drm_display_mode we mean when passing a named mode. Reviewed-by:

Our new tv mode option allows to specify the TV mode from a property. However, it can still be useful, for example to avoid any boot time artifact, to set that property directly from the kernel command line. Let's add some code to allow it, and some unit tests to exercise that code. Reviewed-by:

As part of the command line parsing rework coming in the next patches, we'll need to lookup drm_connector_tv_mode values by their name, already defined in drm_tv_mode_enum_list. In order to avoid any code duplication, let's do a function that will perform a lookup of a TV mode name and return its value. Reviewed-by:

Multiple drivers (meson, vc4, sun4i) define analog TV 525-lines and 625-lines modes in their drivers. Since those modes are fairly standard, and that we'll need to use them in more places in the future, it makes sense to move their definition into the core framework. However, analog display usually have fairly loose timings requirements, the only discrete parameters being the total number of lines and pixel clock frequency. Thus, we created a function that will create a display mode from the standard, the pixel frequency and the active area. Tested-by:

The TV mode property has been around for a while now to select and get the current TV mode output on an analog TV connector. Despite that property name being generic, its content isn't and has been driver-specific which makes it hard to build any generic behaviour on top of it, both in kernel and user-space. Let's create a new enum tv norm property, that can contain any of the analog TV standards currently supported by kernel drivers. Each driver can then pass in a bitmask of the modes it supports, and the property creation function will filter out the modes not supported. We'll then be able to phase out the older tv mode property. Tested-by:

drm_mode_create_tv_properties(), among other things, will create the "mode" property that stores the analog TV mode that connector is supposed to output.

The current tv_mode has driver-specific values that don't allow to easily share code using it, either at the userspace or kernel level.

As of commit eae06120 ("drm: refuse ADDFB2 ioctl for broken bigendian drivers"), drivers must set the quirk_addfb_prefer_host_byte_order quirk to make the drm_mode_addfb() compat code work correctly on big-endian machines. While that works fine for big-endian XRGB8888 and ARGB8888, which are mapped to the existing little-endian BGRX8888 and BGRA8888 formats, it does not work for big-endian XRGB1555 and RGB565, as the latter are not listed in the format database. Fix this by adding the missing formats. Limit this to big-endian platforms, as there is currently no need to support these formats on little-endian platforms.

The drm_sched_entity_kill() is invoked twice by drm_sched_entity_destroy() while userspace process is exiting or being killed. First time it's invoked when sched entity is flushed and second time when entity is released. This causes a lockup within wait_for_completion(entity_idle) due to how completion API works. Calling wait_for_completion() more times than complete() was invoked is a error condition that causes lockup because completion internally uses counter for complete/wait calls. The complete_all() must be used instead in such cases. This patch fixes lockup of Panfrost driver that is reproducible by killing any application in a middle of 3d drawing operation.
