The hardware settings for color format and pitch are state of the primary plane. Store the values in the primary plane's state structure struct cirrus_primary_plane_state. Adapt all callers. All fields in struct cirrus_device are now considered immutable after initialization. Plane updates consider the difference between the old and the new plane state before updating format or pitch.

Test a display mode against the available amount of video memory in struct drm_mode_config_funcs.mode_valid, which cirrus implements in cirrus_mode_config_mode_valid(). This helper tests display modes against device-wide limits. Remove the now-obsolete per-CRTC test. Signed-off-by:

Thomas Zimmermann authored
Enable damage clipping on the primary plane and iterate over small areas of reported framebuffer damage. Avoid the overhead of permanent full-screen updates that cirrus currently implements. This problem is indicated by the warning drm_plane_enable_fb_damage_clips() not called in the kernel's log. Without damage clipping, drivers do full updates of the screen area. This is costly as many screen updates, such as cursor movement or command-line input, only change a small portion of the output. Damage clipping allows renderers to inform drivers about the changed areas. With the damage information known, cirrus now iterates over a list of change areas and only flushes those to the hardware's scanout buffer. Signed-off-by:

Replace simple-KMS helpers with DRM's regular helpers for atomic modesetting. Avoids the mid-layer and the additional wrappers around GEM's shadow-plane helpers. Most of the simple-KMS code is just wrappers around regular atomic helpers. The conversion is therefore equivalent to pulling the simple-KMS helpers into cirrus and removing all the intermediate code and data structures between the driver and the atomic helpers. As the simple-KMS helpers lump primary plan, CRTC and encoder into a single data structure, the conversion to regular helpers allows to split modesetting from plane updates and handle each individually.

Thomas Zimmermann authored
The calculation for the scanout-buffer blit offset is independent from the color format. In the one case where the current code uses fb->pitches[0] instead of cirrus->pitch, their values are identical. Hence merge all into a single line. Signed-off-by:

There are DRM fourcc formats that have pixels smaller than a byte, but the conversion_buf_size() function assumes that pixels are a multiple of bytes and use the struct drm_format_info .cpp field to calculate the dst_pitch. Instead, calculate it by using the bits per pixel (bpp) and divide it by 8 to account for formats that have sub-byte pixels. Signed-off-by:

The Rockchip PLL drivers are currently table based and support only the most common pixelclocks. Discard all modes we cannot achieve at all. Normally the desired pixelclocks have an exact match in the PLL driver, nevertheless allow for a 0.1% error just in case. Tested-by:

The driver checks if the pixel clock of the given mode matches an entry in the mpll config table. At least for the Synopsys phy the frequencies in the mpll table are meant as a frequency range up to which the entry works, not as a frequency that must match the pixel clock. Return MODE_OK when the pixelclock is smaller than one of the mpll frequencies to allow for more display resolutions. Limit this behaviour to the Synopsys phy at the moment and keep the current behaviour of forcing exact pixelclock rates for the other phys until it has been sorted out how and if the vendor specific phys work with non standard clock rates.

The different VOP variants support different maximum resolutions. Reject resolutions that are not supported by a specific variant. This hasn't been a problem in the upstream driver so far as 1920x1080 has been the maximum resolution supported by the HDMI driver and that resolution is supported by all VOP variants. Now with higher resolutions supported in the HDMI driver we have to limit the resolutions to the ones supported by the VOP. The actual maximum resolutions are taken from the Rockchip downstream Kernel. Signed-off-by:

Add support for the Sony TD4353 JDI 2160x1080 display panel used in some Sony Xperia XZ2 and XZ2 Compact smartphones. Due to the specifics of smartphone manufacturing, it is impossible to retrieve a better name for this panel. This revision adds support for the default 60 Hz configuration, however there could possibly be some room for expansion, as the display panels used on Sony devices have historically been capable of >2x refresh rate overclocking.

VirtIO-GPU got a new config option for disabling KMS. There were two problems left unnoticed during review when the new option was added: 1. The IS_ENABLED(CONFIG_DRM_VIRTIO_GPU_KMS) check in the code was inverted, hence KMS was disabled when it should be enabled and vice versa. 2. The disabled KMS crashed kernel with a NULL dereference in drm_kms_helper_hotplug_event(), which shall not be invoked with a disabled KMS. Fix the inverted config option check in the code and skip handling the VIRTIO_GPU_EVENT_DISPLAY sent by host when KMS is disabled in guest to fix the crash. Acked-by:
