DisplayID blocks allow embedding of CEA blocks. The payloads are identical to traditional top level CEA extension blocks, but the header is slightly different. This change allows the CEA parser to find a CEA block inside a DisplayID block. Additionally, it adds support for parsing the embedded CTA header. No further changes are necessary due to payload parity. This change fixes audio support for the Valve Index HMD. Signed-off-by:

Komeda interrupts may be shared with other hardware blocks. One needs to use devm_request_irq() with IRQF_SHARED to create a shared interrupt handler. As a result of not using drm_irq_install() api, one needs to set "(struct drm_device *)->irq_enabled = true/false" to enable/disable vblank interrupts. Changes from v1:- 1. Squashed the following two patches into one (as the second patch is a consequence of the first one):- drm/komeda: Avoid using DRIVER_IRQ_SHARED drm/komeda: Enable/Disable vblank interrupts 2. Fixed the commit message (as pointed by Daniel Vetter) 3. Removed calls to 'drm_irq_uninstall()' as we are no longer using drm_irq_install() 4. Removed the struct member 'komeda_kms_driver.irq_handler' as it is not used anywhere. Signed-off-by:

clang points out a bug in the clock calculation on 32-bit, that leads to the clock_ratio always being zero: drivers/gpu/drm/arm/display/komeda/komeda_crtc.c:31:36: error: shift count >= width of type [-Werror,-Wshift-count-overflow] aclk = komeda_calc_aclk(kcrtc_st) << 32; Move the shift into the division to make it apply on a 64-bit variable. Also use the more expensive div64_u64() instead of div_u64() to account for pxlclk being a 64-bit integer.

Add a KMS driver for the Ingenic JZ47xx family of SoCs. This driver is meant to replace the aging jz4740-fb driver. This driver does not make use of the simple pipe helper, for the reason that it will soon be updated to support more advanced features like multiple planes, IPU integration for colorspace conversion and up/down scaling, support for DSI displays, and TV-out and HDMI outputs. Notes: v2: - Remove custom handling of panel. The panel is now discovered using the standard API. - Lots of small tweaks suggested by upstream v3: - Use devm_drm_dev_init() - Update compatible strings to -lcd instead of -drm - Add destroy() callbacks to plane and crtc - The ingenic,lcd-mode is now read from the bridge's DT node v4: Remove ingenic,lcd-mode property completely. The various modes are now deduced from the connector type, the pixel format or the bus flags. v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers - Use 32bpp framebuffer instead of 16bpp, as it'll work with both 16-bit and 24-bit panel - Get rid of drm_format_plane_cpp() which has been dropped upstream - Avoid using drm_format_info->depth, which is deprecated.

The idea behind keeping the saturation mask local to a context backfired spectacularly. The premise with the local mask was that we would be more proactive in attempting to use semaphores after each time the context idled, and that all new contexts would attempt to use semaphores ignoring the current state of the system. This turns out to be horribly optimistic. If the system state is still oversaturated and the existing workloads have all stopped using semaphores, the new workloads would attempt to use semaphores and be deprioritised behind real work. The new contexts would not switch off using semaphores until their initial batch of low priority work had completed. Given sufficient backload load of equal user priority, this would completely starve the new work of any GPU time. To compensate, remove the local tracking in favour of keeping it as global state on the engine -- once the system is saturated and semaphores are disabled, everyone stops attempting to use semaphores until the system is idle again. One of the reason for preferring local context tracking was that it worked with virtual engines, so for switching to global state we could either do a complete check of all the virtual siblings or simply disable semaphores for those requests. This takes the simpler approach of disabling semaphores on virtual engines. The downside is that the decision that the engine is saturated is a local measure -- we are only checking whether or not this context was scheduled in a timely fashion, it may be legitimately delayed due to user priorities. We still have the same dilemma though, that we do not want to employ the semaphore poll unless it will be used. v2: Explain why we need to assume the worst wrt virtual engines.

Writeback split is also for workaround the size limitation of d71 scaler. Like layer_split, writeback downscaling also can use two scalers to handle the scaling half-by-half. The only differnence is writback needs a standalone component (splitter)'s help to split the composition result.

Komeda supports two types of layer split: - none-scaling split - scaling split Since D71 merger only support scaler as input, so for none-scaling split, the two layer dflow will be output to compiz directly. for scaling_split, the data flow will be merged by merger firstly, then output the merged data flow to compiz.

- Creates the zpos property. - Implement komeda_crtc_normalize_zpos to replace drm_atomic_normalize_zpos, reasons as the following: 1. The drm_atomic_normalize_zpos allows to configure same zpos for different planes, but komeda doesn't support such configuration. 2. For further slave pipline case, Komeda need to calculate the max_slave_zorder, we will merge such calculation into komed_crtc_normalize_zpos to save a separated plane_state loop. 3. For feature none-scaling layer_split, which a plane_state will be assigned to two individual layers(left/right), which requires two normalize_zpos for this plane, plane_st->normalize_zpos will be used by left layer, normalize_zpos + 1 for right_layer.
