When using a 24-bit panel on a 8-bit serial bus, the pixel clock requested by the panel has to be multiplied by 3, since the subpixels are shifted sequentially. The code (in ingenic_drm_encoder_atomic_check) already computed crtc_state->adjusted_mode->crtc_clock accordingly, but clk_set_rate() used crtc_state->adjusted_mode->clock instead.

The drm_format_info() function returns NULL if the format is unsupported, but the simplefb_get_validated_format() is expected to return error pointers. If we propagate the NULL return then it will lead to a NULL dereference in the callers. Swap the NULL and trade it in for an ERR_PTR(-EINVAL).

In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. After that, the error code -ENOMEM should be returned. Reported-by:

The allocation of fifo is lacking an allocation failure check, so fix this by adding one. In the case where fifo->static_buffer fails to be allocated the error return path neglects to kfree the fifo object. Fix this by adding in the missing kfree.

GPUs with more than a single regulator (e.g. G72 on MT8183) will require platform-specific handling for devfreq, for 2 reasons: 1. The opp core (drivers/opp/core.c:_generic_set_opp_regulator) does not support multiple regulators, so we'll need custom handlers. 2. Generally, platforms with 2 regulators have platform-specific constraints on how the voltages should be set (e.g. minimum/maximum voltage difference between them), so we should not just create generic handlers that simply change the voltages without taking care of those constraints. Disable devfreq for now on those GPUs. Signed-off-by: -

It's very confusing for userspace to have to deal with inconsistencies here, and some drivers screwed this up a bit. Most just ommitted the format list when they meant to say that only linear modifier is allowed, but some also meant that only implied modifiers are acceptable (because actually none of the planes registered supported modifiers). Now that this is all done consistently across all drivers, document the rules and enforce it in the drm core. v2: - Make the capability a link (Simon) - Note that all is lost before 5.1. v3: - Use drm_WARN_ON (Lyude) Acked-by:

This change fixes all of the arm64 issues we've had in the driver. ARM support is provided in svga version 3, for which support we've added in previous changes. svga version 3 currently lacks many of the advanced features (in particular 3D support is lacking) but that will change in time.

SVGA3 is the next version of our PCI device. Some of the changes include using MMIO for register accesses instead of ioports, deprecating the FIFO MMIO and removing a lot of the old and legacy functionality.

Now since Christian reworked TTM to always keep objects on the LRU list unless they are pinned we shouldn't need the reservation semaphore.

In cases where the dirty linear memory range spans multiple sample sheets in a surface, the dirty surface region is incorrectly computed. To do this correctly and in an optimized fashion we would have to compute the dirty region of each sample sheet and compute the union of those regions. But assuming that cpu writing to a multisample surface is rather a corner case than a common case, just set the dirty region to the full surface.

SVGA_REG_ENABLE is a register name, and SVGA_REG_ENABLE_(ENABLE| DISABLE|HIDE) are its valid values. We were incorrectly setting the register value to itself. This happened to work because the SVGA_REG_ENABLE is happens to to be the same value as SVGA_REG_ENABLE_ENABLE, but is still semantically incorrect. Lets use the correct enum when setting SVGA_REG_ENABLE. Signed-off-by:

Ville pointed this out to me when fixing some issues in drm_dp_read_downstream_info() - the DPCD version check here is bogus as there's no DisplayPort versions prior to 1.0. The original code from i915 that this was extracted from actually did: dpcd[DP_DPCD_REV] == DP_DPCD_REV_10 Which is correct, and somehow got missed when extracting this function. So let's fix this. Note that as far as I'm aware, I don't think this fixes any actual issues users are hitting. Signed-off-by:
