2023-01-16drm/msm/gpu: Add default devfreq thresholdsRob Clark1-0/+9
Setup more appropriate devfreq tuning thresholds. Signed-off-by: Rob Clark <robdclark@chromium.org> Patchwork: https://patchwork.freedesktop.org/patch/517788/ Link: https://lore.kernel.org/r/20230110231447.1939101-4-robdclark@gmail.com Reviewed-by: Chia-I Wu <olvaffe@gmail.com>
2023-01-16drm/msm/gpu: Bypass PM QoS constraint for idle clampRob Clark2-82/+65
Change idle freq clamping back to the direct method, bypassing PM QoS requests. The problem with using PM QoS requests is they call (indirectly) the governors ->get_target_freq() which goes thru a get_dev_status() cycle. The problem comes when the GPU becomes active again and we remove the idle-clamp request, we go through another get_dev_status() cycle for the period that the GPU has been idle, which triggers the governor to lower the target freq excessively. This partially reverts commit 7c0ffcd40b16 ("drm/msm/gpu: Respect PM QoS constraints"), but preserves the use of boost QoS request, so that it will continue to play nicely with other QoS requests such as a cooling device. This also mostly undoes commit 78f815c1cf8f ("drm/msm: return the average load over the polling period") Signed-off-by: Rob Clark <robdclark@chromium.org> Patchwork: https://patchwork.freedesktop.org/patch/517785/ Link: https://lore.kernel.org/r/20230110231447.1939101-3-robdclark@gmail.com Reviewed-by: Chia-I Wu <olvaffe@gmail.com>

2023-01-12drm/msm/dpu: Reject topologies for which no DSC blocks are availableMarijn Suijten1-0/+5
Resource allocation of DSC blocks should behave more like LMs and CTLs where NULL resources (based on initial hw_blk creation via definitions in the catalog) are skipped ^1. The current hardcoded mapping of DSC blocks however means that resource allocation shouldn't succeed at all when the DSC block on the corresponding index doesn't exist, rather than searching for the next free block. This hardcoded mapping should be loosened separately as DPU 5.0.0 introduced a crossbar where DSC blocks can be "somewhat" freely bound to any PP and CTL (in proper pairs). ^1: which, on hardware that supports DSC, can happen after a git rebase ended up moving additions to _dpu_cfg to a different struct which has the same patch context.

2023-01-12drm/msm/dsi: Flip greater-than check for slice_count and slice_per_intfMarijn Suijten1-2/+3
According to downstream /and the comment copied from it/ this comparison should be the other way around. In other words, when the panel driver requests to use more slices per packet than what could be sent over this interface, it is bumped down to only use a single slice per packet (and strangely not the number of slices that could fit on the interface).

2023-01-12drm/msm/dsi: Use DSC slice(s) packet size to compute word countMarijn Suijten1-1/+1
According to downstream the value to use for WORD_COUNT is bytes_per_pkt, which denotes the number of bytes in a packet based on how many slices have been configured by the panel driver times the width of a slice times the number of bytes per pixel. The DSC panels seen thus far use one byte per pixel, only one slice per packet, and a slice width of half the panel width leading to the desired bytes_per_pkt+1 value to be equal to hdisplay/2+1. This however isn't the case anymore for panels that configure two slices per packet, where the value should now be hdisplay+1. Note that the aforementioned panel (on a Sony Xperia XZ3, sdm845) with slice_count=1 has also been tested to successfully accept slice_count=2, which would have shown corrupted output previously.

2023-01-09drm/msm/dp: Implement hpd_notify()Bjorn Andersson3-0/+25
The DisplayPort controller's hot-plug mechanism is based on pinmuxing a physical signal on a GPIO pin into the controller. This is not always possible, either because there aren't dedicated GPIOs available or because the hot-plug signal is a virtual notification, in cases such as USB Type-C. For these cases, by implementing the hpd_notify() callback for the DisplayPort controller's drm_bridge, a downstream drm_bridge (next_bridge) can be used to track and signal the connection status changes. This makes it possible to use downstream drm_bridges such as display-connector or any virtual mechanism, as long as they are implemented as a drm_bridge.

2023-01-09drm/msm/dp: Rely on hpd_enable/disable callbacksBjorn Andersson4-10/+35
The DisplayPort controller's internal HPD interrupt handling is used for cases where the HPD signal is connected to a GPIO which is pinmuxed into the DisplayPort controller. In other configurations the HPD notification might be delivered by the DRM framework from an associated bridge. This difference is not appropriately represented by the "is_edp" boolean, but is properly represented by the frameworks invocation of the hpd_enable() and hpd_disable() callbacks. Switch the current condition to rely on these callbacks instead. This ensures appropriate handling of the three cases; no bridge connected, a bridge without DRM_BRIDGE_OP_HPD and a bridge with DRM_BRIDGE_OP_HPD.
