2022-07-05drm/msm: Expose client engine utilization via fdinfoRob Clark
Similar to AMD commit 874442541133 ("drm/amdgpu: Add show_fdinfo() interface"), using the infrastructure added in previous patches, we add basic client info and GPU engine utilisation for msm.

2022-07-04drm: bridge: sii8620: fix possible off-by-oneHangyu Hua
The next call to sii8620_burst_get_tx_buf will result in off-by-one When ctx->burst.tx_count + size == ARRAY_SIZE(ctx->burst.tx_buf). The same thing happens in sii8620_burst_get_rx_buf. This patch also change tx_count and tx_buf to rx_count and rx_buf in sii8620_burst_get_rx_buf. It is unreasonable to check tx_buf's size and use rx_buf.

The MSM HDMI driver has support for hpd_regs on 8x74/8084: supply regulators that are to be enabled for HPD to work. Currently these regulators contain the hpd_gdsc, which was replaced by the power-domains support and hpd-5v/hpd-5v-en, which are not used by the chip itself. They power up the ESD bridge.

Writeback block for sm8250 was using the default maxlinewidth of 2048. But this is not right as it supports upto 4096. This should have no effect on most resolutions as we are still limiting upto maxlinewidth of SSPP for adding the modes.

2022-07-04drm/msm/dpu: move intf and wb assignment to dpu_encoder_setup_display()Abhinav Kumar
intf and wb resources are not dependent on the rm global state so need not be allocated during dpu_encoder_virt_atomic_mode_set(). Move the allocation of intf and wb resources to dpu_encoder_setup_display() so that we can utilize the hw caps even during atomic_check() phase. Since dpu_encoder_setup_display() already has protection against setting invalid intf_idx and wb_idx, these checks can now be dropped as well. changes in v2: - add phys->hw_intf and phys->hw_wb checks back changes in v3: - correct the Fixes tag Fixes: e02a559a720f ("drm/msm/dpu: make changes to dpu_encoder to support virtual encoder") Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/489885/ Link: https://lore.kernel.org/r/1655406084-17407-1-git-send-email-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
