[RFC 1/3] proc: Show GPU runtimes
by Chris Wilson 12 Feb '21

12 Feb '21

Present an interface for system monitors to watch the GPU usage as a whole and by individual applications. By consolidating the information into a canonical location, we have a single interface that can track the utilisation of all GPU devices and sub-devices. This is preferrable to asking the system monitors to walk the sysfs, or other interfaces, of each device and parse the custom information presented by each driver. Opens: - Should we try to name each channel so that it can be shown in UI? In gnome-system-monitor, we would have a task list: Process ... GPU0% GPU1% and charts that would show the GPU% on/next the CPU overview. Then we could have a futher expansion of a GPU% into per-channel utilisation. That would be useful to check to see what is saturating a particular channel, e.g. find the video decoder bottleneck.

[PATCH v6 0/3] Add %p4cc printk modifier for V4L2 and DRM fourcc codes
by Sakari Ailus 12 Feb '21

12 Feb '21

Hi all, This set adds support for %p4cc printk modifier for printing V4L2 and DRM fourcc codes. The codes are cumbersome to print manually and by adding the modifier, this task is saved from the V4L2 and DRM frameworks as well as related drivers. DRM actually had it handled in a way (see 3rd patch) but the printk modifier makes printing the format easier even there. On V4L2 side it saves quite a few lines of repeating different implementations of printing the 4cc codes. Further work will include converting the V4L2 drivers doing the same, as well as converting DRM drivers from drm_get_format_name() to plain %p4cc. I left these out from this version since individual drivers are easier changed without dealing with multiple trees. If DRM folks would prefer to convert drivers to %p4cc directly instead I have no problem dropping the 3rd patch. Nearly all uses in DRM are in printk family of functions that can readily use %p4cc instead of the current arrangement that relies on caller-allocated temporary buffer. Since v5: - Added V4L2 core conversion to %p4cc, as well as change the DRM fourcc printing function to use %p4cc. - Add missing checkpatch.pl checks for %p4cc modifier.

[v3] drm/msm/disp/dpu1: turn off vblank irqs aggressively in dpu
by Kalyan Thota 12 Feb '21

12 Feb '21

From: Kalyan Thota <kalyant(a)codeaurora.org> Set the flag vblank_disable_immediate = true to turn off vblank irqs immediately as soon as drm_vblank_put is requested so that there are no irqs triggered during idle state. This will reduce cpu wakeups and help in power saving. To enable vblank_disable_immediate flag the underlying KMS driver needs to support high precision vblank timestamping and also a reliable way of providing vblank counter which is incrementing at the leading edge of vblank. This patch also brings in changes to support vblank_disable_immediate requirement in dpu driver. Changes in v1: - Specify reason to add vblank timestamp support. (Rob Clark) - Add changes to provide vblank counter from dpu driver. Changes in v2: - Fix warn stack reported by Rob Clark with v2 patch Signed-off-by: Kalyan Thota <kalyan_t(a)codeaurora.org> --- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 80 +++++++++++++++++++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 28 +++++++++- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.h | 11 ++++ drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 5 ++ 4 files changed, 123 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c index d4662e8..9a80981 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c @@ -65,6 +65,83 @@ static void dpu_crtc_destroy(struct drm_crtc *crtc) kfree(dpu_crtc); } +static struct drm_encoder *get_encoder_from_crtc(struct drm_crtc *crtc) +{ + struct drm_device *dev = crtc->dev; + struct drm_encoder *encoder; + + drm_for_each_encoder(encoder, dev) + if (encoder->crtc == crtc) + return encoder; + + return NULL; +} + +static u32 dpu_crtc_get_vblank_counter(struct drm_crtc *crtc) +{ + struct drm_encoder *encoder; + + encoder = get_encoder_from_crtc(crtc); + if (!encoder) { + DRM_ERROR("no encoder found for crtc %d\n", crtc->index); + return false; + } + + return dpu_encoder_get_frame_count(encoder); +} + +static bool dpu_crtc_get_scanout_position(struct drm_crtc *crtc, + bool in_vblank_irq, + int *vpos, int *hpos, + ktime_t *stime, ktime_t *etime, + const struct drm_display_mode *mode) +{ + unsigned int pipe = crtc->index; + struct drm_encoder *encoder; + int line, vsw, vbp, vactive_start, vactive_end, vfp_end; + + encoder = get_encoder_from_crtc(crtc); + if (!encoder) { + DRM_ERROR("no encoder found for crtc %d\n", pipe); + return false; + } + + vsw = mode->crtc_vsync_end - mode->crtc_vsync_start; + vbp = mode->crtc_vtotal - mode->crtc_vsync_end; + + /* + * the line counter is 1 at the start of the VSYNC pulse and VTOTAL at + * the end of VFP.

[PATCH] drm/msm/dp: Add a missing semi-colon
by Stephen Boyd 12 Feb '21

12 Feb '21

A missing semicolon here causes my external display to stop working. Indeed, missing the semicolon on the return statement leads to dp_panel_update_tu_timings() not existing because the compiler thinks it's part of the return statement of a void function, so it must not be important. $ ./scripts/bloat-o-meter before.o after.o add/remove: 1/1 grow/shrink: 0/1 up/down: 7400/-7540 (-140) Function old new delta dp_panel_update_tu_timings - 7400 +7400 _dp_ctrl_calc_tu.constprop 18024 17900 -124 dp_panel_update_tu_timings.constprop 7416 - -7416 Total: Before=54440, After=54300, chg -0.26% Add a semicolon so this function works like it used to.

Not 100% sure if I correctly fixed drm-tip
by Christian König 12 Feb '21

12 Feb '21

Hi guys, I had a conflict this morning in the ttm pool while pushing an important fix to drm-misc-fixes. I'm not 100% sure if I correctly fixed up drm-tip. How can this be double checked? And how can it be fixed if the merge has gone bad? Thanks, Christian.
