To: igt-dev; +Cc: ville.syrjala, martin.peres, stanislav.lisovskiy
Fixed run_transition_test issue, which might happen when no changes
are done and wait_transition is called and made setup_parms function
tolerate if kernel can't afford having all sprite planes enabled
depending on current mode. Remove redundant condition nesting and code.

Ok, I looked and this patch does almost exactly the same thing and has even more lines. If you think that my patch has some issue, it would be nice to at least point out what exactly, considering that I've explained what was the problem and gave appropriate reasoning regarding wm_setup_plane. Otherwise you or somebody else might just repeat the same mistake. I really see no point in this kind of review, when you say that "this is bad" and then without any explanation send almost exactly similar solution. What is wrong with wm_setup_plane having return value? Does it break anything? You doubt, this might bring problems? Just call it with 0 mask and then atomic_commit, wait_transition and you will see. Instead you just say "this is wrong", sending patch with more lines, more conditions and which needs to reviewed completely from scratch again.

Thus the test need to decrement amount of planes and try again, instead of panicking. v2: Removed excessive nested conditions, making code a bit more readable(hopefully). v3: Stopped using global n_planes variable as it might cause resources being unreleased. Using now parms[i].mask as a way to determine if plane has to be included into commit. v4: Removed unneeded n_overlays initialization. v5: Randomize which of sprite planes to remove if hitting resource limits.

There are two cases: 1) If planes to remove is less than planes left, it means that we still have some freedom for randomization which planes has to be removed. Lets say we need to remove 3, but we have for 5, then we can randomize which 3 out of 5 we can remove. So in that case we use remove variable as a random factor to decide whether plane has to be removed or not. 2) If planes to remove is equal(or more) than planes left, it means that we need to remove anyway. Lets say we need to remove 3 and we have 3. Obviously we need to remove all of those. If you still see that there is a flaw in this algorithm, can you please explain? > > > + parms[i].fb = NULL; > > + parms[i].mask = 0; > > + planes_to_remove--; > > + igt_warn("Removed plane %d\n", i); > > + } > > + else { > > + parms[i].fb = sprite_fb; > > + parms[i].mask = 1 << 2; > > + iter_mask |= 1 << 2; > > + overlays[n_overlays++] = i; > > + } > > } > > } > > > > @@ -278,16 +304,13 @@ static void setup_parms(igt_display_t > > *display, > > enum pipe pipe, > > * Pre gen9 not all sizes are supported, find the biggest > > possible > > * size that can be enabled on all sprite planes. > > */ > > -retry: > > prev_w = sprite_width = cursor_width; > > prev_h = sprite_height = cursor_height; > > > > max_sprite_width = (sprite_width == mode->hdisplay); > > max_sprite_height = (sprite_height == mode->vdisplay); > > > > - while (1) { > > - int ret; > > - > > + while (!max_sprite_width && !max_sprite_height) { > > set_sprite_wh(display, pipe, parms, sprite_fb, > > alpha, sprite_width, sprite_height); > > > > @@ -295,54 +318,49 @@ retry: > > ret = igt_display_try_commit_atomic(display, > > DRM_MODE_ATOMIC_TEST_ONLY | DRM_MODE_ATOMIC_ALLOW_MODESET, NULL); > > igt_assert(!is_atomic_check_failure_errno(ret)); > > > > - if (is_atomic_check_plane_size_errno(ret)) { > > - if (cursor_width == sprite_width && > > - cursor_height == sprite_height) { > > - igt_assert_f(alpha, > > - "Cannot configure the > > test with all sprite planes enabled\n"); > > - > > - /* retry once with XRGB format. */ > > - alpha = false; > > - goto retry; > > - } > > - > > - sprite_width = prev_w; > > - sprite_height = prev_h; > > - > > - if (max_sprite_width && max_sprite_height) { > > - set_sprite_wh(display, pipe, parms, > > sprite_fb, > > - alpha, sprite_width, > > sprite_height); > > - break; > > - } > > - > > - if (!max_sprite_width) > > - max_sprite_width = true; > > - else > > - max_sprite_height = true; > > - } else { > > + if (!is_atomic_check_plane_size_errno(ret)) { > > prev_w = sprite_width; > > prev_h = sprite_height; > > - } > > - > > - if (!max_sprite_width) { > > - sprite_width *= 2; > > - > > + > > + sprite_width *= max_sprite_width ? 1 : 2; > > if (sprite_width >= mode->hdisplay) { > > max_sprite_width = true; > > - > > sprite_width = mode->hdisplay; > > } > > - } else if (!max_sprite_height) { > > - sprite_height *= 2; > > > > + sprite_height *= max_sprite_height ? 1 : 2; > > if (sprite_height >= mode->vdisplay) { > > max_sprite_height = true; > > - > > sprite_height = mode->vdisplay; > > } > > - } else > > - /* Max sized sprites for all! */ > > - break; > > + continue; > > + } > > + > > + if (cursor_width == sprite_width && > > + cursor_height == sprite_height) { > > + igt_assert_f(retries > 0, > > + "Cannot configure the test with > > all sprite planes enabled\n"); > > + --retries; > > + /* retry once with XRGB format. */ > > + if (alpha) { > > + alpha = false; > > + igt_warn("Removed alpha\n"); > > + } > > + else { > > + igt_assert_f(n_planes > 1, "No planes > > left to proceed with!"); > > + n_planes--; > > + igt_warn("Reduced available planes to > > %d\n", n_planes); > > + } > > + goto retry; > > + } > > + > > + sprite_width = prev_w; > > + sprite_height = prev_h; > > + > > + if (!max_sprite_width) > > + max_sprite_width = true; > > + else > > + max_sprite_height = true; > > } > > > > igt_info("Running test on pipe %s with resolution %dx%d and > > sprite size %dx%d alpha %i\n", > > @@ -463,7 +481,6 @@ run_transition_test(igt_display_t *display, > > enum > > pipe pipe, igt_output_t *output > > > > if (flags & DRM_MODE_ATOMIC_ALLOW_MODESET) { > > igt_output_set_pipe(output, PIPE_NONE); > > - > > igt_display_commit2(display, COMMIT_ATOMIC); > > > > igt_output_set_pipe(output, pipe); > > @@ -525,8 +542,10 @@ run_transition_test(igt_display_t *display, > > enum > > pipe pipe, igt_output_t *output > > } > > > > /* force planes to be part of commit */ > > - for_each_plane_on_pipe(display, pipe, plane) > > - igt_plane_set_position(plane, 0, 0); > > + for_each_plane_on_pipe(display, pipe, plane) { > > + if (parms[plane->index].mask) > > + igt_plane_set_position(plane, 0, 0); > > + } > > > > igt_display_commit2(display, COMMIT_ATOMIC); > > _______________________________________________ igt-dev mailing list igt-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/igt-dev ^ permalink raw reply [flat|nested] 11+ messages in thread
