Looking at the kernel source (drivers/gpu/drm/radeon/evergreen_cs.c), it appears the value:
surf.nby == 1152 is wrong. Since the layer size is 8847360 bytes and the correct height 1080 pixels, this means you have a stride of 8192 bytes per row (which is 1920 pixels rounded up to 2048, multiplied by 4 bytes per pixel). So in the least the error message looks buggy: It should not say "1920 1152". But the trigger for the error also isn't directly related to that... The trigger for the error is: /* toffset == texdw[2] << 8 == 0 */ /* depth = 1 */ /* mslice == 1 */ /* surf.layer_size == 8847360 */ if (dim == SQ_TEX_DIM_3D) { toffset += surf.layer_size * depth; } else { toffset += surf.layer_size * mslice; } /* toffset == 8847360 */ /* radeon_bo_size(texture) == 4096 */ if (toffset > radeon_bo_size(texture)) { dev_warn(p->dev, "%s:%d texture bo too small (layer size %d, " "offset %ld, max layer %d, depth %d, bo size %ld) (%d %d)\n", __func__, __LINE__, surf.layer_size, (unsigned long)texdw[2] << 8, mslice, depth, radeon_bo_size(texture), surf.nbx, surf.nby); return -EINVAL; } Those are two very different values. Of course toffset is bigger. I can't tell if that's a mistake in the kernel logic or an encoding mistake from mesa (or Xorg). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791090 Title: Xorg fails to start with radeon (kernel rejects radeon command stream from Xorg) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
