That's also the maximum amount that drivers seem to be +choosing, for those drivers that do already set +`max_texture_upload_memory_budget`. + +Previously it had the default value of zero (including for Intel iris), so +`util_throttle_memory_usage` was a no-op and allowed shared memory to grow +without bounds in pathological `glTexSubImage2D` cases. + +Bug: https://gitlab.freedesktop.org/mesa/mesa/-/work_items/16408 +Bug-Ubuntu: https://bugs.launchpad.net/bugs/2143073 +Origin: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/44789 +--- + src/gallium/auxiliary/util/u_screen.c | 2 ++ + 1 file changed, 2 insertions(+) + +diff --git a/src/gallium/auxiliary/util/u_screen.c b/src/gallium/auxiliary/util/u_screen.c +index da9cdfc..6c8a698 100644 +--- a/src/gallium/auxiliary/util/u_screen.c ++++ b/src/gallium/auxiliary/util/u_screen.c +@@ -130,6 +130,8 @@ u_init_pipe_screen_caps(struct pipe_screen *pscreen, int accel) + + caps->max_varyings = 8; + ++ caps->max_texture_upload_memory_budget = 64 * 1024 * 1024; ++ + caps->throttle = true; + + #if defined(HAVE_LIBDRM) && (DETECT_OS_LINUX || DETECT_OS_BSD || DETECT_OS_MANAGARM) ===================================== debian/patches/series ===================================== @@ -1,2 +1,3 @@ path_max.diff src_glx_dri_common.h.diff +lp2143073.patch View it on GitLab: https://salsa.debian.org/xorg-team/lib/mesa/-/commit/68e4e58083d16c4785ad84aababddda126b4ecbd -- View it on GitLab: https://salsa.debian.org/xorg-team/lib/mesa/-/commit/68e4e58083d16c4785ad84aababddda126b4ecbd You're receiving this email because of your account on salsa.debian.org.
