From: Gert Wollny <gert.wol...@collabora.com> For testing it is of interetest that all tests of dEQP pass, e.g. to test virglrenderer on a host only providing software rendering like in a CI. Hence make it possible to disable certain optimizations that make tests fail.
While we are there also add some documentation to the flags to make it clear that this is opt-out. Setting the environment variable "GALLIVM_PERF=disable_all" can be used to make the follwing tests pass in release mode: dEQP-GLES2.functional.texture.mipmap.2d.affine.*_linear_* dEQP-GLES2.functional.texture.mipmap.cube.generate.* dEQP-GLES2.functional.texture.vertex.2d.filtering.*_mipmap_linear_* dEQP-GLES2.functional.texture.vertex.2d.wrap.* Related: https://bugs.freedesktop.org/show_bug.cgi?id=94957 Signed-off-by: Gert Wollny <gert.wol...@collabora.com> --- src/gallium/auxiliary/gallivm/lp_bld_debug.h | 13 ++++++++----- src/gallium/auxiliary/gallivm/lp_bld_init.c | 15 ++++++++++++--- src/gallium/auxiliary/gallivm/lp_bld_sample_soa.c | 6 +++--- src/gallium/auxiliary/gallivm/lp_bld_tgsi_soa.c | 6 +++--- 4 files changed, 26 insertions(+), 14 deletions(-) diff --git a/src/gallium/auxiliary/gallivm/lp_bld_debug.h b/src/gallium/auxiliary/gallivm/lp_bld_debug.h index f96a1afa7a..ce09d789cb 100644 --- a/src/gallium/auxiliary/gallivm/lp_bld_debug.h +++ b/src/gallium/auxiliary/gallivm/lp_bld_debug.h @@ -41,18 +41,21 @@ #define GALLIVM_DEBUG_ASM (1 << 2) #define GALLIVM_DEBUG_NO_OPT (1 << 3) #define GALLIVM_DEBUG_PERF (1 << 4) -#define GALLIVM_DEBUG_NO_BRILINEAR (1 << 5) -#define GALLIVM_DEBUG_NO_RHO_APPROX (1 << 6) -#define GALLIVM_DEBUG_NO_QUAD_LOD (1 << 7) -#define GALLIVM_DEBUG_GC (1 << 8) -#define GALLIVM_DEBUG_DUMP_BC (1 << 9) +#define GALLIVM_DEBUG_GC (1 << 5) +#define GALLIVM_DEBUG_DUMP_BC (1 << 6) +#define GALLIVM_PERF_NO_BRILINEAR (1 << 0) +#define GALLIVM_PERF_NO_RHO_APPROX (1 << 1) +#define GALLIVM_PERF_NO_QUAD_LOD (1 << 2) + #ifdef __cplusplus extern "C" { #endif +extern unsigned gallivm_perf;
