| | | | | | | | | | | | | v5: - replace fixed_local_size by !LocalSizeVariable (Nicolai) v4: - slightly indent spec quotes (Nicolai) - drop useless _mesa_has_compute_shaders() check (Nicolai) - move the fixed local size outside of the loop (Nicolai) - add missing check for invalid use of work group count v2: - update formatting spec quotations (Ian) - move the total_invocations check outside of the loop (Ian) Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com>

* mesa: Don't call driver when there is no compute workJordan Justen2016-02-161-0/+3
| | | | | | | | | | The ARB_compute_shader spec says: "If the work group count in any dimension is zero, no work groups are dispatched." Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu>
* mesa: Fix format specifier warning in mesa_DispatchComputeIndirect()Rhys Kidd2015-09-301-1/+1
| | | | | | | | | | | | | | | | | | Commit 1665d29ee3125743fd6daf3c43fc715f543d5669 introduced an incorrect format specifier that operates on GLintptr indirect within the function _mesa_DispatchComputeIndirect(). This patch mitigates the introduced GCC warning: src/mesa/main/compute.c: In function '_mesa_DispatchComputeIndirect': src/mesa/main/compute.c:53:7: warning: format '%d' expects argument of type 'int', but argument 3 has type 'GLintptr' [-Wformat=] _mesa_debug(ctx, "glDispatchComputeIndirect(%d)\n", indirect); ^ v2: Amend for Boyan Ding <boyan.j.ding@gmail.com> feedback.
