Title:
openCL application gives error after update
Status in libclc package in Ubuntu:
Triaged
Status in libclc source package in Bionic:
New
Status in libclc source package in Eoan:
New
Bug description:
My OpenCL program was working normally until a software update.
The program prints out:
ac_rtld error: !s->is_rx
LLVM failed to upload shader
when clEnqueueNDRangeKernel is called.
I've downloaded the source for mesa and traced the problem to the
gallium radeon driver. The first error message is from
mesa-19.2.1/src/amd/common/ac_rtld.c
and the second error message is from
mesa-19.2.1/src/gallium/drivers/radeonsi/si_compute.c
