Suggest you hack arch/parisc/kernel/cache.c to disable this
optimization:
/* Flushing the whole cache on each cpu takes forever on
rp3440, etc. So, avoid it if the mm isn't too big. */
if (mm_total_size(mm) < parisc_cache_flush_threshold) {
It is probably the get_ptep call in the non current case that's failing
with firegl x3. It would be useful if you could test if the current case
, "mm->context == mfsp(3)" case works. You would have to move return
and disable non current block.
