[PATCH 0/1] hw/arm/smmuv3: Check 31st bit to see if CD is valid

Posted by Joe Komlodi 2 years, 9 months ago

Hi all,

This fixes an off-by-1 error when checking to see if a context descriptor is
valid in SMMUv3.

I think it hasn't caused problems yet because Linux will also set the 30th bit,
which is the bit CD_VALID currently checks.

Thanks!
Joe
