fix panfrost fault handler #24

Closed bukinr closed 2 years ago

bukinr commented 2 years ago

Fix bug in panfrost_gem_fault: the page offset is in vmf->virtual_address, not vmf->address. Rework this function so we insert the requested page to the object only, not all pages.

this makes firefox happy
