https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=223572 Bug ID: 223572 Summary: drm(4) pmap_mapdev()s PCI space addresses Product: Base System Version: CURRENT Hardware: powerpc OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: jhibbits@FreeBSD.org drm_get_resource_start() gets an rman resource start, which is not always physical address. On PowerPC, and any architecture that uses OFW/FDT, the resources are specified in PCI space, not physical address space. This causes the wrong mappings to be generated, potentially stomping on real memory. -- You are receiving this mail because: You are the assignee for the bug.help
