A late bug was reported by Robert Richter that the Restricted CXL Host (RCH) support was missing in the CXL endpoint access_coordinate calculation. The missing support causes the topology iterator to stumble over a NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1 support. The fix bypasses RCH topology as the access_coordinate calculation is not necessary since RCH does not support hotplug and the memory region exported should be covered by the HMAT table already. A unit test is also added to cxl_test to check against future regressions on the topology iterator" * tag 'cxl-fixes-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl: Fix cxl_endpoint_get_perf_coordinate() support for RCH |
