This primarily helps developers using the QEMU CXL emulation, but with the impending arrival of CXL switches these types of topologies will be of interest to end users. The first commit has appeared in -next for several days with no issues. The second has not aged as long, but has been verified by new unit tests. --- The following changes since commit 6d796c50f84ca79f1722bb131799e5a5710c4700: Linux 6.2-rc6 (2023-01-29 13:59:43 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl tags/cxl-fixes-6.2 for you to fetch changes up to 711442e29f16f0d39dd0e2460c9baacfccb9d5a7: cxl/region: Fix passthrough-decoder detection (2023-02-07 11:04:30 -0800) ---------------------------------------------------------------- cxl fixes for 6.2 - Fix a crash when shutting down regions in the presence of passthrough decoders - Fix region creation to understand passthrough decoders instead of the narrower definition of passthrough ports ---------------------------------------------------------------- Dan Williams (1): cxl/region: Fix passthrough-decoder detection Fan Ni (1): cxl/region: Fix null pointer dereference for resetting decoder drivers/cxl/core/region.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-)
