2025-03-14cxl/pmem: debug invalid serial number dataYuquan Wang
In a nvdimm interleave-set each device with an invalid or zero serial number may cause pmem region initialization to fail, but in cxl case such device could still set cookies of nd_interleave_set and create a nvdimm pmem region. This adds the validation of serial number in cxl pmem region creation. The event of no serial number would cause to fail to set the cookie and pmem region. For cxl-test to work properly, always +1 on mock device's serial number.

2025-03-14acpi/ghes, cxl/pci: Process CXL CPER Protocol ErrorsSmita Koralahalli
When PCIe AER is in FW-First, OS should process CXL Protocol errors from CPER records. Introduce support for handling and logging CXL Protocol errors. The defined trace events cxl_aer_uncorrectable_error and cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them to trace FW-First Protocol errors. Since the CXL code is required to be called from process context and GHES is in interrupt context, use workqueues for processing. Similar to CXL CPER event handling, use kfifo to handle errors as it simplifies queue processing by providing lock free fifo operations. Add the ability for the CXL sub-system to register a workqueue to process CXL CPER protocol errors.

2025-03-14selftests: drv-net: fix merge conflicts resolutionMatthieu Baerts (NGI0)
After the recent merge between net-next and net, I got some conflicts on my side because the merge resolution was different from Stephen's one [1] I applied on my side in the MPTCP tree. It looks like the code that is now in net-next is using the old way to retrieve the local and remote addresses. This patch is now using the new way, like what was in Stephen's email [1]. Also, in get_interface_info(), there were no conflicts in this area, because that was new code from 'net', but a small adaptation was needed there as well to get the remote address.

So, it adds XDP environment, existing tests(test_v4, test_v6, and test_tcp) are executed too on the below XDP environment. So, it adds XDP cases. 1. xdp-generic + single-buffer 2. xdp-generic + multi-buffer 3. xdp-native + single-buffer 4. xdp-native + multi-buffer 5. xdp-offload It also makes test_{v4 | v6 | tcp} sending large size packets. this may help to check whether multi-buffer is working or not. Note that the physical interface may be down and then up when xdp is attached or detached. This takes some period to activate traffic. So sleep(10) is added if the test interface is the physical interface. netdevsim and veth type interfaces skip sleep.

2025-03-10selftests: ublk: make ublk_stop_io_daemon() more reliableMing Lei
Improve ublk_stop_io_daemon() in the following ways: - don't wait if ->ublksrv_pid becomes -1, which means that the disk has been stopped - don't wait if ublk char device doesn't exist any more, so we can avoid to rely on inoitfy for wait until the char device is closed And this way may reduce time of delete command a lot.

2025-03-08selftests: pci_endpoint: Skip disabled BARsNiklas Cassel
Currently BARs that have been disabled by the endpoint controller driver will result in a test FAIL. Returning FAIL for a BAR that is disabled seems overly pessimistic. There are EPC that disables one or more BARs intentionally. One reason for this is that there are certain EPCs that are hardwired to expose internal PCIe controller registers over a certain BAR, so the EPC driver disables such a BAR, such that the host will not overwrite random registers during testing. Such a BAR will be disabled by the EPC driver's init function, and the BAR will be marked as BAR_RESERVED, such that it will be unavailable to endpoint function drivers. Let's return FAIL only for BARs that are actually enabled and failed the test, and let's return skip for BARs that are not even enabled.

The execution order of constructors in undefined and depends on the toolchain. While recent toolchains seems to have a stable order, it doesn't work for older ones and may also change at any time.
