There is quite a long list of work to do for full spec compliance, but I don'tīelieve that any of it precludes merging. Since we've already done this work, why not use it?

To have diverging driver code in the guest programming of the HDM decoder vs. Ways to do this, but they'd require inventing a new interface and you'd need Way to tell the host how much it wants and where. Window mapping to the CXL device, the emulated HDM decoders allow the guest a After the host gives the guest a physical Mechanism for the guest to provide feedback to the host about size and This is still being fleshed out, but in short it provides a standardized Nfit_test capabilities would have made the test environment more portable,Īnd allowed for easier community contributions of example configurations.ģ. Resources via custom modules (nfit_test). The Linux kernel's unit test suite for NVDIMM/PMEM ended up injecting fake System-software developers even after hardware is available.Ģ. Of initial hardware availability, but also, as is seen with NVDIMM/PMEMĮmulation, there is value in being able to share topologies with Linux driver feature development benefits from emulation both due to a lack We have 3 reasons why this work is valuable:ġ. Persistent capacity of the memory device, I utilized the memory subsystem It seemed to be the most naturalįit even though it doesn't directly map to how hardware will work. I've chosen to use PXB (PCI Expander Bridge). Implementation utilizes existing PCI paradigms. Ports aren't implemented (the two components needed to make up a switch).ĬXL 2.0 is built on top of PCIe (see spec for details). Devices/memory devices implement the mailbo All components andĭevices implement basic MMIO. Three of the five CXL component types are emulated with some level ofįunctionality: host bridge, root port, and memory device. Its address space relative to different performance memories. There may be applications for this emulation as a way for a guest to manipulate The emulation has been critical to get the Linux enabling started, it wouldīe an ideal place to land regression tests for different topology handling, and Introduce emulation of Compute Express Link 2.0 Please feel free to use thatĬhannel for questions or suggestions in addition to #qemu. I've started #cxl on OFTC IRC for discussion.

Jonathan Cameron has gotten this patch series working on ARM, and added some The biggest change here isĭefinitely the HDM programming which has received limited (but not 0) testing in Things have remained fairly stable since since v2. * Added commands: GET_FIRMWARE_UPDATE_INFO, GET_PARTITION_INFO, GET_LSA, SET_LSA * Fixed timestamp command implementations. * Fixed HDM programming (multiple issues). * Fix component capability header generation (off by 1). This untested on big endian hosts, but Should Work(tm). * Removed all register endian/alignment/size checking.
