The firmware update support is notable as it reuses the simple sysfs_upload interface to just cat(1) a blob to a sysfs file and pipe that to the device. Additionally there are a substantial number of cleanups and reorganizations to get ready for RCH error handling (RCH == Restricted CXL Host == current shipping hardware generation / pre CXL-2.0 topologies) and type-2 (accelerator / vendor specific) devices. For vendor specific devices they implement a subset of what the generic type-3 (generic memory expander) driver expects. As a result the rework decouples optional infrastructure from the core driver context. For RCH topologies, where the specification working group did not want to confuse pre-CXL-aware operating systems, many of the standard registers are hidden which makes support standard bus features like AER (PCIe Advanced Error Reporting) difficult. The rework arranges for the driver to help the PCI-AER core. Bjorn is on board with this direction but a late regression disocvery means the completion of this functionality needs to cook a bit longer, so it is code reorganizations only for now. Summary: - Add infrastructure for supporting background commands along with support for device sanitization and firmware update - Introduce a CXL performance monitoring unit driver based on the common definition in the specification. - Land some preparatory cleanup and refactoring for the anticipated arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1 topology) error handling. - Rework CPU cache management with respect to region configuration (device hotplug or other dynamic changes to memory interleaving) - Fix region reconfiguration vs CXL decoder ordering rules" * tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (51 commits) cxl: Fix one kernel-doc comment cxl/pci: Use correct flag for sanitize polling docs: perf: Minimal introduction the the CXL PMU device and driver perf: CXL Performance Monitoring Unit driver tools/testing/cxl: add firmware update emulation to CXL memdevs tools/testing/cxl: Use named effects for the Command Effect Log tools/testing/cxl: Fix command effects for inject/clear poison cxl: add a firmware update mechanism using the sysfs firmware loader cxl/test: Add Secure Erase opcode support cxl/mem: Support Secure Erase cxl/test: Add Sanitize opcode support cxl/mem: Wire up Sanitization support cxl/mbox: Add sanitization handling machinery cxl/mem: Introduce security state sysfs file cxl/mbox: Allow for IRQ_NONE case in the isr Revert "cxl/port: Enable the HDM decoder capability for switch ports" cxl/memdev: Formalize endpoint port linkage cxl/pci: Unconditionally unmask 256B Flit errors cxl/region: Manage decoder target_type at decoder-attach time cxl/hdm: Default CXL_DEVTYPE_DEVMEM decoders to CXL_DECODER_DEVMEM ...		2023-07-01 08:58:41 -07:00
