Collection of DOE material, v2: * Fix WARN splat reported by Gregory Price * Migrate to synchronous API * Create DOE mailboxes in PCI core instead of in drivers * No longer require request and response size to be multiple of 4 bytes This is in preparation for CMA device authentication (PCIe r6.0, sec 6.31), which performs DOE exchanges of irregular size and is going to be handled in the PCI core. The synchronous API reduces code size for DOE users. Link to CMA development branch: https://github.com/l1k/linux/commits/doe Changes v1 -> v2: * [PATCH v2 01/10] PCI/DOE: Silence WARN splat with CONFIG_DEBUG_OBJECTS=y * Add note in kernel-doc of pci_doe_submit_task() that pci_doe_task must be allocated on the stack (Jonathan) * [PATCH v2 05/10] PCI/DOE: Make asynchronous API private * Deduplicate note in kernel-doc of struct pci_doe_task that caller need not initialize certain fields (Jonathan) Link to v1: https://lore.kernel.org/linux-pci/cover.1669608950.git.lukas@xxxxxxxxx/ Lukas Wunner (10): PCI/DOE: Silence WARN splat with CONFIG_DEBUG_OBJECTS=y PCI/DOE: Fix memory leak with CONFIG_DEBUG_OBJECTS=y PCI/DOE: Provide synchronous API and use it internally cxl/pci: Use synchronous API for DOE PCI/DOE: Make asynchronous API private PCI/DOE: Allow mailbox creation without devres management PCI/DOE: Create mailboxes on device enumeration cxl/pci: Use CDAT DOE mailbox created by PCI core PCI/DOE: Make mailbox creation API private PCI/DOE: Relax restrictions on request and response size .clang-format | 1 - drivers/cxl/core/pci.c | 89 ++++-------- drivers/cxl/cxlmem.h | 3 - drivers/cxl/pci.c | 49 ------- drivers/pci/doe.c | 315 ++++++++++++++++++++++++++++++---------- drivers/pci/pci.h | 10 ++ drivers/pci/probe.c | 1 + drivers/pci/remove.c | 2 + include/linux/pci-doe.h | 62 +------- include/linux/pci.h | 3 + 10 files changed, 283 insertions(+), 252 deletions(-) -- 2.39.1
