Subject: [PATCH v2 00/10] Collection of DOE material
Date: Mon, 23 Jan 2023 11:10:00 +0100	[thread overview]
Message-ID: <cover.1674468099.git.lukas@wunner.de> (raw)

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.

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)
