Subject: [PATCH 0/6] block/nvme: Map doorbells pages write-only, remove magic from nvme_init
Date: Mon, 21 Sep 2020 18:29:43 +0200 [thread overview]
Message-ID: <20200921162949.553863-1-philmd@redhat.com> (raw)
Instead of mapping 8K of I/O + doorbells as RW during the whole
execution, maps I/O temporarly at init, and map doorbells WO.
Replace various magic values by slighly more explicit macros from
"block/nvme.h".
Philippe Mathieu-Daudé (6):
util/vfio-helpers: Pass page protections to qemu_vfio_pci_map_bar()
block/nvme: Map doorbells pages write-only
block/nvme: Reduce I/O registers scope
block/nvme: Drop NVMeRegs structure, directly use NvmeBar
block/nvme: Use register definitions from 'block/nvme.h'
block/nvme: Replace magic value by SCALE_MS definition
