Subject: [PATCH v2 00/16] hw/block/nvme: dma handling and address mapping cleanup
Date: Thu, 30 Jul 2020 00:06:22 +0200 [thread overview]
Message-ID: <20200729220638.344477-1-its@irrelevant.dk> (raw)
From: Klaus Jensen <k.jensen@samsung.com>
This series consists of patches that refactors dma read/write and adds a
number of address mapping helper functions.
v2:
* hw/block/nvme: add mapping helpers
- Add an assert in case of out of bounds array access. (Maxim)
* hw/block/nvme: remove redundant has_sg member
- Split the fix for the missing qemu_iov_destroy into a fresh patch
("hw/block/nvme: destroy request iov before reuse"). (Minwoo)
* hw/block/nvme: pass request along for tracing [DROPPED]
- Dropped the patch and replaced it with a simple patch that just adds
tracing to the nvme_map_prp function ("hw/block/nvme: add tracing to
nvme_map_prp"). (Minwoo)
* hw/block/nvme: add request mapping helper
- Changed the name from nvme_map to nvme_map_dptr. (Minwoo, Maxim)
* hw/block/nvme: add check for mdts
- Don't touch the documentaiton for the cmb_size_mb and max_ioqpairs
parameters in this patch. (Minwoo)
* hw/block/nvme: refactor NvmeRequest clearing [DROPPED]
- Keep NvmeRequest structure clearing as "before use". (Maxim)
* hw/block/nvme: add a namespace reference in NvmeRequest
* hw/block/nvme: remove NvmeCmd parameter
- Squash these two patches together into "hw/block/nvme: add ns/cmd
references in NvmeRequest".
* hw/block/nvme: consolidate qsg/iov clearing
- Move the qsg/iov destroys to a new nvme_req_exit function that is called
after the cqe has been posted.
* hw/block/nvme: remove explicit qsg/iov parameters
- New patch. THe nvme_map_prp() function doesn't require the qsg and iov
parameters since it can just get them from the passed NvmeRequest.
Based-on: <20200706061303.246057-1-its@irrelevant.dk>
