[SeaBIOS] [PATCHv2 0/6] Rework NVME page transfers and avoid fsegment allocation
Posted by Kevin O'Connor 8 months, 1 week ago
This is a resend of the previous series.  Changes since last time:

* Patch 1: Fix function comment on nvme_io_xfer()
* Patch 3-5: Added "goto bounce" to nvme_io_xfer() as suggested by Alex
* Patch 6: Added separate "single dma bounce buffer" patch to this series
* Patch 6: Add checking for malloc failure

-Kevin


Kevin O'Connor (6):
  nvme: Rework nvme_io_readwrite() to return -1 on error
  nvme: Add nvme_bounce_xfer() helper function
  nvme: Convert nvme_build_prpl() to nvme_prpl_xfer()
  nvme: Pass prp1 and prp2 directly to nvme_io_xfer()
  nvme: Build the page list in the existing dma buffer
  nvme: Only allocate one dma bounce buffer for all nvme drives

Thanks a lot for cleaning up that code! I agree that it's a lot more 
readable after your patches :)
