[Qemu-devel] [PATCH v3 0/8] msix: Support specifying offsets, BARs, and capability location |

StGIT/0.14.3 |
v3:
- more patches, smaller diff, must be headed in the right direction
- macros for all hardcoded values in msix_init_exclusive_bar
- fold msix_add_config into msix_init allowing less churn to moving
around msix_uninit
- note native endian bug
- split msix_mmio_read move to separate patch
- split changing return value of msix_uninit to separate patch
Thanks,
Alex
v2:
- split patch
- rename msix_[un]init_bar() to msix_[un]init_exclusive_bar()
- add the cherry on top to cleaning up PCIDevice naming
v1:
msix_init has very little configurability as to how it lays out MSIX
for a device. It claims to resize BARs, but doesn't actually do this
anymore. This patch allows MSIX to be fully specified, which is
necessary both for emulated devices trying to match the physical
layout of a hardware device as well as for any kind of device
assignment.
New functions msix_init_bar & msix_uninit_bar provide wrappers around
the more detailed functions for drivers that just want a simple MSIX
setup.

Alex Williamson (8):
msix: Switch msix_uninit to return void
msix: Allow full specification of MSIX layout
msix: Split PBA into it's own MemoryRegion
msix: Note endian TODO item
msix: Move msix_mmio_read
virtio: Convert to msix_init_exclusive_bar() interface
ivshmem: Convert to msix_init_exclusive_bar() interface
msix: Add simple BAR allocation MSIX setup functions
