Subject: [Qemu-devel] [PATCH qemu v7 0/4] vfio-pci: Allow mmap of MSIX BAR
Date: Fri, 9 Feb 2018 18:54:59 +1100 [thread overview]
Message-ID: <20180209075503.16996-1-aik@ozlabs.ru> (raw)
Here is my latest patchset to allow mapping of MSIX BAR to the guest
in order to accelerate MMIO on certains devices.
This is based on sha1
008a51b Peter Maydell "Merge remote-tracking branch 'remotes/famz/tags/staging-pull-request' into staging".
Please comment. Thanks.
Changes:
v7:
* split into many patches
* test iova/llsize against pgmask in vfio_listener_region_add/del
* s/vfio_is_cap_present/vfio_has_region_cap/
* added comments here and there
* s/vdev->msix->table_bar/region->nr/
