Subject: [PATCH v2 00/24] virtio: config space endian-ness cleanup
Date: Mon, 3 Aug 2020 16:58:33 -0400 [thread overview]
Message-ID: <20200803205814.540410-1-mst@redhat.com> (raw)
Config space endian-ness is currently a mess: fields are
not tagged with the correct endian-ness so it's easy
to make mistakes like instanciating config space in
native endian-ness.
The following patches adding sparse tagging are currently in my tree.
Lightly tested.
As a follow-up, I plan to add new APIs that handle modern config space
in a more efficient way (bypassing the version check).
That is still TBD.
I also start with a version using gcc extensions, then switch
to _Generic. This is helpful for backports to older kernels/older
distros: _Generic patch can just be skipped.
Michael S. Tsirkin (24):
virtio_balloon: fix sparse warning
virtio_ring: sparse warning fixup
virtio: allow __virtioXX, __leXX in config space
virtio_9p: correct tags for config space fields
virtio_balloon: correct tags for config space fields
virtio_blk: correct tags for config space fields
virtio_console: correct tags for config space fields
virtio_crypto: correct tags for config space fields
virtio_fs: correct tags for config space fields
virtio_gpu: correct tags for config space fields
virtio_input: correct tags for config space fields
virtio_iommu: correct tags for config space fields
virtio_mem: correct tags for config space fields
virtio_net: correct tags for config space fields
virtio_pmem: correct tags for config space fields
virtio_scsi: correct tags for config space fields
virtio_config: disallow native type fields
mlxbf-tmfifo: sparse tags for config access
vdpa: make sure set_features in invoked for legacy
vhost/vdpa: switch to new helpers
virtio_vdpa: legacy features handling
vdpa_sim: fix endian-ness of config space
virtio_config: cread/write cleanup
virtio_config: rewrite using _Generic
