[PATCH v2 00/10] hw/virtio: Build various target-agnostic objects just once

[PATCH v2 00/10] hw/virtio: Build various target-agnostic objects just once

[Philippe Mathieu-Daudé]

All patches reviewed.

Since v1:
- Addressed Richard & Thomas review comments
  . qemu_target_page_align() dropped
  . qemu_target_page_mask() returns signed
  . meson shuffle
- Collected R-b/T-b/A-b tags
- Dropped vhost-vdpa patch (to be posted as another series)

Less controvertial than my first approach [*] which caches
the access_is_big_endian value in VirtIODevice state, this
series just remove a unnecessary / pointless dependency on
"virtio-access.h", allowing to build various virtio objects
once for all targets.

[PATCH v2 01/10] softmmu: Introduce qemu_target_page_mask() helper

[Philippe Mathieu-Daudé]

Since TARGET_PAGE_MASK is poisoned in target-agnostic code,
introduce the qemu_target_page_mask() helper to get this
value from target-agnostic code at runtime.

Instead of adding 'vhost-scsi-common.c' twice (for VHOST_SCSI and

[PATCH v2 04/10] hw/scsi: Rename target-specific source set as 'specific_virtio_scsi_ss'

[Philippe Mathieu-Daudé]

Following the SCSI variable named '[specific_]scsi_ss', rename the
target-specific VirtIO/SCSI set prefixed with 'specific_'. This will
help when adding target-agnostic VirtIO/SCSI set in few commits.

[PATCH v2 08/10] hw/virtio/virtio-iommu: Use target-agnostic qemu_target_page_mask()

[Philippe Mathieu-Daudé]

In order to have virtio-iommu.c become target-agnostic,
we need to avoid using TARGET_PAGE_MASK. Get it with the
qemu_target_page_mask() helper.

[PATCH v2 09/10] hw/virtio: Remove unnecessary 'virtio-access.h' header

[Philippe Mathieu-Daudé]

None of these files use the VirtIO Load/Store API declared
by "hw/virtio/virtio-access.h". This header probably crept
in via copy/pasting, remove it.

Note, "virtio-access.h" is target-specific, so any file
including it also become tainted as target-specific.

[PATCH v2 10/10] hw/virtio: Build various target-agnostic objects just once

[Philippe Mathieu-Daudé]

The previous commit remove the unnecessary "virtio-access.h"
header. These files no longer have target-specific dependency.
Move them to the generic 'softmmu_ss' source set.
