This series adds driver support for:
- LSI53C1030
- SAS1068
- SAS1068E
These controllers are widely supported by QEMU, VirtualBox and VMWare.
This work is part of the more general agenda of enhancing OVMF boot
device support to have feature parity with SeaBIOS.
I pushed a copy of these patches to
https://github.com/nikital/edk2/tree/mptscsi_v6
Previous versions:
https://github.com/nikital/edk2/tree/mptscsi_v5
https://github.com/nikital/edk2/tree/mptscsi_v4
https://github.com/nikital/edk2/tree/mptscsi_v3
https://github.com/nikital/edk2/tree/mptscsi (v2)
v5->v6:
- Use for "other" error ReportHostAdapterError
- Add alignment for init request
- Add PcdLib
- Use RShiftU64
- Use Pages for FreeBuffer
- Use STATIC_ASSERT for ReplyWord
- Code convention fixes
v4->v5:
- Sort maintainers and protocols
- Fix bug when restoring PCI attributes (Use Set instead of Enable)
- Separate packed structs and aligned unions
- STATIC_ASSERT for init request size
- Add support for multiple targets from the beginning
- Use PCI_BAR_IDX0 in door bell
- Code convention improvements
- Add DEBUG_VERBOSE message seen in PvScsiExitBoot
- Return EFI_INVALID_PARAMETER in GetNextTarget
- STATIC_ASSERT for MaxTarget
- Move PCD near PvScsi
- A lot of fixes for PassThru (comments, error handling, casting)
- Support 64-bit DMA
v3->v4:
- Add ExitBootServices
- Rework error handling in PassThru
- SPDX license
- Made compilation conditional
- Squash GetTargetLun and BuildDevicePath commits
- Added #include <Uefi/UefiSpec.h>
- Use PCI_BAR_IDX0
- Code convention improvements
v2->v3:
- Change error handling style
- Add comments about target size and zero unused target bytes
- Remove internal Reviewed-by
- Fix problems reported by PatchCheck.py
- Use SetupGit.py
v1->v2:
- Map() DMAed buffers
- Fixed various code convention issues
- Newer debug macros
- Updated INF version
Thanks,
Nikita

In order to probe and connect to the MptScsi device we need this
protocol. Currently it does nothing.

The MptScsiControllerSupported function is called on handles passed in
by the ConnectController() boot service and if the handle is the
lsi53c1030 controller the function would return success. A successful
return value will attach our driver to the device.

The controller supports up to 8 targets in practice (Not reported by the
controller, but based on the implementation of the virtual device),
report them in GetNextTarget and GetNextTargetLun. The firmware will
then try to communicate with them and create a block device for each one
that responds.
Support for multiple LUNs will be implemented in another series.

Enable the IO Space and Bus Mastering and restore the original values
when the device is stopped. This is a standard procedure in PCI
drivers.

Reset and send the IO controller initialization request. The reply is
read back to complete the doorbell function but it isn't useful to us
because it doesn't contain relevant data or status codes.
See "LSI53C1030 PCI-X to Dual Channel Ultra320 SCSI Multifunction
Controller" technical manual for more information.
