* OvmfPkg/CpuHotplugSmm: do actual CPU hot-ejectAnkur Arora2021-03-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add logic in EjectCpu() to do the actual the CPU ejection. On the BSP, ejection happens by first selecting the CPU via its QemuSelector and then sending the QEMU "eject" command. QEMU in-turn signals the remote VCPU thread which context-switches the CPU out of the SMI handler. Meanwhile the CPU being ejected, waits around in its holding area until it is context-switched out. Note that it is possible that a slow CPU gets ejected before it reaches the wait loop. However, this would never happen before it has executed the "AllCpusInSync" loop in SmiRendezvous(). It can mean that an ejected CPU does not execute code after that point but given that the CPU state will be destroyed by QEMU, the missed cleanup is no great loss.

(It's prudent to verify whether the FUSE server supports FUSE_READDIRPLUS, so update the session init code accordingly.) This is the first FUSE request wrapper function that deals with a variable size tail buffer.

* OvmfPkg/VirtioFsDxe: implement EFI_SIMPLE_FILE_SYSTEM_PROTOCOL.OpenVolume()Laszlo Ersek2020-12-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the help of the VirtioFsFuseOpenDir() and VirtioFsFuseReleaseFileOrDir() functions introduced previously, we can now open and close the root directory. So let's implement EFI_SIMPLE_FILE_SYSTEM_PROTOCOL.OpenVolume(). OpenVolume() creates a new EFI_FILE_PROTOCOL object -- a reference to the root directory of the filesystem. Thus, we have to start tracking references to EFI_SIMPLE_FILE_SYSTEM_PROTOCOL, lest we unbind the virtio-fs device while files are open. There are two methods that release an EFI_FILE_PROTOCOL object: the Close() and the Delete() member functions. In particular, they are not allowed to fail with regard to resource management -- they must release resources unconditionally. Thus, for rolling back the resource accounting that we do in EFI_SIMPLE_FILE_SYSTEM_PROTOCOL.OpenVolume(), we have to implement the first versions of EFI_FILE_PROTOCOL.Close() and EFI_FILE_PROTOCOL.Delete() in this patch as well. With this patch applied, the UEFI shell can enter the root directory of the Virtio Filesystem (such as with the "FS3:" shell command), and the "DIR" shell command exercises FUSE_OPENDIR and FUSE_RELEASEDIR, according to the virtiofsd log. The "DIR" command reports the root directory as if it were empty; probably because at this time, we only allow the shell to open and to close the root directory, but not to read it.

| | | | | | | | | | | | | | | | | | | | | | Introduce the VIRTIO_FS_FUSE_REQUEST and VIRTIO_FS_FUSE_RESPONSE structures, which are the common headers for the various FUSE request/response structures.

* OvmfPkg/VirtioFsDxe: implement virtio device (un)initializationLaszlo Ersek2020-12-211-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the VirtioFsInit(), VirtioFsUninit(), and VirtioFsExitBoot() functions. In VirtioFsInit(): - Verify the host-side config of the virtio-fs device. - Save the filesystem label ("tag") for later, from the configuration area of the virtio-fs device. - Save the virtio queue size for later as well. - Set up the virtio ring for sending requests. In VirtioFsUninit(): - Reset the device. - Tear down the virtio ring. In VirtioFsExitBoot(): - Reset the device. With this patch, the UEFI connect / disconnect controller operations involve virtio setup / teardown; they are visible in the virtio-fs daemon's log file. The virtiofsd log also confirms the device reset in VirtioFsExitBoot(), when an OS is booted while the virtio-fs device is bound.

* OvmfPkg/VirtioFsDxe: DriverBinding: open VirtioDevice, install SimpleFsLaszlo Ersek2020-12-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complete the Supported, Start, and Stop member functions of EFI_DRIVER_BINDING_PROTOCOL sufficiently for exercising the UEFI driver model: - bind virtio-fs devices, - produce placeholder EFI_SIMPLE_FILE_SYSTEM_PROTOCOL instances on them. On the "TO_START" (= Virtio) side, the VirtioFsBindingSupported() function verifies the Virtio subsystem ID for the virtio-fs device (decimal 26 -- see <https://github.com/oasis-tcs/virtio-spec/blob/87fa6b5d8155/virtio-fs.tex>). Beyond that, no actual Virtio setup is performed for now. Those bits are going to be implemented later in this series. On the "BY_START" (= UEFI filesystem) side, the VirtioFsOpenVolume() function -- which is the sole EFI_SIMPLE_FILE_SYSTEM_PROTOCOL member function -- is a stub; it always returns EFI_NO_MEDIA, for now. The "CONNECT", "DISCONNECT", and "MAP -R" UEFI Shell commands can be used to test this patch.

| | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198 Under SEV-ES, a IOIO_PROT intercept generates a #VC exception.

* OvmfPkg/LsiScsiDxe: Process the SCSI Request PacketGary Lin2020-07-171-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the second part of LsiScsiPassThru(). LsiScsiProcessRequest() is added to translate the SCSI Request Packet into the LSI 53C895A commands. This function utilizes the so-called Script buffer to transmit a series of commands to the chip and then polls the DMA Status (DSTAT) register until the Scripts Interrupt Instruction Received (SIR) bit sets. Once the script is done, the SCSI Request Packet will be modified to reflect the result of the script. The Cumulative SCSI Byte Count (CSBC) register is fetched before and after the script to calculate the transferred bytes and update InTransferLength/OutTransferLength if necessary. v3: - Set DStat, SIst0, and SIst1 to 0 before using them - Amend the if statements for the DMA data instruction and add the assertions for the data direction - Also set SenseDataLength to 0 on the error path - Fix typos and amend comments - Amend the error handling of the calculation of transferred bytes v2: - Use the BITx macros for the most of LSI_* constants - Fix a typo: contorller => controller - Add SeaBIOS lsi-scsi driver as one of the references of the script - Cast the result of sizeof to UINT32 for the instructions of the script - Drop the backslashes - Replace LSI_SCSI_DMA_ADDR_LOW with LSI_SCSI_DMA_ADDR since we already removed DUAL_ADDRESS_CYCLE - Add more comments for the script - Fix the check of the script size at the end of the script - Always set SenseDataLength to 0 to avoid the caller to access SenseData - Improve the error handling in LsiScsiProcessRequest() Cc: Jordan Justen <jordan.l.justen@intel.com> Cc: Laszlo Ersek <lersek@redhat.com> Cc: Ard Biesheuvel <ard.biesheuvel@arm.com> Signed-off-by: Gary Lin <glin@suse.com> Message-Id: <20200717061130.8881-11-glin@suse.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com>
