The new class defines UNPACKDIR for scarthgap but leaves it undefined for wrynose and later as they require. (It is defined as a weak assignment that will be active later in the processing.) This is a separate commit so it can be reverted for release specific branches and when scrathgap goes EOL.

The original commit was introduced to support repeat attach-detach. Since Linux side need to fix remoteproc virtio reset mechanism, this commit becomes irrelevant. Also, this commit creates problems during multiple reboot of the remote processor. Hence revert it until remoteproc virtio reset mechanism is fixed in the linux kernel, and then this commit will be re-introduced as needed.

Unique Device Status value to indicate reset request

by Bill Mills

TLDR: virtio-remoteproc device reset To request a device reset (w/ acknowledgement), the driver should val = Status field // read current status field val |= 0x82 // set bits 7 and 1 (FAILED and DRIVER) val &= 0xfe // clear bit 0 (ACKNOWLEDGE) // leave other bits unchanged Status field = val // write the new status field value The driver should then poll the status field waiting for it to be == 0. Note: writing the status field to 0 when it is already non-zero, should continue to work as a device reset but the driver will not know when it is complete. Background: From the virtio spec [1] with extra clarity added by me. Status Field bits: (Spec section 2.1, html [2]) bit 0, 0x01, dec 1 ACKNOWLEDGE bit 1, 0x02, dec 2 DRIVER bit 2, 0x04, dec 4 DRIVER_OK (also used in suspend protocol) bit 3, 0x08, dec 8 FEATURES_OK bit 4, 0x10, dec 16 SUSPEND only used if negotiated bit 5, 0x20, dec 32 (currently unused) bit 6, 0x40, dec 64 DEVICE_NEEDS_RESET bit 7, 0x80, dec 128 FAILED All bits except DEVICE_NEEDS_RESET are set (and sometimes cleared) by the device. DEVICE_NEEDS_RESET is set by the device and should only be cleared by a reset. Logically the driver sets ACKNOWLEDGE, then DRIVER, then DRIVER_OK, then FEATURES_OK. Some of these could be set at the same time but never higher bits before lower bits. Once these bits are set, the driver in not allowed to clear them except by issuing a device reset. The one exception to this is that the DRIVER_OK bit is cleared and set as part of the SUSPEND protocol but only if it has been negotiated. The driver sets the FAILED bit when it has given up on the device. It is valid for FAILED with any of the following settings: 0b1xxx_0000 Fail before ack 0b1xxx_0001 Fail before driver found 0b1xxx_0011 Fail before driver OK 0b1xxx_0111 Fail before features OK 0b1xxx_1111 Fail after features OK And if SUSPEND has been negotiated 0b1xx1_0011 Fail while suspend active before features OK 0b1xx1_1011 Fail while Suspend active after features OK FAILED(0x80) and DRIVER (0x02) active with ACKNOWLEDGE(0x01) cleared is not a value that is possible in the base spec. Therefore we use this setting to request a reset w/ acknowledgement. 0b1xxx_xx10 Reset Request w/ acknowledgement TBD: Does/Should the driver send a notification on Status field change? Does/Should the device send a notification on Status field change? Sending the notice eliminates the need for a time on the other side to poll. Do we already support this? If not, probibly not worth it just for this protocol. Recent virtio-mmio enhancement: The patch in [3] is now in the virtio spec master branch but is not part of any released version yet. The patch adds a new V3 version of virtio-mmio where the driver can issue a non-blocking reset request and poll the status field to know when it is done. So we are not the only ones to notice this issue. However the solution used for virtio-mmio still requires trap and emulate to work and wont work if the Status field in located in normal memory of any type. In the patch the driver still writes 0 to the status field but the device is allowed to return from the MMR write with the status filed non-zero. The driver then waits for the status field to become zero to know when this operation is complete. This solution will not work for us as we use a real memory to store the status field and the driver writing that to 0 will take immediate effect and the driver then polling for zero would succeed immediately.
