Clients will not be notified of the SYSERR via the destruction +of their channel devices, which means clients may think that the device is +still up. Subsequent SYSERR events such as a device fatal error will not +be processed as the state machine cannot transition from PROCESS back to +DETECT. The only way to recover from this is to unload the mhi module +(wipe the state machine state) or for the mhi controller to initiate +SHUTDOWN. + +This issue was discovered by stress testing soc_reset events on AIC100 +via the sysfs node. + +soc_reset is processed entirely in hardware. When the register write +hits the endpoint hardware, it causes the soc to reset without firmware +involvement. In stress testing, there is a rare race where soc_reset N +will cause the soc to reset and PBL to signal SYSERR (fatal error). If +soc_reset N+1 is triggered before PBL can process the MHI_RESET from the +host, then the soc will reset again, and re-run PBL from the beginning. +This will cause PBL to lose all state. PBL will be waiting for the host +to respond to the new syserr, but host will be stuck expecting the +previous MHI_RESET to be processed. + +Additionally, the AMSS EE firmware (QSM) was hacked to synthetically +reproduce the issue by simulating a FW hang after the QSM issued a +SYSERR. In this case, soc_reset would not recover the device. + +For this failure case, to recover the device, we need a state similar to +PROCESS, but can transition to DETECT. There is not a viable existing +state to use. POR has the needed transitions, but assumes the device is +in a good state and could allow the host to attempt to use the device. +Allowing PROCESS to transition to DETECT invites the possibility of +parallel SYSERR processing which could get the host and device out of +sync. + +Thus, invent a new state - MHI_PM_SYS_ERR_FAIL + +This essentially a holding state. It allows us to clean up the host +elements that are based on the old state of the device (channels), but +does not allow us to directly advance back to an operational state. It +does allow the detection and processing of another SYSERR which may +recover the device, or allows the controller to do a clean shutdown. + +Signed-off-by: Jeffrey Hugo +Reviewed-by: Carl Vanderlip +Reviewed-by: Manivannan Sadhasivam +Link: https://lore.kernel.org/r/20240112180800.536733-1-quic_jhugo@quicinc.com +Signed-off-by: Manivannan Sadhasivam +Signed-off-by: Sasha Levin +--- + drivers/bus/mhi/host/init.c | 1 + + drivers/bus/mhi/host/internal.h | 9 ++++++--- + drivers/bus/mhi/host/pm.c | 20 +++++++++++++++++--- + 3 files changed, 24 insertions(+), 6 deletions(-) + +diff --git a/drivers/bus/mhi/host/init.c b/drivers/bus/mhi/host/init.c +index f78aefd2d7a36..cfd17c02fe20e 100644 +--- a/drivers/bus/mhi/host/init.c ++++ b/drivers/bus/mhi/host/init.c +@@ -62,6 +62,7 @@ static const char * const mhi_pm_state_str[] = { + [MHI_PM_STATE_FW_DL_ERR] = "Firmware Download Error", + [MHI_PM_STATE_SYS_ERR_DETECT] = "SYS ERROR Detect", + [MHI_PM_STATE_SYS_ERR_PROCESS] = "SYS ERROR Process", ++ [MHI_PM_STATE_SYS_ERR_FAIL] = "SYS ERROR Failure", + [MHI_PM_STATE_SHUTDOWN_PROCESS] = "SHUTDOWN Process", + [MHI_PM_STATE_LD_ERR_FATAL_DETECT] = "Linkdown or Error Fatal Detect", + };

The VF driver reports this value +back to the PF in a variety of commands. The PF driver validates that this +value matches the value it sent to the VF. + +Some hardware families such as the E700 series could use this value when +reading RSS registers or communicating directly with firmware over the +Admin Queue. + +However, E800 series hardware does not support any of these interfaces and +the VF's only use for this value is to report it back to the PF. Thus, +there is no requirement that this value be an actual VSI ID value of any +kind. + +The PF driver already does not trust that the VF sends it a real VSI ID. +The VSI structure is always looked up from the VF structure. The PF does +validate that the VSI ID provided matches a VSI associated with the VF, but +otherwise does not use the VSI ID for any purpose. + +Instead of reporting the VSI number relative to the PF space, report a +fixed value of 1. When communicating with the VF over virtchnl, validate +that the VSI number is returned appropriately. + +This avoids leaking information about the firmware of the PF state. +Currently the ice driver only supplies a VF with a single VSI. However, it +appears that virtchnl has some support for allowing multiple VSIs. I did +not attempt to implement this. However, space is left open to allow further +relative indexes if additional VSIs are provided in future feature +development. For this reason, keep the ice_vc_isvalid_vsi_id function in +place to allow extending it for multiple VSIs in the future. + +This change will also simplify handling of live migration in a future +series.
