-Subject: [PATCH 128/139] drivers/pc80: Add optional spinlock for nvram CBFS
- access
-
-When enabling the IOMMU on certain systems dmesg is spammed with I/O page faults like the following:
-AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030]
-
-Decoding the faulting address:
-0x000000fdf9103300
-        fdf91x          Hypertransport system management region
-              33        SysMgtCmd (System Management Command) = 0x33
-              3         Base Command Type = 0x3: STPCLK (Stop Clock request)
-               3        SMAF (System Management Action Field) = [3:1] = 0x1
-               1        Signal State Bit Map = [0] = 0x1
-
-Therefore, the error appears to be triggered by an upstream C1E request.
-
-This was eventually traced to concurrent access to the SP5100's SMBus controller by
-multiple APs during startup.  Calls to the nvram read functions get_option and read_option
-call CBFS functions, which in turn make near-simultaneous requests to the SMBus controller,
-thus placing the SP5100 in an invalid state.  This limitation is not documented in any public
-AMD errata, and was only discovered through considerable debugging effort.
