/*
|
||||
* SMN accesses may fail in ways that are difficult to detect here in the called
|
||||
* functions amd_smn_read() and amd_smn_write(). Therefore, callers must do
|
||||
* their own checking based on what behavior they expect.
|
||||
*
|
||||
* For SMN reads, the returned value may be zero if the register is Read-as-Zero.
|
||||
* Or it may be a "PCI Error Response", e.g. all 0xFFs. The "PCI Error Response"
|
||||
* can be checked here, and a proper error code can be returned.
|
||||
*
|
||||
* But the Read-as-Zero response cannot be verified here. A value of 0 may be
|
||||
* correct in some cases, so callers must check that this correct is for the
|
||||
* register/fields they need.
|
||||
*
|
||||
* For SMN writes, success can be determined through a "write and read back"
|
||||
* However, this is not robust when done here.
|
||||
*
|
||||
* Possible issues:
|
||||
*
|
||||
* 1) Bits that are "Write-1-to-Clear". In this case, the read value should
|
||||
* *not* match the write value.
|
||||
*
|
||||
* 2) Bits that are "Read-as-Zero"/"Writes-Ignored". This information cannot be
|
||||
* known here.
|
||||
*
|
||||
* 3) Bits that are "Reserved / Set to 1". Ditto above.
|
||||
*
|
||||
* Callers of amd_smn_write() should do the "write and read back" check
|
||||
* themselves, if needed.
|
||||
*
|
||||
* For #1, they can see if their target bits got cleared.
|
||||
*
|
||||
* For #2 and #3, they can check if their target bits got set as intended.
|
||||
*
|
||||
* This matches what is done for RDMSR/WRMSR. As long as there's no #GP, then
|
||||
* the operation is considered a success, and the caller does their own
|
||||
* checking.
