|
* Notes on internal configuration of ESCR+CCCR tuples
|
|
*
|
|
* Since P4 has quite the different architecture of
|
|
* performance registers in compare with "architectural"
|
|
* once and we have on 64 bits to keep configuration
|
|
* of performance event, the following trick is used.
|
|
*
|
|
* 1) Since both ESCR and CCCR registers have only low
|
|
* 32 bits valuable, we pack them into a single 64 bit
|
|
* configuration. Low 32 bits of such config correspond
|
|
* to low 32 bits of CCCR register and high 32 bits
|
|
* correspond to low 32 bits of ESCR register.
|
|
*
|
|
* 2) The meaning of every bit of such config field can
|
|
* be found in Intel SDM but it should be noted that
|
|
* we "borrow" some reserved bits for own usage and
|
|
* clean them or set to a proper value when we do
|
|
* a real write to hardware registers.
|
|
*
|
|
* 3) The format of bits of config is the following
|
|
* and should be either 0 or set to some predefined
|
|
* values:
|
|
*
|
|
* Low 32 bits
