|
|
* (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))
|

* The implementation of this opcode in general consists of two parts:
|
|
* 1) determination of the memory bus width
|
|
* 2) determination of how many of the card's RAM pads have ICs attached
|
|
*
|
|
* 1) is done by a cunning combination of writes to offsets 0x1c and
|
|
* 0x3c in the framebuffer, and seeing whether the written values are
|
|
* read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
|
|
*
|
|
* 2) is done by a cunning combination of writes to an offset slightly
|
|
* less than the maximum memory reported by NV_PFB_CSTATUS, then seeing
|
|
* if the test pattern can be read back. This then affects bits 12-15 of
|
|
* NV_PFB_CFG0
|
|
*
|
|
* In this context a "cunning combination" may include multiple reads
|
|
* and writes to varying locations, often alternating the test pattern
|
|
* and 0, doubtless to make sure buffers are filled, residual charges
|
|
* on tracks are removed etc.
|
|
*
|
|
* Unfortunately, the "cunning combination"s mentioned above, and the
|
|
* changes to the bits in NV_PFB_CFG0 differ with nearly every bios
|
|
* trace I have.
|
