* offset (8 bit): opcode
*
- * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so
- * that the hardware can correctly calculate how much VRAM it has
- * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))
+ * This opcode is meant to set the PFB memory config registers
+ * appropriately so that we can correctly calculate how much VRAM it
+ * has (on nv10 and better chipsets the amount of installed VRAM is
+ * subsequently reported 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
+ * The implementation of this opcode in general consists of several
+ * parts:
*
- * 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
+ * 1) Determination of memory type and density. Only necessary for
+ * really old chipsets, the memory type reported by the strap bits
+ * (0x101000) is assumed to be accurate on nv05 and newer.
*
- * 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
+ * 2) Determination of the memory bus width. Usually done by a cunning
+ * combination of writes to offsets 0x1c and 0x3c in the fb, and
+ * seeing whether the written values are read back correctly.
*
- * 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.
+ * Only necessary on nv0x-nv1x and nv34, on the other cards we can
+ * trust the straps.
*
- * 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.
+ * 3) Determination of how many of the card's RAM pads have ICs
+ * attached, usually 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.
*
- * Therefore, we cheat and assume the value of NV_PFB_CFG0 with which
- * we started was correct, and use that instead
+ * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
+ * logs of the VBIOS and kmmio traces of the binary driver POSTing the
+ * card show nothing being done for this opcode. Why is it still listed
