There's some "extended" GDDR3 chipsets out there with EMRS2 settings that change the layout of MRS/EMRS1 bitmaps.. Sigh.. Still need to track down how exactly we're supposed to handle this. Signed-off-by:

This will probably result in more lines of code, however, we're going to have at least 3 slightly different implementations of this very soon and I'd rather keep the ram reclocking logic separate from the hw specifics. DDR2/DDR3/GDDR3 implemented thus far, others will be added as necessary. Signed-off-by:

Statically generating the PFB register and MR values for each timing set turns out to be insufficient. There's at least one (so far) known piece of information which effects MR values which is stored in the perflvl entry on some chipsets (and in another table on later ones), which is disconnected from the timing table entries. After this change we will generate a timing set based on an input clock frequency instead, and have this data stored in the performance level data. Signed-off-by:

We might want/need the boot data to generate the other perflevels. Signed-off-by:

Roy Spliet: - Implement according to specs - Simplify - Make array for mc latency registers Martin Peres: - squash and split all the commits from Roy - rework following Ben Skeggs comments - add a form of timings validation - store the initial timings for later use Ben Skeggs - merge slightly modified tidy-up patch with this one - remove perflvl-dropping logic for the moment Signed-off-by:

It turns out we need access to some additional information in various VBIOS tables to handle PFB memory timings correctly. Rather than hack in parsing of the new stuff in some kludgy way, I've restructured the VBIOS parsing to be more primitive, so we can use them in more flexible ways in the future. The perflvl->timing association code is disabled for the moment until it can be reworked. We don't use this stuff yet anyway, so no harm done. Signed-off-by:

Module parameter descriptions don't take a trailing \n, otherwise it breaks formatting of modinfo's output. Also remove trailing space. Signed-off-by:

- Rename several VBIOS entries to closer match the real world - Add the missing 0x100238 and 0x100240 register values - Parse bit 14 of the VBIOS timing table - "Magic value" -> tCWL, fixing some minor bugs in the process - Also name a few more by their name rather than their number. - Some values seem to be dependent on the memory type. Fix Edits by Martin Peres <martin.peres@labri.fr>: - this is a squash commit - reworked for fixing some style issues Signed-off-by:

Uses only the VBIOS tables, from what I can tell this is what NVIDIA do too, I was able to change the detected memory type by modifying this table on a NVC1 chipset. Signed-off-by: -

M version 2 appears to have a table with some form of memory type info available. NVIDIA appear to ignore the table information except for this DDR2/DDR3 case (which has the same value in 0x100714). My guess is this is due to some of the supported memory types not being represented in the table. Signed-off-by: -

DDR1/DDR[23] confirmed on NVA8 (see note about DDR3 in source) by changing the value and watching the binary driver's behaviour. GDDR3/4 values confirmed on a NV96 via the same method above. That GDDR4 is present is interesting, as far as I can see no boards using it were ever released. GDDR5 value is based on VBIOS images of known GDDR5 boards. Signed-off-by: -

NV20/NV30 is partially educated guesswork at this point, based on any information around about available memory types and a horribly unspeakable amount of vbios image scouring. I'm not entirely certain the GDDR3 define is correct, I have not spotted a single vbios with that value yet (though it is mentioned in some 1218-using nv4x vbios), but there are reports that some nv3x did use it.. NV40(100914) confirmed by switching an NV49 to DDR1/DDR2 values and making sure that the binary driver behaviour showed it had detected DDR1/DDR2 instead of GDDR3 before dying horribly. NV40(100474) confirmed by doing much the same task as above on an NV44, except this was *much* easier as changing the values didn't seem to have any noticable effect on the memory controller aside from changing the binary driver's behaviour.

Most functions were quite different between NV10/NV20 already, and they're about to get even more so. Signed-off-by: -

Also, display detected memory type in logs - though, we don't even try to detect this yet. Signed-off-by:
