Request: Smart Access Memory information

GC = Graphics Core (I prefer GFX over GC though)....

Different gcc versions print different warnings. Other gcc versions have buggy warnings. Good luck building the kernel everywhere.

~1 month to get everything reviewed, probably less....

The current gap for Snx between pro drivers and Mesa is ~2% with my private branch....

because it's fun...

I'll take that as a joke. ...

[marek]

Nobody said it was an issue....

[marek]

Only special cases, usually old BIOSes, old CPUs, or old GPUs. You should be fine with Ryzen 5000 and Radeon RX 6000, which is the only configuration...

The performance can decrease with Above 4G Decoding due to unknown reasons because this is all experimental and might not have been validated by hardware...

One of the advantages of SAM is that it makes SDMA obsolete because the CPU can write to VRAM directly. I think this is the biggest performance uplift...

If vram_vis_size is the same as vram_size, you have Smart Access Memory enabled. You both have it.

I have Ryzen 3900X but the chipset is...

Hi,

Can you run this command and post the output if vram_vis_size is greater than 256 MB? It means that Smart Access Memory is enabled. I'd...

There is no stall. The only difference is better CU utilization due to lower register usage thanks to removed never-taken conditional branches....

Note that we (AMD) have never said what gfx10.3 is. In theory, it might not be related to any of our upcoming products.

If the performance is 0, then 50-100% faster is still 0.
