Hi - I've got a question about what optimizations the "inbounds" keyword of "getelementptr" allows you to use. In the code below, %five is loaded from and inbounds offset of either a null pointer or %mem: target datalayout = "e-i64:64-f80:128-n8:16:32:64-S128" define i8 @func(i8* %mem) { %test = icmp eq i8* %mem, null br i1 %test, label %done, label %mem.is.valid mem.is.valid: %1 = getelementptr inbounds i8, i8* %mem, i64 4 store i8 5, i8* %1, align 4 br label %done done: %a...

GK20A's RAM driver was using CMA functions in order to allocate VRAM. This is wrong because these functions are not exported, which causes compilation to fail when CMA is enabled and Nouveau is built as a module. On top of that the driver was leaking (or rather bleeding) memory. dma_alloc_coherent() will also use CMA when needed but has the advantage of being properly exported. It creates a permanent kernel mapping, but experiment revealed that the lowmem mapping is actually reused, and this mapping can also be taken advantage of to implement faster instmem. We lose t...

Hi, I want some config depending on memorysize. What I tried was if ($memorysize >= 256 * 1024*1024) { ... } But this fails because $memorysize is a string (and contains a "G") and can''t be compared to an int. Are all facts strings? How do I work with numbers? regards, Andreas -- Andreas Kuntzagk System...

Just a gentle ping on this. Already got the Acked-by from Daniel, but I need some of the nouveau guys to test this since I can only compile test it. Regards, Christian.

Hi guys, so I got some hardware and tested this and after hammering out tons of typos it now seems to work fine. Could you give it more testing? Thanks in advance, Christian

Hi guys, I've already send this out in September last year, but only got a response from Daniel. Could you guys please test this and tell me what you think about it? Basically I'm trying to remove all driver specific features from TTM which don't need to be inside the framework. Thanks, Christian.

While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. The patch should be functional correct, but is only compile tested!

This patch causes "xm mem-set" to be lower bound on domX-min-mem option in xend-config. Another configuration option called domU-min-mem has been introduced, which works similarly to dom0-min-mem. This is prevents users from freezing the system when doing "xm mem-set" on very low values like 32M. Signed-off-...
