similar to: [PATCH 1/4] drm: remove optional dummy function from drivers using TTM

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.

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! Signed-off-by: Christian König <christian.koenig at

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.

We are trying to remove the io_lru handling and depend on zero init base, offset and addr here. v2: init addr as well Signed-off-by: Christian K?nig <christian.koenig at amd.com> --- drivers/gpu/drm/ttm/ttm_bo.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/drivers/gpu/drm/ttm/ttm_bo.c b/drivers/gpu/drm/ttm/ttm_bo.c index e3931e515906..772c640a6046 100644 ---

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

Without diving in any of the details, your commit message has me curious and concerned... In a "manager" kind of way, despite being neither a manager nor an insider or active contributor. ;-) On 24/01/2020 14:30, Christian K?nig wrote: > From: Christian K?nig <ckoenig.leichtzumerken at gmail.com> > > While working on TTM cleanups I've found that the io_reserve_lru

The ttm_mem_io_* functions are actually internal to TTM and shouldn't be used in a driver. Instead call the qxl_ttm_io_mem_reserve() function directly.

Several simple framebuffer drivers copy most of the TTM code from each other. The implementation is always the same; except for the name of some data structures. As recently discussed, this patch set provides generic memory-management code for simple framebuffers with dedicated video memory. It further converts the respective drivers to the generic code. The shared code is basically the same

Hi guys, while working through more old TTM functionality I stumbled over the io_reserve_lru. Basic idea is that when this flag is set the driver->io_mem_reserve() callback can return -EAGAIN resulting in unmapping of other BOs. But Nouveau doesn't seem to return -EAGAIN in the call path of io_mem_reserve anywhere. So is this unused or am I missing something? Regards, Christian.

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Thomas Zimmermann (4): drm/vram: Move VRAM memory manager to GEM VRAM implementation drm/vram: Have VRAM MM call GEM VRAM functions directly drm/vram: Unexport internal functions of VRAM MM drm/vram: Unconditonally set BO call-back

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Version 2 of the patch set doesn't contain functional changes. I'm reposting due to the rebasing onto the debugfs patches. v2: * updated for debugfs support * fixed typos in comments Thomas Zimmermann (4): drm/vram: Move VRAM

Hi guys, I already tried this a few month ago, but since I don't have NVidia hardware its rather hard to test for me (need to get some ordered). Dave brought up the topic that we should probably try to move the handling into Nouveau once more, so I tried to fix the problem Ben reported and rebased on top of current drm-misc-next. Dave can you test this? At least in theory the approach

I have no idea what this bogus restriction on placement is, but it breaks decoding 1080p VDPAU at boot speed. With this patch applied I only need to bump the vdec clock to get real-time 1080p decoding. It prevents a lot of VRAM <-> VRAM buffer moves.
