[RFC][PATCH 1/1] drm/amdkfd: Remove redundant pdd validation
by Maninder Singh 09 Jul '15

09 Jul '15

pdd is already dereferenced before this check. So it is redundtant to validate pdd here.

[Bug 100541] New: Since 4.1, the mouse cursor is corrupted after suspend/resume
by bugzilla-daemon＠bugzilla.kernel.org 09 Jul '15

https://bugzilla.kernel.org/show_bug.cgi?id=100541 Bug ID: 100541 Summary: Since 4.1, the mouse cursor is corrupted after suspend/resume Product: Drivers Version: 2.5 Kernel Version: 4.1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: casteyde.christian(a)free.fr Regression: No When I suspend the laptop and resume it, X.org shows the screen locker fine but: a. the mouse cursor is now a square full of random colored pixels; b. switching to console VT shows the whole screen filled with random colored pixels until the text mode is set up. After switching back to X (vt7), everything is nice. The cursor is also restored when after login to KDE, probably the WM changes it. It used to work fine with previous kernels (last working is 4.0.6). Therefore I think something was broken when restoring the graphic state. Hardware: AMD turks, Core i7, 64bits. lspci -v: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) Subsystem: Acer Incorporated [ALI] Device 050e

Hi, I am getting the following warning when I switch to the text console from X. I do not know when this has started because I have noticed that only now (in 4.1 kernel). I can try some older kernels if this is useful. I have tried to instrument drm_wait_one_vblank and dump drm_vblank_count before the wait_event and the value when it returns (see the diff below) and it seems to be increasing with new switching to the text console: $ dmesg | grep XXX [ 6.531908] XXX: last:36 [ 6.545852] XXX: drm_vblank_count:37 [ 9.038658] XXX: last:186 [ 9.051332] XXX: drm_vblank_count:187 [ 9.051424] XXX: last:187 [ 9.068036] XXX: drm_vblank_count:188 [ 16.962193] XXX: last:660 [ 16.968683] XXX: drm_vblank_count:661 [ 30.592874] XXX: last:1476 [ 30.598656] XXX: drm_vblank_count:1477 [ 30.598768] XXX: last:1477 [ 30.615339] XXX: drm_vblank_count:1478 [ 37.313338] XXX: last:1879 [ 37.330102] XXX: drm_vblank_count:1880 [ 39.726809] XXX: last:2023 [ 39.735265] XXX: drm_vblank_count:2024 [ 39.735375] XXX: last:2024 [ 39.752094] XXX: drm_vblank_count:2025 [ 60.842401] XXX: last:3287 [ 60.848437] XXX: drm_vblank_count:3288 [ 62.149546] XXX: last:3365 [ 62.151277] XXX: drm_vblank_count:3366 [ 62.151411] XXX: last:3366 [ 62.249376] XXX: drm_vblank_count:3366 [ 92.198305] XXX: last:5160 [ 92.297091] XXX: drm_vblank_count:5160 [ 93.822331] XXX: last:5253 [ 93.922153] XXX: drm_vblank_count:5253 [ 93.922424] XXX: last:5254 [ 94.022213] XXX: drm_vblank_count:5254 [ 100.877802] XXX: last:5665 [ 100.974740] XXX: drm_vblank_count:5665 I am sorry about the lack of information in this report but I am really not sure what might be helpful.

[PATCH 0/3] drm/ttm: hard to swim in an empty pool
by Jérôme Glisse 08 Jul '15

08 Jul '15

So it seems there was several issue with the various ttm pool. The obvious one is fixed in patch 2 where the always empty pool syndrom is addressed. However the pool size are kind of crazy and because before some pool were never actualy fill we might never have experience the hill effect of the crazy maximum limit. This is what is addressed by first patch. Last patch cook it up further so that under memory pressure the pool size is divided by 2 each time a shrinker is run on a pool. There is a timeout to restore the pool size on next allocation. Idea here is that memory should not last and if it last then shrinker will keep minimize the pool size and anyway thing are probably already sluggish once we it the shrinker path. Of course because this fix thing in ttm memory allocation this need careful testing. So before pushing anything i would like to see more people testing this. Cheers, Jérôme

[PATCH 1/2] drm: rockchip: Don't pass DRM fake offset to dma-api
by Ørjan Eide 07 Jul '15

07 Jul '15

Set vm_pgoff to 0 after using it to look up the GEM node, before passing it on rockchip_gem_mmap_buf() where the offset must be from the start of the buffer. Passing in the fake offset currently works because the dma_mmap_attrs implementation that is used for this device, arm_iommu_mmap_attrs, ignores the offset completely.

Performance is just horrible with tons of dips when playing TF2, and probably other Valve games. Polygon count just makes it too heavy to what it used to be, dipping down to 20FPS or so when moving objects and such. I don't have time to bisect, don't even know how much longer I will be using this R9 270X, so any tests I can do without a recompile I can try.

[PATCH v2 0/2] drm/nouveau: option for staging ioctls and new GEM_SET_TILING ioctl
by Alexandre Courbot 06 Jul '15

06 Jul '15

Second version of this patchset addressing Ben's comments and fixing a few extra things. This patchset proposes to introduce a "staging" module option to dynamically enable features (mostly ioctls) that are merged but may be refined before they are declared "stable". The second patch illustrates the use of this staging option with the SET_TILING ioctl, which can be used to specify the tiling options of a PRIME-imported buffer. The staging parameter will allow us (particularly, us at NVIDIA) to experiment more freely with new features and avoid carrying out-of-tree patches for long periods of time. To prevent abuse, the number of staging ioctls is limited to 8 (range 0x98 to 0xa0) that are to be recycled as staging ioctls become stable and are assigned a final number. Changes since v1: - Use one module option per staging ioctl - Only allow GEM_SET_TILING to be called on dma-buf imported buffers - Move the code setting nvkm_mem::memtype into its own function to avoid duplicating code Alexandre Courbot (1): drm/nouveau: placeholders for staging ioctls Ari Hirvonen (1): drm/nouveau: add GEM_SET_TILING staging ioctl drm/nouveau/nouveau_bo.c | 18 ++++++++++++ drm/nouveau/nouveau_bo.h | 2 ++ drm/nouveau/nouveau_drm.c | 7 +++++ drm/nouveau/nouveau_gem.c | 58 ++++++++++++++++++++++++++++++++++++++ drm/nouveau/nouveau_gem.h | 2 ++ drm/nouveau/nouveau_ttm.c | 13 +-------- drm/nouveau/uapi/drm/nouveau_drm.h | 11 ++++++++ 7 files changed, 99 insertions(+), 12 deletions(-) -- 2.4.2
