[Nouveau] [PATCH 1/2] Revert "bus: remove cpu_coherent flag"
This reverts commit 01bbcb69f80e1058395b737ae399c6f4ef48691b.
The commit caused fence timeouts within nvc0_screen_destroy and most likely
other places as well.
The most obvious effect is, that userspace processes take minutes to actually
quit.

[Nouveau] [PATCH 2/2] nouveau: Fix compile error due to bad include
Every other *_drm.h does #include "drm.h". Something else is wrong.

By the way, Alexandre, I believe Martin was reporting issues like this on his TK1 before this change as well. Probably worth investigating - sounds like there's a wider issue with TTM_PL_FLAG_UNCACHED and/or force_coherent.> >> >> Signed-off-by: Karol Herbst <karolherbst at gmail.com> >> --- >> drm/nouveau/include/nvkm/core/device.h | 1 + >> drm/nouveau/nouveau_bo.c | 3 ++- >> drm/nouveau/nvkm/engine/device/pci.c | 1 + >> drm/nouveau/nvkm/engine/device/tegra.c | 1 + >> lib/include/nvif/os.h | 6 ++++++ >> 5 files changed, 11 insertions(+), 1 deletion(-) >> >> diff --git a/drm/nouveau/include/nvkm/core/device.h b/drm/nouveau/include/nvkm/core/device.h >> index 7ea8aa7..6bc712f 100644 >> --- a/drm/nouveau/include/nvkm/core/device.h >> +++ b/drm/nouveau/include/nvkm/core/device.h >> @@ -175,6 +175,7 @@ struct nvkm_device_func { >> void (*fini)(struct nvkm_device *, bool suspend); >> resource_size_t (*resource_addr)(struct nvkm_device *, unsigned bar); >> resource_size_t (*resource_size)(struct nvkm_device *, unsigned bar); >> + bool cpu_coherent; >> }; >> >> struct nvkm_device_quirk { >> diff --git a/drm/nouveau/nouveau_bo.c b/drm/nouveau/nouveau_bo.c >> index 528bdef..6887d0a 100644 >> --- a/drm/nouveau/nouveau_bo.c >> +++ b/drm/nouveau/nouveau_bo.c >> @@ -209,7 +209,8 @@ nouveau_bo_new(struct drm_device *dev, int size, int align, >> nvbo->tile_flags = tile_flags; >> nvbo->bo.bdev = &drm->ttm.bdev; >> >> - nvbo->force_coherent = flags & TTM_PL_FLAG_UNCACHED; >> + if (!nvxx_device(&drm->device)->func->cpu_coherent) >> + nvbo->force_coherent = flags & TTM_PL_FLAG_UNCACHED; >> >> nvbo->page_shift = 12; >> if (drm->client.vm) { >> diff --git a/drm/nouveau/nvkm/engine/device/pci.c b/drm/nouveau/nvkm/engine/device/pci.c >> index b1b6932..62ad030 100644 >> --- a/drm/nouveau/nvkm/engine/device/pci.c >> +++ b/drm/nouveau/nvkm/engine/device/pci.c >> @@ -1614,6 +1614,7 @@ nvkm_device_pci_func = { >> .fini = nvkm_device_pci_fini, >> .resource_addr = nvkm_device_pci_resource_addr, >> .resource_size = nvkm_device_pci_resource_size, >> + .cpu_coherent = !IS_ENABLED(CONFIG_ARM), >> }; >> >> int >> diff --git a/drm/nouveau/nvkm/engine/device/tegra.c b/drm/nouveau/nvkm/engine/device/tegra.c >> index 939682f..9b638bd 100644 >> --- a/drm/nouveau/nvkm/engine/device/tegra.c >> +++ b/drm/nouveau/nvkm/engine/device/tegra.c >> @@ -245,6 +245,7 @@ nvkm_device_tegra_func = { >> .fini = nvkm_device_tegra_fini, >> .resource_addr = nvkm_device_tegra_resource_addr, >> .resource_size = nvkm_device_tegra_resource_size, >> + .cpu_coherent = false, >> }; >> >> int >> diff --git a/lib/include/nvif/os.h b/lib/include/nvif/os.h >> index b45a186..2f34c5a 100644 >> --- a/lib/include/nvif/os.h >> +++ b/lib/include/nvif/os.h >> @@ -124,6 +124,12 @@ typedef dma_addr_t resource_size_t; >> #define __printf(a,b) >> #define __user >> >> +#if defined(CONFIG_ARM) >> +#define IS_ENABLED_CONFIG_ARM 1 >> +#else >> +#define IS_ENABLED_CONFIG_ARM 0 >> +#endif >> + >> #if defined(CONFIG_IOMMU_API) >> #define IS_ENABLED_CONFIG_IOMMU_API 1 >> #else >> -- >> 2.10.0 >> >> _______________________________________________ >> Nouveau mailing list >> Nouveau at lists.freedesktop.org >> https://lists.freedesktop.org/mailman/listinfo/nouveau > _______________________________________________ > Nouveau mailing list > Nouveau at lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/nouveau

In there we have the respective header alongside the nouveau_drm.h one. One workaround is to track drm.h in the nouveau repo, with another to adjust KBUILD_OPTS to honour the upstream one. KBUILD_OPTS += KCPPFLAGS="-I$(LINUXDIR)/include/uapi/drm" The above (untested) sounds like the better solution imho. Regards, Emil
