8b93d1d7 - drm/shmem-helper: Switch to vmf_insert_pfn

Thu, 12 Aug 2021 13:14:10 +0000

drm/shmem-helper: Switch to vmf_insert_pfnWe want to stop gup, which isn't the case if we use vmf_insert_pageand VM_MIXEDMAP, because that does not set pte_special.The motivation here is to stop get_user_pages from working on bufferobject mmaps in general. Quoting some discussion with Thomas:On Thu, Jul 22, 2021 at 08:22:43PM +0200, Thomas Zimmermann wrote:> Am 13.07.21 um 22:51 schrieb Daniel Vetter:> > We want to stop gup, which isn't the case if we use vmf_insert_page>> What is gup?get_user_pages. It pins memory wherever it is, which badly wreaks at leastttm and could also cause trouble with cma allocations. In both casesbecaue we can't move/reuse these pages anymore.Now get_user_pages fails when the memory isn't considered "normal", likewith VM_PFNMAP and using vm_insert_pfn. For consistency across all dma-bufI'm trying (together with Christian König) to roll this out everywhere,for fewer surprises.E.g. for 5.14 iirc we merged a patch to do the same for ttm, where itcloses an actual bug (ttm gets really badly confused when there's suddenlypinned pages where it thought it can move them).cma allcoations already use VM_PFNMAP (because that's what dma_mmap isusing underneath), as is anything that's using remap_pfn_range. Worst casewe have to revert this patch for shmem helpers if it breaks something, butI hope that's not the case. On the ttm side we've also had some falloutthat we needed to paper over with clever tricks.v2: With this shmem gem helpers now definitely need CONFIG_MMU (0day)v3: add more depends on MMU. For usb drivers this is a bit awkward,but really it's correct: To be able to provide a contig mapping ofbuffers to userspace on !MMU platforms we'd need to use the cmahelpers for these drivers on those platforms. As-is this wont work.Also not exactly sure why vm_insert_page doesn't go boom, because thatdefinitely wont fly in practice since the pages are non-contig tobegin with.v4: Explain the entire motivation a lot more (Thomas)Acked-by: Thomas Zimmermann Signed-off-by: Daniel Vetter Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Thomas Zimmermann Cc: David Airlie Cc: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20210812131412.2487363-2-daniel.vetter@ffwll.ch List of files: /linux-6.15/drivers/gpu/drm/udl/Kconfig

5d50bd44 - drm/udl: Make udl driver depend on CONFIG_USB

Mon, 06 Jan 2020 14:10:16 +0000

drm/udl: Make udl driver depend on CONFIG_USBThe udl driver for DisplayLink devices depends on support for host-sideUSB controllers, which is enabled with CONFIG_USB. Plain USB support asgiven by CONFIG_USB_SUPPORT is not sufficient.This patch changes dependencies for udl to depend on CONFIG_USB, insteadof CONFIG_USB_SUPPORT. Users will have to enable CONFIG_USB and select aUSB host controller. With this change udl dependencies work the same wayas dependencies for PCI drivers.Signed-off-by: Thomas Zimmermann Acked-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20200106141016.9562-1-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/udl/Kconfig

08b22f65 - drm/udl: Switch to SHMEM

Thu, 07 Nov 2019 09:43:06 +0000

drm/udl: Switch to SHMEMUdl's GEM code and the generic SHMEM are almost identical. Replacethe former with SHMEM. The dmabuf support in udl is being replacedwith generic GEM PRIME functions.The main difference is in the caching flags for mmap pages. Bydefault, SHMEM always sets (uncached) write combining. In udl'smemory management code, only imported buffers use write combining.Memory pages of locally created buffer objects are mmap'ed withcaching enabled. To keep the optimization, udl provides its ownmmap function for GEM objects where it fixes up the mapping flags.v3: - restore udl vmap that enables cachingv2: - remove obsolete code in a separate patchSigned-off-by: Thomas Zimmermann Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20191107094307.19870-4-tzimmermann@suse.de List of files: /linux-6.15/drivers/gpu/drm/udl/Kconfig

92b6f89f - drm: Add separate Kconfig option for fbdev helpers

Tue, 08 Oct 2013 15:44:47 +0000

drm: Add separate Kconfig option for fbdev helpersFor drivers which might want to disable fbdev legacy support.Select the new option in all drivers for now, so this shouldn't resultin any change. Drivers need some work anyway to make fbdev supportoptional (if they have it implemented, that is), so the recommendedway to expose this is by adding per-driver options. At least as longas most drivers don't support disabling the fbdev support.v2: Update for new drm drivers msm and rcar-du. Note that Rob's msmdriver can already take advantage of this, which allows us to buildmsm without any fbdev depencies in the kernel!v3: Move the MODULE_* stuff from the fbdev helper file todrm_crtc_helper.c.Cc: David Herrmann Cc: Rob Clark Reviewed-by: Rob Clark Acked-by: Dave Airlie Reviewed-by: Chon Ming Lee Signed-off-by: Daniel Vetter List of files: /linux-6.15/drivers/gpu/drm/udl/Kconfig
