| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "nomodeset" kernel cmdline parameter is handled by the vgacon driver but the exported vgacon_text_force() symbol is only used by DRM drivers. It makes much more sense for the parameter logic to be in the subsystem of the drivers that are making use of it. Let's move the vgacon_text_force() function and related logic to the DRM subsystem. While doing that, rename it to drm_firmware_drivers_only() and make it return true if "nomodeset" was used and false otherwise. This is a better description of the condition that the drivers are testing for.

| | | | | | | | | | | | | | | Current (and older) Simics models for the Bochs VGA used the wrong PCI vendor ID (0x4321 instead of 0x1234). Although this can hopefully be fixed in the future, it is a problem for users of the current version, not the least because to update the device ID the BIOS has to be rebuilt in order to see BIOS output.

* drm/shmem-helper: Switch to vmf_insert_pfnDaniel Vetter2021-08-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to stop gup, which isn't the case if we use vmf_insert_page and VM_MIXEDMAP, because that does not set pte_special. The motivation here is to stop get_user_pages from working on buffer object 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 least ttm and could also cause trouble with cma allocations. In both cases becaue we can't move/reuse these pages anymore. Now get_user_pages fails when the memory isn't considered "normal", like with VM_PFNMAP and using vm_insert_pfn. For consistency across all dma-buf I'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 it closes an actual bug (ttm gets really badly confused when there's suddenly pinned pages where it thought it can move them). cma allcoations already use VM_PFNMAP (because that's what dma_mmap is using underneath), as is anything that's using remap_pfn_range. Worst case we have to revert this patch for shmem helpers if it breaks something, but I hope that's not the case. On the ttm side we've also had some fallout that 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 of buffers to userspace on !MMU platforms we'd need to use the cma helpers for these drivers on those platforms. As-is this wont work. Also not exactly sure why vm_insert_page doesn't go boom, because that definitely wont fly in practice since the pages are non-contig to begin with. v4: Explain the entire motivation a lot more (Thomas) Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20210812131412.2487363-2-daniel.vetter@ffwll.ch

* drivers/firmware: consolidate EFI framebuffer setup for all archesJavier Martinez Canillas2021-07-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The simpledrm driver is a DRM driver for simple-framebuffer framebuffers as provided by the kernel's boot code. This driver enables basic graphical output on many different graphics devices that are provided by the platform (e.g., EFI, VESA, embedded framebuffers). With the kernel's simple-framebuffer infrastructure, the kernel receives a pre-configured framebuffer from the system (i.e., firmware, boot loader). It creates a platform device to which simpledrm attaches. The system's framebuffer consists of a memory range, size and format. Based on these values, simpledrm creates a DRM devices. No actual modesetting is possible. A firmware framebuffer might also be specified via device-tree files. If no device platform data is given, try the DT device node. Make sure required hardware clocks and regulators are enabled while the firmware framebuffer is in use. The basic code has been taken from the simplefb driver and adapted to DRM. Clocks are released automatically via devres helpers. The drivers displays a console on simpledrm's framebuffer. The default framebuffer format is being used. v4: * disable simplefb if simpledrm has been selected (Maxime) v3: * add disable function that clears screen to black (Daniel) * set shadow buffering only for fbdev emulation * set platform-driver data during device creation v2: * rename driver to simpledrm * add dri-devel to MAINTAINERS entry * put native format first in primary-plane format list (Daniel) * inline simplekms_device_cleanup() (Daniel) * use helpers for shadow-buffered planes * fix whitespace errors * add Device Tree match table * clean-up parser wrappers * use strscpy() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> # fbdev support Acked-by: Maxime Ripard <maxime@cerno.tech> Tested-by: nerdopolis <bluescreen_avenger@verizon.net> Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-5-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-6-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-7-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-8-tzimmermann@suse.de Link: https://patchwork.freedesktop.org/patch/msgid/20210430105840.30515-9-tzimmermann@suse.de

* | drm: Use USB controller's DMA mask when importing dmabufsThomas Zimmermann2021-03-111-8/+36
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB devices cannot perform DMA and hence have no dma_mask set in their device structure. Therefore importing dmabuf into a USB-based driver fails, which breaks joining and mirroring of display in X11. For USB devices, pick the associated USB controller as attachment device. This allows the DRM import helpers to perform the DMA setup. If the DMA controller does not support DMA transfers, we're out of luck and cannot import. Our current USB-based DRM drivers don't use DMA, so the actual DMA device is not important.
