54e6baf1 - gpu: nova-core: add initial driver stub

Thu, 06 Mar 2025 22:23:30 +0000

gpu: nova-core: add initial driver stubAdd the initial nova-core driver stub.nova-core is intended to serve as a common base for nova-drm (thecorresponding DRM driver) and the vGPU manager VFIO driver, serving as ahard- and firmware abstraction layer for GSP-based NVIDIA GPUs.The Nova project, including nova-core and nova-drm, in the long term,is intended to serve as the successor of Nouveau for all GSP-based GPUs.The motivation for both, starting a successor project for Nouveau anddoing so using the Rust programming language, is documented in detailthrough a previous post on the mailing list [1], an LWN article [2] and atalk from LPC '24.In order to avoid the chicken and egg problem to require a user toupstream Rust abstractions, but at the same time require the Rustabstractions to implement the driver, nova-core kicks off as a driverstub and is subsequently developed upstream.Link: https://lore.kernel.org/dri-devel/Zfsj0_tb-0-tNrJy@cassiopeiae/T/#u [1]Link: https://lwn.net/Articles/990736/ [2]Link: https://youtu.be/3Igmx28B3BQ?si=sBdSEer4tAPKGpOs [3]Reviewed-by: Alexandre Courbot Link: https://lore.kernel.org/r/20250306222336.23482-5-dakr@kernel.orgSigned-off-by: Danilo Krummrich List of files: /linux-6.15/drivers/video/Kconfig

75fa9b7e - video: Add helpers for decoding screen_info

Mon, 12 Feb 2024 09:06:09 +0000

video: Add helpers for decoding screen_infoThe plain values as stored in struct screen_info need to be decodedbefore being used. Add helpers that decode the type of video outputand the framebuffer I/O aperture.Old or non-x86 systems may not set the type of video directly, butonly indicate the presence by storing 0x01 in orig_video_isVGA. Thedecoding logic in screen_info_video_type() takes this into account.It then follows similar code in vgacon's vgacon_startup() to detectthe video type from the given values.A call to screen_info_resources() returns all known resources of thegiven screen_info. The resources' values have been taken from existingcode in vgacon and vga16fb. These drivers can later be converted touse the new interfaces.v2: * return ssize_t from screen_info_resources() * don't call __screen_info_has_lfb() unnecessarilySigned-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20240212090736.11464-2-tzimmermann@suse.de List of files: /linux-6.15/drivers/video/Kconfig

The new helper returns true ifthe adapter has been enabled, and false otherwise.There is the ofonly parameter, which disables output for non-OF-basedframebuffers.

video: Kconfig: move drm and fb into separate menusAt the moment the "Device Drivers / Graphics support" kernel config pagelooks rather messy, with DRM and fbdev driver selections on the samepage, some on the top level Graphics support page, some under theirrespective subsystems.If I'm not mistaken, this is caused by the drivers depending on otherthings than DRM or FB, which causes Kconfig to arrange the options innot-so-neat manner.Both DRM and FB have a main menuconfig option for the whole DRM or FBsubsystem. Optimally, this would be enough to arrange all DRM and FBoptions under the respective subsystem, but for whatever reason thisdoesn't work reliably.This patch adds an explicit submenu for DRM and FB, making it muchclearer which options are related to FB, and which to DRM.Signed-off-by: Tomi Valkeinen Acked-by: Laurent Pinchart Acked-by: Geert Uytterhoeven Acked-by: Rob Clark Reviewed-by: Jingoo Han Acked-by: Daniel Vetter List of files: /linux-6.15/drivers/video/Kconfig
