Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

fbcon: Increase maximum font width x height to 64 x 128

2024-03-16T07:29:48+00:00

By using bitmaps we actually support whatever size we would want, but the console currently limits fonts to 64x128 (which gives 60x16 text on 4k screens), so we don't need more for now, and we can easily increase later. Signed-off-by: Samuel Thibault Signed-off-by: Helge Deller

video/sticore: Store ROM device in STI struct

2024-01-12T11:38:37+00:00

Store the ROM's parent device in each STI struct, so we can associate the STI framebuffer with a device. The new field will eventually replace the fbdev subsystem's info field, which the function fb_is_primary_device() currently requires to detect the firmware's output. By using the device instead of the framebuffer info, a later patch can generalize the helper for use in non-fbdev code. Signed-off-by: Thomas Zimmermann Signed-off-by: Helge Deller

sticon/parisc: Fix STI console on 64-bit only machines

2023-06-30T15:14:14+00:00

Fix the STI console to be able to execute either the 64-bit STI ROM code or the 32-bit STI ROM code. This is necessary on 64-bit only machines (e.g. C8000 workstation) which otherwise won't show the STI text console with HP graphic cards like Visualize-FX5/FX10/FXe. Note that when calling 32-bit code from a 64-bit kernel one needs to copy contents on the CPU stack from high memory down below the 4GB limit.

sticon/parisc: Allow 64-bit STI calls in PDC firmware abstration

2023-06-30T15:14:14+00:00

Some 64-bit machines require us to call the STI ROM in 64-bit mode, e.g. with the VisFXe graphic card. This patch allows drivers to use such 64-bit calling conventions. Tested-by: John David Anglin Signed-off-by: Helge Deller

arch/parisc: Implement fb_is_primary_device() under arch/parisc

2023-04-20T08:04:58+00:00

Move PARISC's implementation of fb_is_primary_device() into the architecture directory. This the place of the declaration and where other architectures implement this function. No functional changes.

video: Move HP PARISC STI core code to shared location

2023-04-20T08:04:51+00:00

STI core files have been located in console and fbdev code. Move the source code and header to the directories for video helpers. Also update the config and build rules such that the code depends on the config symbol CONFIG_STI_CORE, which STI console and STI framebuffer select automatically. Cleans up the console makefile and prepares PARISC to implement fb_is_primary_device() within the arch/ directory. No functional changes.
