Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

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

clk: bcm: rpi: Maximize V3D clock

2025-09-21T16:09:51+00:00

Although minimizing the clock rate is the best for most scenarios, as stated in commit 4d85abb0fb8e ("clk: bcm: rpi: Enable minimize for all firmware clocks"), when it comes to the GPU, it's ideal to have the maximum rate allowed. Add an option to maximize a firmware clock's rate when the clock is enabled and set this option for V3D. Signed-off-by: Maíra Canal Signed-off-by: Stephen Boyd

clk: bcm: rpi: Turn firmware clock on/off when preparing/unpreparing

2025-09-21T16:09:34+00:00

Currently, when we prepare or unprepare RPi's clocks, we don't actually enable/disable the firmware clock. This means that `clk_disable_unprepare()` doesn't actually change the clock state at all, nor does it lowers the clock rate. From the Mailbox Property Interface documentation [1], we can see that we should use `RPI_FIRMWARE_SET_CLOCK_STATE` to set the clock state off/on. Therefore, use `RPI_FIRMWARE_SET_CLOCK_STATE` to create a prepare and an unprepare hook for RPi's firmware clock. As now the clocks are actually turned off, some of them are now marked CLK_IS_CRITICAL, as those are required to be on during the whole system operation.

clk: bcm: rpi: Add missing logs if firmware fails

2025-09-21T16:09:21+00:00

In contrary to raspberrypi_fw_set_rate(), the ops for is_prepared() and recalc_rate() silently ignore firmware errors by just returning 0. Since these operations should never fail, add at least error logs to inform the user. Signed-off-by: Stefan Wahren Signed-off-by: Maíra Canal Signed-off-by: Stephen Boyd
