The SMC firmware included in macOS 27 changed the size of BCF0 key from 4 to 1 bytes. This key is used for indicating that battery state is critically low. Reviewed-by: Sven Peter <sven@kernel.org> Signed-off-by: Sasha Finkelstein <k@chaosmail.tech>
Certain Broadcom bluetooth chips (bcm4377/bcm4378/bcm438) need ACL streams carrying audio to be set as "high priority" using a vendor specific command to prevent 10-ish second-long dropouts whenever something does a device scan. This patch sends the command when the socket priority is set to TC_PRIO_INTERACTIVE, as BlueZ does for audio. Signed-off-by: Sasha Finkelstein <fnkl.kernel@gmail.com>
The current approach of silently disabling all rust drivers if the toolchain is missing results in users that try to compile their own kernels getting a "successful" build and then being confused about where did their drivers go. In comparison, missing openssl results in a build failure, not a disappearance of everything that depends on it. This also means that allyesconfig will depend on rust, but since the rust experiment concluded with "rust is here to stay", i believe that allyesconfig should be building rust drivers too.

Apple M3 Pro and Max devices are using 'gp00' keys for GPIO in addition to 'gP00' keys. Add a second compatible to handle this keys with an additional macsmc-gpio instance. Signed-off-by: Janne Grunau <j@jannau.net>
Add support for SMC GPIO keys with a lower letter 'p' via the "apple,smc-low-gpio" compatible. This adds support for a second macsmc-gpio controller using 'gp00' keys. These keys are used on Apple M3 Pro and Max MacBooks in the controller for keyboard and trackpad and for the built-in DisplayPort to HDMI converter. Signed-off-by: Janne Grunau <j@jannau.net>

Since immediate mode was enabled, unmapping a GPU VA can defer drm_gpuvm_bo destruction until drm_gpuvm_bo_deferred_cleanup() is called. The GEM bind and unbind paths drain that list, but Vm::drop() unmaps the remaining user ranges without doing so. Drain the deferred list after both teardown unmaps. Otherwise a deferred drm_gpuvm_bo retains the imported GEM and dma-buf after its DRM file is closed, leaving its backing pages pinned. Fixes: 2aeee2d ("drm/asahi: Switch gpuvm to DRM_GPUVM_IMMEDIATE_MODE") Signed-off-by: DesktopECHO <33142753+DesktopECHO@users.noreply.github.com>

This is a hardcoded charge threshold feature present in firmware 13.0 or newer. Userspace settings are rounded to one of the two possible behaviors. Since macOS Sequoia firmware, CHLS replaced CHWA and now allows an arbitrary end charge threshold to be configured. Prefer CHWA over CHLS since the SMC firmware from iBoot-10151.1.1 (macOS 14.0) is not compatible with our CHGLS usage. It was working with the SMC firmware from iBoot-10151.121.1 (macOS 14.5).
