fbf7e5ce - mailbox: add Samsung Exynos driver

Wed, 15 Jan 2025 14:18:15 +0000

mailbox: add Samsung Exynos driverThe Samsung Exynos mailbox controller, used on Google GS101 SoC, has 16flag bits for hardware interrupt generation and a shared register forpassing mailbox messages. When the controller is used by theACPM interface the shared register is ignored and the mailbox controlleracts as a doorbell. The controller just raises the interrupt to APMafter the ACPM interface has written the message to SRAM.Add support for the Samsung Exynos mailbox controller.Signed-off-by: Tudor Ambarus Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Kconfig

e4b1d67e - mailbox: add Microchip IPC support

Tue, 17 Dec 2024 11:31:34 +0000

mailbox: add Microchip IPC supportAdd a mailbox controller driver for the Microchip Inter-processorCommunication (IPC), which is used to send and receive data betweenprocessors.The driver uses the RISC-V Supervisor Binary Interface (SBI) tocommunicate with software running in machine mode (M-mode) to accessthe IPC hardware block.Additional details on the Microchip vendor extension and the IPCfunction IDs described in the driver can be found in the followingdocumentation:https://github.com/linux4microchip/microchip-sbi-ecall-extensionThis SBI interface in this driver is compatible with the Mi-V Inter-hartCommunication (IHC) IP.Transmitting and receiving data through the mailbox framework is donethrough struct mchp_ipc_msg.Signed-off-by: Valentina Fernandez Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Kconfig

mailbox: Introduce support for T-head TH1520 Mailbox driverThis driver was tested using the drm/imagination GPU driver. It was ableto successfully power on the GPU, by passing a command through mailboxfrom E910 core to E902 that's responsible for powering up the GPU. TheGPU driver was able to read the BVNC version from control registers,which confirms it was successfully powered on.[ 33.957467] powervr ffef400000.gpu: [drm] loaded firmwarepowervr/rogue_36.52.104.182_v1.fw[ 33.966008] powervr ffef400000.gpu: [drm] FW version v1.0 (build6621747 OS)[ 38.978542] powervr ffef400000.gpu: [drm] *ERROR* Firmware failed tobootThough the driver still fails to boot the firmware, the mailbox driverworks when used with the not-yet-upstreamed firmware AON driver.

3f58c1f4 - mailbox: omap: Remove kernel FIFO message queuing

Wed, 10 Apr 2024 13:59:42 +0000

mailbox: omap: Remove kernel FIFO message queuingThe kernel FIFO queue has a couple issues. The biggest issue is thatit causes extra latency in a path that can be used in real-time tasks,such as communication with real-time remote processors.The whole FIFO idea itself looks to be a leftover from before theunified mailbox framework. The current mailbox framework expectsmbox_chan_received_data() to be called with data immediately as itarrives. Remove the FIFO and pass the messages to the mailboxframework directly as part of a threaded IRQ handler.Signed-off-by: Andrew Davis Signed-off-by: Jassi Brar List of files: /linux-6.15/drivers/mailbox/Kconfig
