4ddb1bf1 - tegra: mark BPMP driver as little-endian only

Wed, 23 Nov 2022 13:21:16 +0000

tegra: mark BPMP driver as little-endian onlyThe BPMP firmware driver never worked on big-endian kernels, andcannot easily be made portable. Add a dependency to make this clearin case anyone ever wants to try a big-endian kernel on this hardware.Link: https://lore.kernel.org/linux-arm-kernel/Y34FCQ3xTmcjqKRT@orome/Signed-off-by: Arnd Bergmann List of files: /linux-6.15/drivers/firmware/tegra/Kconfig

983de5f9 - firmware: tegra: Add BPMP support

Fri, 19 Aug 2016 17:05:35 +0000

firmware: tegra: Add BPMP supportThe Boot and Power Management Processor (BPMP) is a co-processor foundon Tegra SoCs. It is designed to handle the early stages of the bootprocess and offload power management tasks (such as clocks, resets,powergates, ...) as well as system control services.Compared to the ARM SCPI, the services provided by BPMP are message-based rather than method-based. The BPMP firmware driver provides theservices to transmit data to and receive data from the BPMP. Users canalso register a Message ReQuest (MRQ), for which a service routine willbe run when a corresponding event is received from the firmware.A set of messages, called the BPMP ABI, are specified for a number ofdifferent services provided by the BPMP (such as clocks or resets).Based on work by Sivaram Nair and Joseph Lo.Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/firmware/tegra/Kconfig

ca791d7f - firmware: tegra: Add IVC library

Fri, 19 Aug 2016 17:05:04 +0000

firmware: tegra: Add IVC libraryThe Inter-VM communication (IVC) is a communication protocol which isdesigned for interprocessor communication (IPC) or the communicationbetween the hypervisor and the virtual machine with a guest OS.Message channels are used to communicate between processors. They arebacked by DRAM or SRAM, so care must be taken to maintain coherence ofdata.The IVC library maintains memory-based descriptors for the transmissionand reception channels as well as the data coherence of the counter andpayload. Clients, such as the driver for the BPMP firmware, can use thelibrary to exchange messages with remote processors.Based on work by Peter Newman and Joseph Lo.Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/firmware/tegra/Kconfig
