fe45ab55 - firmware/tegra: Enable Tegra186 BPMP support on Tegra194

Thu, 07 Feb 2019 11:50:06 +0000

firmware/tegra: Enable Tegra186 BPMP support on Tegra194The BPMP implementation on Tegra194 is mostly compatible with theimplementation on Tegra186, so make sure the latter is available whensupport for Tegra194 is enabled.Suggested-by: Timo Alho Reviewed-by: Timo Alho Tested-by: Timo Alho Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/firmware/tegra/Makefile

139251fc - firmware: tegra: add bpmp driver for Tegra210

Thu, 24 Jan 2019 17:03:54 +0000

firmware: tegra: add bpmp driver for Tegra210This patch adds driver for Tegra210 BPMP firmware.The BPMP is a specific processor in Tegra210 chip, which runs firmwarefor assisting in entering deep low power states (suspend to ram), andoffloading DRAM memory clock scaling on some platforms.Based on work by Sivaram Nair Signed-off-by: Timo Alho Acked-by: Jon Hunter Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/firmware/tegra/Makefile

f2381f65 - firmware: tegra: Add BPMP debugfs support

Tue, 03 Oct 2017 06:12:13 +0000

firmware: tegra: Add BPMP debugfs supportTegra power management firmware running on the co-processor (BPMP)implements a simple pseudo file system akin to debugfs. The filesystem can be used for debugging purposes to examine and change thestatus of selected resources controlled by the firmware (such asclocks, resets, voltages, powergates, ...).Add support to "mirror" the firmware's file system to debugfs. Atboot, query firmware for a list of all possible files and createcorresponding debugfs entries. Read/write of individual files isimplemented by sending a Message ReQuest (MRQ) that passes the fullfile path name and data to firmware via DRAM.Signed-off-by: Timo Alho Reviewed-by: Jon Hunter Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/firmware/tegra/Makefile

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/Makefile

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/Makefile
