config OMAP_REMOTEPROC
tristate "OMAP remoteproc support"
remoteproc/omap: Add support for DRA7xx remote processors DRA7xx/AM57xx SoCs have two IPU and up to two DSP processor subsystems for offloading different computation algorithms. The IPU processor subsystem contains dual-core ARM Cortex-M4 processors, and is very similar to those on OMAP5. The DSP processor subsystem is based on the TI's standard TMS320C66x DSP CorePac core. Support has been added to the OMAP remoteproc driver through new DRA7xx specific compatibles for properly probing and booting all the different processor subsystem instances on DRA7xx/AM57xx SoCs - IPU1, IPU2, DSP1 & DSP2. A build dependency with SOC_DRA7XX is added to enable the driver to be built in DRA7xx-only configuration. The DSP boot address programming needed enhancement for DRA7xx as the boot register fields are different on DRA7 compared to OMAP4 and OMAP5 SoCs. The register on DRA7xx contains additional fields within the register and the boot address bit-field is right-shifted by 10 bits. The internal memory parsing logic has also been updated to compute the device addresses for the L2 RAM for DSP devices using relative addressing logic, and to parse two additional RAMs at L1 level - L1P and L1D. This allows the remoteproc driver to support loading into these regions for a small subset of firmware images requiring as such. The most common usage would be to use the L1 programmable RAMs as L1 Caches. The firmware lookup logic also has to be adjusted for DRA7xx as there are (can be) more than one instance of both the IPU and DSP remote processors for the first time in OMAP4+ SoCs.

remoteproc: k3-dsp: Add a remoteproc driver of K3 C66x DSPs The Texas Instrument's K3 J721E SoCs have two C66x DSP Subsystems in MAIN voltage domain that are based on the TI's standard TMS320C66x DSP CorePac module. Each subsystem has a Fixed/Floating-Point DSP CPU, with 32 KB each of L1P & L1D SRAMs that can be configured and partitioned as either RAM and/or Cache, and 288 KB of L2 SRAM with 256 KB of memory configurable as either RAM and/or Cache. The CorePac also includes an Internal DMA (IDMA), External Memory Controller (EMC), Extended Memory Controller (XMC) with a Region Address Translator (RAT) unit for 32-bit to 48-bit address extension/translations, an Interrupt Controller (INTC) and a Powerdown Controller (PDC). A new remoteproc module is added to perform the device management of these DSP devices. The support is limited to images using only external DDR memory at the moment, the loading support to internal memories and any on-chip RAM memories will be added in a subsequent patch. RAT support is also left for a future patch, and as such the reserved memory carveout regions are all expected to be using memory regions within the first 2 GB. Error Recovery and Power Management features are not currently supported. The C66x remote processors do not have an MMU, and so require fixed memory carveout regions matching the firmware image addresses. Support for this is provided by mandating multiple memory regions to be attached to the remoteproc device. The first memory region will be used to serve as the DMA pool for all dynamic allocations like the vrings and vring buffers. The remaining memory regions are mapped into the kernel at device probe time, and are used to provide address translations for firmware image segments without the need for any RSC_CARVEOUT entries. Any firmware image using memory outside of the supplied reserved memory carveout regions will be errored out. The driver uses various TI-SCI interfaces to talk to the System Controller (DMSC) for managing configuration, power and reset management of these cores. IPC between the A72 cores and the DSP cores is supported through the virtio rpmsg stack using shared memory and OMAP Mailboxes.

subsystems on various TI K3 family of SoCs through the remote

remoteproc: k3-r5: Add a remoteproc driver for R5F subsystem The TI K3 family of SoCs typically have one or more dual-core Arm Cortex R5F processor clusters/subsystems (R5FSS). This R5F subsystem/cluster can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. This subsystem has 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - TCMA and TCMB (further interleaved into two banks). The subsystem does not have an MMU, but has a Region Address Translater (RAT) module that is accessible only from the R5Fs for providing translations between 32-bit CPU addresses into larger system bus addresses. Add a remoteproc driver to support this subsystem to be able to load and boot the R5F cores primarily in LockStep mode. The code also includes the base support for Split mode. Error Recovery and Power Management features are not currently supported. Loading support includes the internal TCMs and DDR. RAT support is left for a future patch, and as such the reserved memory carveout regions are all expected to be using memory regions within the first 2 GB. The R5F remote processors do not have an MMU, and so require fixed memory carveout regions matching the firmware image addresses. Support for this is provided by mandating multiple memory regions to be attached to the remoteproc device. The first memory region will be used to serve as the DMA pool for all dynamic allocations like the vrings and vring buffers. The remaining memory regions are mapped into the kernel at device probe time, and are used to provide address translations for firmware image segments without the need for any RSC_CARVEOUT entries. Any firmware image using memory outside of the supplied reserved memory carveout regions will be errored out. The R5F processors on TI K3 SoCs require a specific sequence for booting and shutting down the processors. This sequence is also dependent on the mode (LockStep or Split) the R5F cluster is configured for. The R5F cores have a Memory Protection Unit (MPU) that has a default configuration that does not allow the cores to run out of DDR out of reset. This is resolved by using the TCMs for boot-strapping code that applies the appropriate executable permissions on desired DDR memory. The loading into the TCMs requires that the resets be released first with the cores in halted state. The Power Sleep Controller (PSC) module on K3 SoCs requires that the cores be in WFI/WFE states with no active bus transactions before the cores can be put back into reset. Support for this is provided by using the newly introduced .prepare() and .unprepare() ops in the remoteproc core. The .prepare() ops is invoked before any loading, and the .unprepare() ops is invoked after the remoteproc resource cleanup. The R5F core resets are deasserted in .prepare() and asserted in .unprepare(), and the cores themselves are started and halted in .start() and .stop() ops. This ensures symmetric usage and allows the R5F cores state machine to be maintained properly between using the sysfs 'state' variable, bind/unbind and regular module load/unload flows. The subsystem is represented as a single remoteproc in LockStep mode, and as two remoteprocs in Split mode. The driver uses various TI-SCI interfaces to talk to the System Controller (DMSC) for managing configuration, power and reset management of these cores. IPC between the A53 cores and the R5 cores is supported through the virtio rpmsg stack using shared memory and OMAP Mailboxes. The AM65x SoCs typically have a single R5FSS in the MCU voltage domain. The J721E SoCs uses a slightly revised IP and typically have three R5FSSs, with one cluster present within the MCU voltage domain (MCU_R5FSS0), and the remaining two clusters present in the MAIN voltage domain (MAIN_R5FSS0 and MAIN_R5FSS1). The integration of these clusters on J721E SoC is also slightly different in that these IPs do support an actual local reset line, while they are a no-op on AM65x SoCs.
