caeff9a3 - bhnd(4): implement MIPS and PCI(e) interrupt support

Tue, 21 Nov 2017 23:15:20 +0000

bhnd(4): implement MIPS and PCI(e) interrupt supportOn BHND MIPS SoCs, this replaces the use of hard-coded MIPS IRQ#s in thecommon bhnd(4) core drivers; we now register an INTRNG child PIC thathandles routing of backplane interrupt vectors via the MIPS core.On BHND PCI devices, backplane interrupt vectors are now routed to thePCI/PCIe host bridge core when bus_setup_intr() is called, where they aredispatched by the PCI core via a host interrupt (e.g. INTx/MSI).The bhndb(4) bridge driver tracks registered interrupt handlers for thebridged bhnd(4) devices and manages backplane interrupt routing, whiledelegating actual bus interrupt setup/teardown to the parent bus on behalfof the bridged cores.Approved by: adrian (mentor, implicit)Sponsored by: The FreeBSD FoundationDifferential Revision: https://reviews.freebsd.org/D12518 List of files: /freebsd-12.1/sys/mips/broadcom/files.broadcom

77cb4d3e - bhnd(4): Unify NVRAM/SPROM parsing, implement compact SPROM layout encoding.

Sat, 26 Nov 2016 23:22:32 +0000

bhnd(4): Unify NVRAM/SPROM parsing, implement compact SPROM layout encoding.- Defined an abstract NVRAM I/O API (bhnd_nvram_io), decoupling NVRAM/SPROM parsing from the actual underlying NVRAM data provider (e.g. CFE firmware devices).- Defined an abstract NVRAM data API (bhnd_nvram_data), decoupling higher-level NVRAM operations (indexed lookup, data conversion, etc) from the underlying NVRAM file format parsing/serialization.- Implemented a new high-level bhnd_nvram_store API, providing indexed variable lookup, pending write tracking, etc on top of an arbitrary bhnd_nvram_data instance.- Migrated all bhnd(4) NVRAM device drivers to the common bhnd_nvram_store API.- Implemented a common bhnd_nvram_val API for parsing/encoding NVRAM variable values, including applying format-specific behavior when converting to/from the NVRAM string representations.- Dropped the now unnecessary bhnd_nvram driver, and moved the broadcom/mips-specific CFE NVRAM driver out into sys/mips/broadcom.- Implemented a new nvram_map file format: - Variable definitions are now defined separately from the SPROM layout. This will also allow us to define CIS tuple NVRAM mappings referencing the common NVRAM variable definitions. - Variables can now be defined within arbitrary named groups. - Textual descriptions and help information can be defined inline for both variables and variable groups. - Implemented a new, compact encoding of SPROM image layout offsets.- Source-level (but not build system) support for building the NVRAM file format APIs (bhnd_nvram_io, bhnd_nvram_data, bhnd_nvram_store) as a userspace library.The new compact SPROM image layout encoding is loosely modeled on Appledyld compressed LINKEDIT symbol binding opcodes; it provides a compactstate-machine encoding of the mapping between NVRAM variables and the SPROMimage offset, mask, and shift instructions necessary to decode or encodethe SPROM variable data.The compact encoding reduces the size of the generated SPROM layout datafrom roughly 60KB to 3KB. The sequential nature SPROM layout opcode tablesalso simplify iteration of the SPROM variables, as it's no longerneccessary to iterate the full NVRAM variable definition table, butinstead simply scan the SPROM revision's layout opcode table.Approved by: adrian (mentor)Differential Revision: https://reviews.freebsd.org/D8645 List of files: /freebsd-12.1/sys/mips/broadcom/files.broadcom

664a7497 - Implement a generic bhnd(4) device enumeration table API.

Sat, 03 Sep 2016 23:57:17 +0000

Implement a generic bhnd(4) device enumeration table API.This defines a new bhnd_erom_if API, providing a common interface to deviceenumeration on siba(4) and bcma(4) devices, for use both in the bhndb bridgeand SoC early boot contexts, and migrates mips/broadcom over to the new API.This also replaces the previous adhoc device enumeration support implementedfor mips/broadcom.Migration of bhndb to the new API will be implemented in a follow-up commit.- Defined new bhnd_erom_if interface for bhnd(4) device enumeration, along with bcma(4) and siba(4)-specific implementations.- Fixed a minor bug in bhndb that logged an error when we attempted to map the full siba(4) bus space (18000000-17FFFFFF) in the siba EROM parser.- Reverted use of the resource's start address as the ChipCommon enum_addr in bhnd_read_chipid(). When called from bhndb, this address is found within the host address space, resulting in an invalid bridged enum_addr.- Added support for falling back on standard bus_activate_resource() in bhnd_bus_generic_activate_resource(), enabling allocation of the bhnd_erom's bhnd_resource directly from a nexus-attached bhnd(4) device.- Removed BHND_BUS_GET_CORE_TABLE(); it has been replaced by the erom API.- Added support for statically initializing bhnd_erom instances, for use prior to malloc availability. The statically allocated buffer size is verified both at runtime, and via a compile-time assertion (see BHND_EROM_STATIC_BYTES).- bhnd_erom classes are registered within a module via a linker set, allowing mips/broadcom to probe available EROM parser instances without creating a strong reference to bcma/siba-specific symbols.- Migrated mips/broadcom to bhnd_erom_if, replacing the previous MIPS-specific device enumeration implementation.Approved by: adrian (mentor)Differential Revision: https://reviews.freebsd.org/D7748 List of files: /freebsd-12.1/sys/mips/broadcom/files.broadcom
