Thanks for the review. There are some bug fix patches that need to go in first before I push these patches upstream. I will post the bug fix patches after India team has done their testing. Amitay.
This patchset adds support for POWER10 (P10) processor to libpdbg. Starting from P10, most of the hardware accesses from BMC go via sbe. This is implemented as a seperate sbefifo backend. On a secure P10 system, raw devices used by kernel driver will not work and all hardware access (except fsi) must go via SBE. SBEFIFO library is updated to deal with slightly different conventions between P9 and P10 when specifying core ids. New chip-ops are added to SBE to read scoms from ocmb. v2 changes: - Add missing static declarations for p10 hardware units - Split p10 address translation tests patch - Drop IBM confidential prolog from imported EKB code - Document source of libsbefifo api specification Alistair Popple (3): libpdbg: Introduce p10 FAPI targets and address translation dts: Add p10 targets to device tree tests: Add fapi p10 address translation tests Amitay Isaacs (17): libpdbg: Add p10 dts: Add p10 device tree libpdbg: Enable p10 BMC backend tests: Import P10 SCOM HWP for address translation tests tests: Add P10 address translation tests wrapper libpdbg: Add processor type to libsbefifo implementation libsbefifo: Add implementation of suspend_io chipop libsbefifo: Add new definitions for P10 sbe libsbefifo: P10 dropped put_ring_from_image chipop libpdbg: Update sbefifo chip-ops as per changes in p10 libsbefifo: Use proper cast libsbefifo: Update sram get/put api libsbefifo: Add new chip-ops for hw register get/put libpdbg: Add ocmb hwunit libpdbg: Add sbefifo based implementation of ocmb getscom/putscom libpdbg: Add ocmb_{getscom/putscom} api dts: Add ocmb targets to p10.dts Makefile.am | 16 +- libpdbg/cfam.c | 2 + libpdbg/cronus.c | 18 +- libpdbg/dtb.c | 45 +- libpdbg/hwunit.h | 22 + libpdbg/libpdbg.h | 23 + libpdbg/ocmb.c | 85 ++ libpdbg/p10_fapi_targets.c | 583 +++++++++++ libpdbg/p10_scom_addr.h | 133 +++ libpdbg/sbefifo.c | 87 +- libpdbg/target.c | 38 + libpdbg/target.h | 3 +- libsbefifo/cmd_control.c | 53 +- libsbefifo/cmd_memory.c | 75 +- libsbefifo/cmd_register.c | 131 +++ libsbefifo/cmd_ring.c | 3 + libsbefifo/cmd_scom.c | 6 +- libsbefifo/connect.c | 26 +- libsbefifo/libsbefifo.h | 67 +- libsbefifo/sbefifo_private.h | 8 +- p10.dts.m4 | 622 ++++++++++++ src/tests/libpdbg_p10_fapi_translation_test.C | 113 +++ src/tests/p10_cu.H | 102 ++ src/tests/p10_scom_addr.C | 916 ++++++++++++++++++ src/tests/p10_scom_addr.H | 700 +++++++++++++ src/tests/p10_scominfo.C | 838 ++++++++++++++++ src/tests/p10_scominfo.H | 89 ++ tests/test_p10_fapi_translation.sh | 206 ++++ 28 files changed, 4936 insertions(+), 74 deletions(-) create mode 100644 libpdbg/ocmb.c create mode 100644 libpdbg/p10_fapi_targets.c create mode 100644 libpdbg/p10_scom_addr.h create mode 100644 p10.dts.m4 create mode 100644 src/tests/libpdbg_p10_fapi_translation_test.C create mode 100644 src/tests/p10_cu.H create mode 100644 src/tests/p10_scom_addr.C create mode 100644 src/tests/p10_scom_addr.H create mode 100644 src/tests/p10_scominfo.C create mode 100644 src/tests/p10_scominfo.H create mode 100755 tests/test_p10_fapi_translation.sh
