Add HVX contexts to Hexagon translation, necessary for system emulation. Change the HVX instruction translation to access the context via a base pointer.
Modeling the HVX context mapping while avoiding the need to copy the context when the OS scheduler decides to remap them required some general TCG gvec changes to enable some more _var forms. In v3: - fixed HVX context alignment declarations - created hex_hvx_ptr global for sysemu, abstraction hex_hvx() to refer to the context. - added some test cases (reset Marco's R-b) In v2: - Removed unused default hvx context from target/hexagon/cpu.[ch], add a hexagon_hvx_select_context() to the reset instead. - combined the HVX pointer, QOM context, and SSR:XA selection work commits into `share HVX contexts among CPUs`. v2: https://lore.kernel.org/qemu-devel/[email protected]/ v1: https://lore.kernel.org/qemu-devel/[email protected]/ Brian Cain (6): tcg: split out _var forms of gvec logical, abs and min/max ops tcg: add base arguments to the gvec 2s, dup_i32 and cmp expanders tcg: split out _var forms of gvec saturating/mul/shift-immediate ops target/hexagon: raise an exception for HVX with SSR:XE clear target/hexagon: share HVX contexts among CPUs tests/functional/hexagon: add HVX tests include/hw/hexagon/hexagon.h | 1 + include/hw/hexagon/hexagon_hvx_context.h | 27 + include/tcg/tcg-op-gvec-common.h | 97 +++ target/hexagon/cpu.h | 28 +- target/hexagon/cpu_helper.h | 1 + target/hexagon/gen_tcg_hvx.h | 608 ++++++++++--------- target/hexagon/genptr.h | 8 + target/hexagon/mmvec/macros.h | 14 +- target/hexagon/translate.h | 14 +- hw/hexagon/hex-subsys.c | 36 ++ hw/hexagon/hexagon_hvx_context.c | 84 +++ linux-user/main.c | 3 + target/hexagon/cpu.c | 32 +- target/hexagon/cpu_helper.c | 72 +++ target/hexagon/gdbstub.c | 16 +- target/hexagon/genptr.c | 102 ++-- target/hexagon/machine.c | 12 + target/hexagon/op_helper.c | 37 +- target/hexagon/translate.c | 71 ++- tcg/tcg-op-gvec.c | 617 ++++++++++++++------ hw/hexagon/meson.build | 1 + target/hexagon/hex_common.py | 179 +++--- tests/functional/hexagon/test_arch_tests.py | 7 + tests/functional/hexagon/test_systests.py | 6 + 24 files changed, 1451 insertions(+), 622 deletions(-) create mode 100644 include/hw/hexagon/hexagon_hvx_context.h create mode 100644 hw/hexagon/hexagon_hvx_context.c -- 2.34.1
