Luke Wren af08c0becd Fix initiation of SBA reads not being masked by previous SBA error or busy error. 2024-03-17 05:49:45 +00:00
Luke Wren c11581e80b Fix use of non-always-on clock for arbitration of load/store vs SBA,
which prevents SBA accesses from making progress whilst the processor
clock is gated during sleep.

(e.g. for running tests against rvcpp or an external simulator
2023-11-04 12:16:39 +00:00
Luke Wren 2f6e98335f Add two new tests for IRQs-over-Zcmp, and fix a bug they found:
Interrupting the PC-setting step of a cm.popret (only) can sample the return target
as the exception return PC, which will cause the stack pointer adjust to be skipped
when returning from the IRQ. Fix this by making the PC-setting step uninterruptible

(note the PC-setting step is the instruction we execute first out of the group
of instructions specified in the Zc spec as being atomic wrt interrupts. This
does not itself imply that the PC-setting step is uninterruptible, it just
requires that when the PC-setting step retires, all following steps also retire.
However this is not sufficient given the special case logic that allows the jr
ra PC-setting step to execute before the final stack adjust as an optimisation.)

Luke Wren ca40c077be Capture JTAG bitbang log from most recent SMP debug test.
Regarding intermittent failure of SMP debug MemorySampleSingle test:
https://twitter.com/wren6991/status/1640153934445543426

Seems to be an OpenOCD issue, not a Hazard3 issue.

Luke Wren e89ab0d095 tb_cxxrtl: explicitly use set<bool> when there is only one timer IRQ
(i.e. single-core testbench). Avoids some odd behaviour with wide
assignment to single-bit wire from the CXXRTL harness.

Luke Wren 5aee830ac0 Restore SW Makefiles to use whatever riscv32-unknown-elf toolchain is in PATH
(clean up fallout from Zc implementation -- ensure Readme instructions will get you to hello world)
2023-03-31 01:53:28 +01:00
Luke Wren a861a110c1 Update to the latest riscv-arch-test. This uses the new test
framework -- scripts are a little janky for now.

Note there is one test failure (cebreak-01) -- analysis shows
this is due to the reference vector expecting mtval to be set
informatively, whereas our implementation (legally) ties it
to zero. Non-mtval-related signature for that test is correct
so I'm saying this is fine.

Luke Wren 97121afa91 Extend testbench to allow dumping/replaying JTAG to text file.
This allows debugging of tests that behave differently when VCD dumping
is enabled, due to the difference in execution speed.
(A couple of the SMP debug tests fail intermittently.)

Luke Wren c41fe0609b Add a second mtimecmp comparator to TB IO, for dual-core InterruptTest from RISC-V debug tests.
