Author	SHA1	Message	Date
Andrew Waterman	1355e73ce2	Remove vestiges of legacy RVV SLEN parameter	5 years ago
Andrew Waterman	583bd1e8b7	Merge pull request #821 from scottj97/vector-csrs Convert vector CSRs to csr_t -- completes refactoring of CSRs	5 years ago
Scott Johnson	4245b20c36	Remove no-longer-needed csr_read_only check in validate_csr() All CSR permissions checks now occur inside the csr_t::verify_permissions() methods. This reverts commit 62526773c0.	5 years ago
Scott Johnson	12b58975e3	Modify logic for exception on writes to read-only CSRs To abide by this recent spec change: https://github.com/riscv/riscv-isa-manual/pull/694 Discussed here: 4630011984 This has no functional effect today because the validate_csr() macro in decode.h has already intercepted and thrown trap_illegal_instruction() before we reach this code. But I plan to remove that check next, now that all CSRs are converted to the csr_t system. After that, this code will matter.	5 years ago
Scott Johnson	b75861418e	Remove no-longer-needed code for CSR reads/writes All this has moved to the individual csr_t objects.	5 years ago
Scott Johnson	c73f94a4df	Correction to address of FCSR No functional effect, because composite_csr_t doesn't actually use the address for anything.	5 years ago
Scott Johnson	3feb3c7e84	Convert vcsr to csr_t	5 years ago
Scott Johnson	77362855bd	Convert vlenb to csr_t Since it's constant, no new trace events will be seen.	5 years ago
Scott Johnson	9ac2dcf9a5	Convert vtype to csr_t Adds commit log events for vtype to many vector instructions.	5 years ago
Scott Johnson	88c1bfce90	Convert vl to csr_t Adds commit log events for vl to many vector instructions.	5 years ago
Scott Johnson	464a7fb56a	Convert vxrm to csr_t	5 years ago
Scott Johnson	72a6f9fac8	Convert vstart to csr_t Adds commit log events for vstart to many vector instructions.	5 years ago

Scott Johnson	71faab7fa3	Convert sentropy to csr_t	5 years ago
Scott Johnson	3083b125d6	Fix `csrrw sentropy` when --log-commits is enabled The logging calls get_csr(write=false, peek=true) which caused an illegal instruction trap on every sentropy access. The logged value will be useless, though, since it will fetch two more bytes from /dev/urandom for the logged value reported. But it's not clear that there's a more useful option.	5 years ago
Andrew Waterman	6d9fb18850	Merge pull request #816 from scottj97/fp-csrs Convert floating-point CSRs to csr_t	5 years ago
Scott Johnson	7fecd35cda	Convert FCSR to csr_t	5 years ago
Scott Johnson	bb09cd92b2	Remove unnecessary double-setting of mstatus.FS=Dirty fflags->write() already sets that.	5 years ago
Scott Johnson	2b26a3cdf1	Convert frm & fflags to csr_t Adds proper logging of fflags on FP arithmetic ops.	5 years ago
Scott Johnson	ede97384f6	Fix logging of FCSR and VCSR It looks like `csrw fcsr` was intended to log writes to FFLAGS, FRM, and FCSR, but only logged FCSR (because LOG_CSR() always used `which` to record which CSR was written). This changes it to log writes to FRM and FFLAGS, the two registers which compose FCSR. There's no need to log FCSR since that is already covered by the other two. The logging of `csrw vcsr` was intended to log writes to VXSAT and VXRM but instead would report a write to VCSR that only showed the contents of VXRM.	5 years ago
Andrew Waterman	663f71bb86	Merge pull request #815 from scottj97/mstatush Convert mstatush to csr_t	5 years ago
Andrew Waterman	f9647e824f	Merge pull request #813 from scottj97/debug-csrs Convert debug csrs to csr_t	5 years ago
Scott Johnson	dac0d3ce71	Make mstatush bits writable on hypervisor configs Fixes #812. Note that only GVA & MPV are actually writable; MBE and SBE are fixed inside mstatus_csr_t::unlogged_write().	5 years ago
Scott Johnson	0088ece83a	Convert mstatush to csr_t Maintains non-writability reported as issue #812	5 years ago
Scott Johnson	4730be82e6	Allow `csrr mstatush` to see MPV and GVA bits too But it doesn't help much, because `csrw mstatush` doesn't do anything.	5 years ago
