Scott Johnson	6cfe0efabc	Merge pull request #1132 from YenHaoChen/pr-commit_log_print_value fix print message of width=8 accesses	4 years ago
YenHaoChen	1ed2dc3b3c	fix mevent_mask for Sscofpmf extension The mevent_mask of Sscofpmf depends on the support of privilege modes. The UINH, SINH, VSINH, and VUINH are read-only 0 if unsupporting the corresponding modes. (https://github.com/riscv/riscv-count-overflow/issues/3#issuecomment-1291247070) This commit fixes the mevent_mask of Sscofpmf accordingly. The previous MHPMEVENTH_UINH is a typo, which should be MHPMEVENT_SINH instead.	4 years ago

Jerry Zhao	cefccba8cf	Remove memif_endianness_undecided, change default to little-endian	4 years ago
YenHaoChen	9120e98589	fix print message of size-1 accesses The number of digits indicates the size of accesses. A size-1 access needs two digits instead of one.	4 years ago
Andrew Waterman	5a50590f25	Merge pull request #1122 from riscv-software-src/more-mmu-simplification Fix minor MMU bugs; clean up MMU some more	4 years ago
Andrew Waterman	9cf4e82ec2	Merge pull request #1125 from riscv-software-src/cbo-fixes Fix tval reporting for CBOs; constrain cache-block sizes to reasonable values	4 years ago
Andrew Waterman	c10ad3c85a	Use reg_t, not uint64_t, for address-like quantities	4 years ago
Andrew Waterman	6b689208d9	Fix tval reporting for CBOs mmu_t::translate may raise exceptions and so must be called with the original virtual address for tval to be set correctly.	4 years ago
Andrew Waterman	da21648472	Set 16..4096-byte bound on cache-block size 16 B suffices to subsume all aligned accesses (including the Q extension). Spike does not actually rely on this property, but in some real systems, it is impractical to guarantee atomicity across cache lines. 4096 B suffices to prevent cache lines from spanning pages (which would require multiple TLB accesses). This one is a bug fix, since we were not performing multiple TLB accesses in this case.	4 years ago
YenHaoChen	e8340aedc8	move fucntion cto() from processor.h to arith.h Only triggers.cc uses the arithmetic function cto(). Instead of putting the cto() in processor.h, putting it in arith.h with other arithmetic functions, e.g., ctz() and clz(), makes more sense.	4 years ago

Andrew Waterman	7b52a249c8	DRY in store-conditional instructions	4 years ago
Andrew Waterman	635985515f	Simplify check_load_reservation Invoking refill_tlb to get the physical address is somewhat baroque, and not even helpful in practice, since successful SCs will fill the TLB anyway.	4 years ago
Andrew Waterman	5cdb39484c	Template-ize hypervisor loads and stores	4 years ago
Andrew Waterman	a09b88d4ab	Remove require_alignment flag from loads The last remaining use was LR, which we can identify through other means.	4 years ago
Andrew Waterman	905db657f5	Fix imprecise exception on LR to MMIO space The old implementation performed the load before checking whether the memory region was valid for LR. So, for LR to MMIO, we would action side effects before raising the exception, which is not precise.	4 years ago
Andrew Waterman	5746722334	Template-ize load_func macro For now, preserve the macro for compatibility with existing uses.	4 years ago
Andrew Waterman	15bad75ecc	Template-ize store_func macro For now, preserve the macro for compatibility with existing uses.	4 years ago
Andrew Waterman	1caaaa5471	No need to require_alignment for the load part of the AMO The earlier call to store_slow_path will catch the misalignment.	4 years ago
Andrew Waterman	24907dfbd1	Remove actually_store and require_alignment parameters from store_func macro These are now only used by AMOs. Since AMOs are relatively uncommon, and since the slow path really isn't slow anymore, send them down the slow path to simplify the common case.	4 years ago

Weiwei Li	2b7edec863	do memcpy only for actually_store in store_slow_path_intrapage	4 years ago
