Andrew Waterman	584f8551e6	Fix segfault accessing menvcfg when U-mode doesn't exist The simplest fix is to create the CSRs even if they don't need to exist, and just skip adding them to the CSR map to prevent the target machine from being able to access them. It looks like there are other place we should be following this pattern: e.g. why does sstatus exist if S-mode does not exist? But that's a matter for another day. Resolves #1752	2 years ago

Chih-Min Chao	94d21c99f8	svpbmt: don't reset [mh]envcfg.pbmt to 1 The part is introducd by `ea70a93` to keep backward compatiable but the behavior is not mentioned and defined in spec.

YenHaoChen	229b159465	Fix ePMP checking on hlvx instructions The hlvx instruction must grant PMP permissions of both execution and reading. Thus, with ePMP (mseccfg.MML==1), the hlvx instructions are only permitted with pmpcfg.RWXL=0111 from M-mode.	2 years ago

YenHaoChen	ad86a5fc5c	Deprecate dcsr.halt The debug spec 1.0.0-rc3 deprecates the dcsr.halt and lets the bit become dcsr.nmip. This commit separates the halt variable from the dcsr.nmip and designates it as an internal variable for halt_on_reset (-H). Additionally, this commit removes the notifying comment about the deprecated dcsr.halt in the main loop.	2 years ago

YenHaoChen	eccb557d61	Fix require_vector_vs checking by reverting `66c4853bdc` The require_vector_vs, i.e., sstatus_csr_t::enabled(SSTATUS_VS), was expected to provide has_any_vector() check [1]. Unfortunately, a previous commit [2] made the sstatus_csr_t::enabled(SSTATUS_VS) true without any vector extension. The previous commit [2] was for P-extension, which has been removed from Spike [3]. This commit reverts the commit [2] and corrects require_vector_vs [1]. [1] `a484f6efc5` [2] `66c4853bdc` [3] https://github.com/riscv-software-src/riscv-isa-sim/pull/1660	2 years ago
