2021-05-07pk: make breakpoints fatalAndrew Waterman1-2/+1
Resolves #216
2021-03-29pk: remove vestigial trapframe_t::insn fieldAndrew Waterman1-7/+0
This assumes that stval is populated with the opcode on illegal instruction exceptions. But since we're only using the opcode for error reporting, it's OK if this assumption is violated.
2021-03-25pk: support >2 GiB of user memory for RV64Andrew Waterman1-1/+3
Previously, the pk would always run from virtual address MEM_START. Instead, remap it into the negative virtual addresses, allowing user processes to expand beyond MEM_START.
2018-08-06Add some exception handling functions to s-mode to handle exception return ↵wxjstz1-0/+28
from m-mode. (#117)
2017-03-27Separate page faults from physical memory access exceptionsAndrew Waterman1-3/+3
2016-07-12Remove uarch countersAndrew Waterman1-7/+0
We'll re-add support for the generic performance counter facility once it exists.
2016-04-06Don't assume existence of uarch countersAndrew Waterman1-0/+7
2016-03-09Refactor pk, bbl, machine into separate librariesAndrew Waterman1-4/+4
Yuck.

2015-02-09work in progress on new supervisor specAndrew Waterman1-32/+4
2014-10-31Implement draft of new calling conventionAndrew Waterman1-2/+2
Here is the new syscall ABI: syscall number in a7 args in a0 - a6 return value in a0 Here is the integer register map: x0 -> x0 x1 -> ra x2 -> sp x3 -> tp x4 -> gp x5 -> t0 x6 -> t1 x7 -> t2 x8 -> s0 x9 -> s1 x10 -> a0 x11 -> a1 x12 -> a2 x13 -> a3 x14 -> a4 x15 -> a5 x16 -> a6 x17 -> a7 x18 -> s2 x19 -> s3 x20 -> s4 x21 -> s5 x22 -> s6 x23 -> s7 x24 -> s8 x25 -> s9 x26 -> s10 x27 -> s11 x28 -> t3 x29 -> t4 x30 -> t5 x31 -> t6
2014-10-26Don't rely on the C libraryAndrew Waterman1-2/+2
2014-06-13Changes to allow spike & RTL behavior to better match each other.Christopher Celio1-0/+2
- EI turned off on sys_exit. - IM/IP cleared on start. - badvaddr only saved to tf on page faults.

2013-01-25rename binary to pk; change argv handlingAndrew Waterman1-5/+0
the new fesvr approach makes argv[0] = pk, rather than user program's name

2011-11-11Synced up PK with supervisor changes/asm syntaxAndrew Waterman1-26/+4
You must upgrade to the latest compiler and ISA simulator to build and run this version of the PK.
