2015-04-03Make PK compile on RV32Andrew Waterman5-429/+498
Of course, it doesn't work, because there's no support for fromhost/tohost devices in RV32.

2015-01-20Support linkat, unlinkat, mkdirat syscallsAndrew Waterman6-85/+100
Also, old-style syscalls e.g. open are now implemented with e.g. openat.
2015-01-20Increased max number of files,fds statically supported by pk.Christopher Celio1-2/+2
The SPECINT benchmark 445.gobmk reads in a lot of files and would sometimes fail due to being unable to open more files.

2014-12-11README: use gnu-toolchain for configure stepArun Thomas1-1/+1
2014-12-11Relocate binaries that conflict with the pk's address spaceAndrew Waterman3-19/+13
Of course, this is only possible for PIEs, e.g. the dynamic linker.

2014-10-31Implement draft of new calling conventionAndrew Waterman5-14/+12
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

* Update generated encoding.h (generated from riscv-opcodes)
2014-09-11Don't assume null pointers can't be dereferencedAndrew Waterman2-2/+2
This option breaks vm_init's access to word 0 to obtain the memory capacity.

2014-06-25Let timer interrupt stay set on pk start (IP[7]).Christopher Celio1-3/+0
Otherwise, the HW will trip the timer interrupt 4B cycles later and thus not match spike.
2014-06-13Changes to allow spike & RTL behavior to better match each other.Christopher Celio4-3/+10
- EI turned off on sys_exit. - IM/IP cleared on start. - badvaddr only saved to tf on page faults.
2014-06-12Handle options before vm_init is calledAndrew Waterman1-15/+29
This prevents ptbr etc. from being accessed when -p is passed.
