2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-23sparc64-8bit-asiIgor V. Kovalenko
Sparc64 alternate space load/store helpers expect 8 bit ASI value, while wrasi implementation sign-extends ASI operand causing for example 0x80 to appear as 0xFFFFFF80. Resulting value falls out of switch in helpers and causes obscure load/store faults. - correct wrasi by masking lower 8 bits of xor result - use lower 8 bits of ASI register in helpers Signed-off-by: Igor V.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd
handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.

2009-08-04Sparc64: replace tsptr with helper routineIgor Kovalenko
tl and tsptr of members sparc64 cpu state must be changed simultaneously to keep trap state window in sync with current trap level. Currently translation of store to tl does not change tsptr, which leads to corrupt trap state on corresponding trap level. This patch removes tsptr from sparc64 cpu state and replaces all uses with call to helper routine. Changes v0->v1: - reimplemented helper routine with tcg generator - on cpu reset trap type and pstate are populated with power-on reset values, including tl=maxtl Signed-off-by: igor.v.kovalenko@gmail.com Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-07-31sparc64 flush pending conditional evaluations before exposing cpu stateIgor Kovalenko
If translation block is interrupted by e.g. mmu exception we need to compute conditional flags for inclusion into saved cpu state. Otherwise after return from trap conditional instructions would use stale psr/xcc data. Signed-off-by: igor.v.kovalenko@gmail.com -- Kind regards, Igor V. Kovalenko

2009-07-27sparc64 really implement itlb/dtlb automatic replacement writesIgor Kovalenko
- implement "used" bit in tlb translation entry - mark tlb entry used if qemu code/data translation succeeds - fold i/d mmu replacement writes code into replace_tlb_1bit_lru which adds 1bit lru replacement algorithm; previously code tried to replace first unlocked entry only - extract more bitmasks to named macros - add "immu" or "dmmu" type name to debugging output where appropriate Signed-off-by: igor.v.kovalenko@gmail.com -- Kind regards, Igor V. Kovalenko
2009-07-27sparc64 name mmu registers and general cleanupIgor Kovalenko
- add names to mmu registers, this helps understanding the code which uses/modifies them. - fold i/d mmu tlb entries tag and tte arrays into arrays of tlb entries - extract demap_tlb routine (code duplication) - extract replace_tlb routine (code duplication) - flush qemu tlb translations when replacing sparc64 mmu tlb entries I have no test case which demands flushing qemu translations, and this patch should have no other visible changes to runtime.
