2011-02-01SPARC: Fix Leon3 cache controlFabien Chouteau1-2/+6
The "leon3_cache_control_int" (op_helper.c) function is called within leon3.c which leads to segfault error with the global "env". Now cache control is a CPU feature and everything is handled in op_helper.c. Signed-off-by: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-01-24SPARC: Emulation of Leon3Fabien Chouteau1-14/+23
Leon3 is an open-source VHDL System-On-Chip, well known in space industry (more information on http://www.gaisler.com). Leon3 is made of multiple components available in the GrLib VHDL library. Three devices are implemented: uart, timers and IRQ manager. You can find code for these peripherals in the grlib_* files.

- cpu_mmu_index return MMU_NUCLEUS_IDX if trap level is not zero - cpu_get_tb_cpu_state: store trap level and primary context in flags this allows to restart code translation when address translation is changed - stop translation block after writing to pstate and tl registers - stop translation block after writing to alternate space this can be optimized to stop only if address translation can be changed by write operation (e.g. by comparing with MMU ASI values) Signed-off-by: Igor V.

2010-01-27sparc64: reimplement tick timers v4Igor V. Kovalenko1-6/+22
sparc64 timer has tick counter which can be set and read, and tick compare value used as deadline to fire timer interrupt. The timer is not used as periodic timer, instead deadline is set each time new timer interrupt is needed. v3 -> v4: - coding style v2 -> v3: - added missing timer debug output macro - CPUTimer struct and typedef moved to cpu.h - change CPU_SAVE_VERSION to 6, older save formats not supported v1 -> v2: - new conversion helpers cpu_to_timer_ticks and timer_to_cpu_ticks - save offset from clock source to implement cpu_tick_set_count - renamed struct sun4u_timer to CPUTimer - load and save cpu timers v0 -> v1: - coding style Signed-off-by: Igor V.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-1/+1
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.

2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd1-0/+1
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 Kovalenko1-1/+2
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>
2009-07-27sparc64 really implement itlb/dtlb automatic replacement writesIgor Kovalenko1-0/+11
- 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 Kovalenko1-6/+32
- 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.

2009-05-19Hardware convenience libraryPaul Brook1-2/+0
The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target. Remove and poison various target specific macros to avoid bogus target dependencies creeping back in. Big/Little endian is not handled because devices should not know or care about this to start with. Signed-off-by: Paul Brook <paul@codesourcery.com>

2008-11-18Refactor translation block CPU state handling (Jan Kiszka)aliguori1-0/+16
This patch refactors the way the CPU state is handled that is associated with a TB. The basic motivation is to move more arch specific code out of generic files. Specifically the long #ifdef clutter in tb_find_fast() has to be overcome in order to avoid duplicating it for the gdb watchpoint fixes (patch "Restore pc on watchpoint hits").
