2011-10-08target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson
The alarm is a fully general one-shot time comparator, which will be usable under Linux as a hrtimer source. It's much more flexible than the RTC source available on real hardware. The wall clock allows the guest access to the host timekeeping. Much like the KVM wall clock source for other guests. Both are accessed via the PALcode Cserve entry point.

2011-05-31target-alpha: Tidy exception constants.Richard Henderson
There's no need to attempt to match EXCP_* values with PALcode entry point offsets. Instead, compress all the values to make for more efficient switch statements within QEMU. We will be doing TLB fill within QEMU proper, not within the PALcode, so all of the ITB/DTB miss, double fault, and access exceptions can be compressed to EXCP_MMFAULT. Compress all of the EXCP_CALL_PAL exceptions into one. Use env->error_code to store the specific entry point. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Rationalize internal processor registers.Richard Henderson

2010-02-28alpha-linux-user: Implement signals.Richard Henderson

2010-02-23target-alpha: Reduce internal processor registers for user-mode.Richard Henderson
The existing set of IPRs is totally irrelevant to user-mode emulation. Indeed, they most are irrelevant to implementing kernel-mode emulation, and would only be relevant to PAL-mode emulation, which I suspect that no one will ever attempt. Reducing the set of processor registers reduces the size of the CPU state. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-23target-alpha: Split up FPCR value into separate fields.Richard Henderson

2009-12-13target-alpha: Fixes for alpha-linux syscalls.Richard Henderson
1. Add correct definitions of error numbers. 2. Implement SYS_osf_sigprocmask 3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL. This last requires exposing the FPCR value to do_syscall. Since this value is actually split up into the float_status, expose routines from helper.c to access it. Finally, also add a float_exception_mask field to float_status. We don't actually use it to control delivery of exceptions to the emulator yet, but simply hold the value that we placed there when loading/storing the FPCR.

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.

2009-08-24cleanup 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.

2008-11-18Refactor translation block CPU state handling (Jan Kiszka)aliguori
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").
