2010-01-27sparc64: reimplement tick timers v4Igor V. Kovalenko
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.

2009-08-04Sparc64: 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>
2009-07-27sparc64 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.
