2010-03-12Remove cpu_get_phys_page_debug from userspace emulationPaul Brook1-7/+1
cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-01-31sparc32 don't mark page dirty when failingArtyom Tarasenko1-5/+6
if the access check fails, the page can not be modified and shouldn't be marked dirty. The patch fixes the "hsfs_putpage: dirty HSFS page" error in Solaris guests. Signed-off-by: Artyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-01-17Sparc: improve CPU register dumpBlue Swirl1-30/+55
Common: * Remove unnecessary 0x prefix * Print %y * Fix NZVC flag print order to match CPU bit order Sparc64 specific: * Print registers without line wrapping * Print %f40-%f63 * Pretty print CCR flags * Print %fsr and %fprs in full precision * More consistent formatting Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-18/+18
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.

2009-08-04Sparc64: replace tsptr with helper routineIgor Kovalenko1-2/+3
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 Kovalenko1-1/+3
- 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 Kovalenko1-28/+40
- 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.
