2010-01-03sparc64: switch to MMU global registers in more MMU related trapsIgor V. Kovalenko
- extended range of MMU related traps which use MMU global registers, as listed in Ultrasparc-IIi document - no visible changes, since emulation do not cause added traps Signed-off-by: Igor V. Kovalenko <igor.v.kovalenko@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-01-03target-i386: Fix "call im" on x86_64 when executing 32-bit codeAurelien Jarno
Similarly to what is done in 32938e127f50a40844a0fb9c5abb8691aeeccf7e for "jmp im", trunc the immediate to 32-bit when not running in 64-bit mode. Reported-by: Kevin O'Connor <kevin@koconnor.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-01-03loader: don't call realloc(non_null, 0) when no symbols are presentAurelien Jarno
According to C99, realloc(non_null, 0) != free(non_null), that's why it is forbidden in QEMU. When there are no symbols, nsyms equals to 0. Free the syms structure and set it to NULL instead of reallocating it with a size of 0. This fixes -kernel with stripped kernels.

2009-12-24MAC DBDMA: store register values in native endiannessAurelien Jarno

2009-12-21PPC: Make DCR uint32_tAlexander Graf
For what I know DCR is always 32 bits wide, so we should also use uint32_t to pass it along the stacks.

2009-12-21PPC64: Fix alternate timebaseAurelien Jarno
Fix the alternate time base the same way as the default timebase. SPR_ATBL should return a 64-bit value on 64 bit implementations. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-21PPC64: Fix timebaseAlexander Graf
On PPC we have a 64-bit time base. Usually (PPC32) this is accessed using two separate 32 bit SPR accesses to SPR_TBU and SPR_TBL. On PPC64 the SPR_TBL register acts as 64 bit though, so we get the full 64 bits as return value. If we only take the lower ones, fine. But Linux wants to see all 64 bits or it breaks. This patch makes PPC64 Linux work even after TB crossed the 32-bit boundary, which usually happened a few seconds after bootup.
