2010-02-09kvm: move kvm to use memory notifiersMichael S. Tsirkin
remove direct kvm calls from exec.c, make kvm use memory notifiers framework instead. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09kvm: move kvm_set_phys_mem aroundMichael S. Tsirkin
move kvm_set_phys_mem so that it will be later available earlier in the file. needed for next patch using memory notifiers. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-09qemu: memory notifiersMichael S. Tsirkin
This adds notifiers for phys memory changes: a set of callbacks that vhost can register and update kernel accordingly. Down the road, kvm code can be switched to use these as well, instead of calling kvm code directly from exec.c as is done now. Signed-off-by: Michael S.

2010-02-09tcg/mips: fix crash in tcg_out_qemu_ld()Aurelien Jarno
The address register is overriden when it corresponds to v0 and the fast path is taken, which leads to a crash. Fix that by using the a0 register instead. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: separate execute and read/write permissionsAurelien Jarno
On SH4, the ITLB and UTLB configurations are memory mapped, so loading ITLB entries from UTLB has to be simulated correctly. For that the QEMU TLB has to be handle the execute (ITLB) and read/write permissions (UTLB) seperately. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: fix store queue addressesAurelien Jarno
The store queues are located from 0xe0000000 to 0xe3ffffff. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-02-09target-sh4: MMU: reduce the size of a TLB entryAurelien Jarno
Reduce the size of the TLB entry from 32 to 16 bytes, reorganising members and using a bit field. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: optimize UTLB accessesAurelien Jarno
With the current code, the QEMU TLB is setup to match the read/write mode of the MMU fault. This means when read access is done, the page is setup in read-only mode. When the page is later accessed in write mode, an MMU fault happened, and the page is switch in write-only mode. This flip-flop causes a lot of calls to the MMU code and slow down the emulation. This patch changes the MMU emulation, so that the QEMU TLB is setup to match the UTLB protection key. This impressively increase the speed of the emulation.

2010-02-09target-sh4: MMU: fix ITLB priviledge checkAurelien Jarno
There is an ITLB access violation if SR_MD=0 (user mode) while the high bit of the protection key is 0 (priviledge mode). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: simplify call to tlb_set_page()Aurelien Jarno
tlb_set_page() doesn't need addresses with offset, but simply the page aligned addresses. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09target-sh4: MMU: fix mem_idx computationAurelien Jarno
The mem_idx is wrongly computed. As written in target-sh4/cpu.h, mode 0 corresponds to kernel mode (SR_MD = 1), while mode 1 corresponds to user mode (SR_MD = 0). Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-09sh7750: handle MMUCR TI bitAurelien Jarno
When the MMUCR TI bit is set, all the UTLB and ITLB entries should be flushed. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-02-06arm host: fix compiler warningStefan Weil
Compilation for arm (native or cross) results in this warning: fpu/softfloat-native.c: In function ‘float64_round_to_int’: fpu/softfloat-native.c:387: error: control reaches end of non-void function float64_round_to_int uses special assembler code for arm and has no explicit return value. As there is no obvious reason why arm should need special code, all fpu related conditionals were removed. The remaining code is standard (C99) and compiles for arm, too.

2010-02-06tcg-i386: Implement small forward branches.Richard Henderson
There are places, like brcond2, where we know that the destination of a forward branch will be within 127 bytes. Add the R_386_PC8 relocation type to support this. Add a flag to tcg_out_jxx and tcg_out_brcond* to enable it. Set the flag in the brcond2 label_next branches; pass along the input flag otherwise.

2010-02-06Add -static earlier to LDFLAGS for compile_prog()Loïc Minier
Add -static to LDFLAGS earlier as to run the compile_prog() tests with this flags, this will avoid turning on features for which a shared library is available but not a static one. Signed-off-by: Loïc Minier <lool@dooz.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-06Fix missing symbols in .rel/.rela.plt sectionsLoïc Minier
Fix .rel.plt sections in the output to not only include .rel.plt sections from the input but also the .rel.iplt sections and to define the hidden symbols __rel_iplt_start and __rel_iplt_end around .rel.iplt as otherwise we get undefined references to these when linking statically to a multilib libc.a. This fixes the static build under i386. Apply similar logic to rela.plt/.iplt and __rela_iplt/_plt_start/_end to fix the static build under amd64.

2010-02-06configure: fix compilation on hosts without -fstack-protector-allAurelien Jarno
Commit a0f291fc101a7ab3e40850a329da2cc2f2cd1f2d has enabled -fstack-protector-all on all targets, as the configure test is bogus. GCC only emits a warning and not an error if this option is not supported, so the configure scripts doesn't detect the problem. This patch changes the configure script to try the various flags with -Werror in addition to catch the possible warnings. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
