2009-12-02pci: move apb specific stuff to apb_pci.cMichael S. Tsirkin3-20/+29

2009-12-02configure: use correct cflags in compiler checksMichael S. Tsirkin1-20/+21
linux-user build on fedora 11 breaks because fallocate is broken on that system if -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 are specified, which is what QEMU uses. We do have a configure check to catch this and disable fallocate, however, it turns out that default QEMU_CFLAGS/LDFLAGS were assigned in script *after* all compiler checks: so during checks we were not running compiler with same flags that we used for build later. Fix this by moving QEMU_CFLAGS to before compiler checks, and using comple_prog when checking for fallocate. This also fixes the fact that we do some compiler checks while assigning the flags, right below a comment that says "no cc tests beyond this point". Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-12-02Makefile: Remove unneeded prerequisitesStefan Weil1-3/+1
Thanks to f527c57935e22b56952d1ed1af36070b682ecf70 (fix parallel build), these prerequisites are redundant now and can be removed. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-01msix: clear pending bit of an unused vectorMichael S. Tsirkin1-10/+17
PCI spec states: if a masked vector has its Pending bit set, and the associated underlying interrupt events are somehow satisfied (usually by software though the exact manner is function-specific), the function must clear the Pending bit, to avoid sending a spurious interrupt message later when software unmasks the vector. In our case this happens if vector becomes unused. Clear pending bit in this case. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01msix: fix reset value for enable bitMichael S. Tsirkin1-1/+2
On reset, we currently clear all bits in msix control register *except* enable bit. This is wrong: the spec says we should clear writeable bits: function mask and enable bit. Correct this. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01msix: fix mask bit state after resetMichael S. Tsirkin1-0/+11
PCI spec states that mask bit must be 1 after reset. Make it so. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01virtio: do not reset msix state on soft resetMichael S. Tsirkin1-4/+8
msix state is managed by OS, not the driver, so it's wrong to touch it on io from driver. Mark all vectors unused instead. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-01msix: add helper to unuse all msix entriesMichael S. Tsirkin2-0/+8

2009-12-01pci: move pci_data_{read, write}() declaration from pci.h to pci_host.hIsaku Yamahata4-2/+5

2009-12-01tcg: increase TCG_MAX_OP_SIZE to 192Aurelien Jarno1-3/+3

2009-12-01tcg: initial mips supportAurelien Jarno3-1/+1452
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org> A few words about design choices: * Two registers, at and t0, are reserved for TCG internal use. They are useful for bswap and 64-bit ops. * Most ops supports a constant argument with value 0, which is actually mapped to the zero register. * While the at register is available for constant loading, ops only support a limited range of constants. TCG does a better job doing the register allocation and constant loading by itself. There are plenty of registers available anyway. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

This causes ctrl+alt+u or ctrl+alt+f to not work when windows hasn't been resized first. Other graphic emulators do resize the screen on hw_invalidate. This reverts commit 0bd8246bfec1dfb2eb959f52db535572c0260f4c.

2009-11-24cpu-all.h: fix cpu_get_real_ticks on mips hostArnaud Patard1-9/+18
Fix cpu_get_real_ticks: - check should be done on __mips and not __mips_isa_rev - linux kernels >= 2.6.25 are emulating the 2 needed rdhwr functions so it's safe to use rdhwr. This is better than what's currently in but it doesn't mean it works nicely Some tests needs to be done imho Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
