2012-04-15w64: Fix time conversion for some versions of MinGW-w64Stefan Weil
tb.time is a time value, but not necessarily of the same size as time_t: while time_t is 64 bit for w64, tb.time still is 32 bit only. Therefore we need en explicit conversion. Signed-off-by: Stefan Weil <sw@weilnetz.de>

2012-04-15w64: Fix type cast in os_host_main_loop_waitStefan Weil
Casting a pointer to an integer must use (DWORD_PTR) instead of (DWORD). This also matches the definition of 'fd' (gint for w32, gint64 for w64). Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Fix data types in softmmu*.hStefan Weil
w64 requires uintptr_t. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Use uintptr_t in exec.cStefan Weil
Replace all type casts to 'long' or 'unsigned long' by 'intptr_t' or 'uintptr_t'. For type casts which are only used to extract the lower bits of an address or to modify those bits, signedness does not matter. There I always use 'uintptr_t'. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15softmmu: Use uintptr_t for physaddr and rename itStefan Weil
Variable physaddr is a host address which should be represented by data type 'uintptr_t'. This is needed for w64 and changes nothing for other hosts. v2: Rename physaddr -> hostaddr (suggested by Blue Swirl). Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Fix struct CPUTLBEntryStefan Weil
For w64, some entries need 'uintptr_t' instead of 'unsigned long'. For other host systems, both data types are identical, so nothing changes. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Fix definition of setjmpStefan Weil
The default definition of setjmp which is implemented in MinGW-w64 cannot be used with programs like QEMU which call longjmp from code without structured exception handling (SEH). This code therefore disables stack unwinding. We could also implement SEH for QEMU's generated JIT code, but that is much more difficult. Stack unwinding would also cost execution time. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w32: Move defines for socket specific errors to qemu-os-win32.hStefan Weil
As those defines are only used for w32, they should be in the header file for w32. All files which include slirp.h or qemu_socket.h also include qemu-os-win32.h. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Use larger alignment for section with generated codeStefan Weil
The MinGW-w64 compiler allows __attribute__((aligned (32)). Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Fix data types in cpu-all.h, exec.cStefan Weil
w64 needs uintptr_t instead of unsigned long. For other hosts, nothing changes. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Fix type casts used in some macros in cpu-all.hStefan Weil
Instead of type casts to long, w64 needs type casts to intptr_t. For other hosts, this changes nothing. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15tcg/i386: Add support for w64 ABIStefan Weil
w64 uses the registers rcx, rdx, r8 and r9 for function arguments, so it needs a different declaration of tcg_target_call_iarg_regs. rax, rcx, rdx, r8, r9, r10 and r11 may be changed by function calls. rbx, rbp, rdi, rsi, r12, r13, r14 and r15 remain unchanged by function calls.

2012-04-15tcg/i386: Use GDB JIT debugging interface only for hosts with ELFStefan Weil
Not all i386 / x86_64 hosts use ELF. Ask the compiler whether ELF is used. On w64, gdb crashes when ELF_HOST_MACHINE is defined. Cc: Blue Swirl <blauwirbel@gmail.com> Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Stefan Weil <sw@weilnetz.de>

2012-04-15pseries: Fix reset of VIO network deviceDavid Gibson
Currently, the PAPR VIO network device does not have a reset handler. This means that after a hard reset, H_REGISTER_LOGICAL_LAN will return an error when the new guest boot attempts to initialize the device. This patch corrects this, adding a suitable reset hook.

2012-04-15pseries: Correctly use the device model reset hooksDavid Gibson
Recently we added code to properly clean away VIO CRQs on reset However, this directly uses qemu_register, rather than the existing device model reset callbacks. This patch cleans this up by adding proper use of the reset hook to the VIO bus model. The existing CRQ reset code is converted to the new method.

2012-04-15pseries: Remove old hcalls hook stubDavid Gibson
Some time ago we removed all use of the 'hcalls' callback in the pseries VIO code, which was used to workaround an ordering problem which has since been solved properly. However, the function pointer for the hook remains. This patch cleans it away. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Andreas Färber <afaerber@suse.de>

2012-04-15pseries: Fix RTAS based config accessDavid Gibson
On the pseries platform, access to PCI config space is via RTAS calls( which go to the hypervisor) rather than MMIO. This means we don't use the same code path as nearly everyone else which goes through pci_host.c and we're missing some of the parameter checking along the way. We do have some parameter checking in the RTAS calls, but it's not enough. It checks for overruns, but does not check for unaligned accesses, oversized accesses (which means the guest could trigger an assertion failure from pci_host_config_{read,write}_common(). Worse it doesn't do the basic checking for the number of RTAS arguments and results before accessing them. This patch fixes these bugs. Cc: Michael S.

2012-04-15target-ppc: Add hooks for handling tcg and kvm limitationsDavid Gibson
On target-ppc, our table of CPU types and features encodes the features as found on the hardware, regardless of whether these features are actually usable under TCG or KVM. We already have cases where the information from the cpu table must be fixed up to account for limitations in the emulation method we're using. e.g. TCG does not support the DFP and VSX instructions and KVM needs different numbering of the CPUs in order to tell it the correct thread to core mappings. This patch cleans up these hacks to handle emulation limitations by consolidating them into a pair of functions specifically for the purpose.

2012-04-15pseries: Consolidate hack for RTAS display-character usageDavid Gibson
Currently the pseries machine contains not one but two somewhat ugly hacks to allow printing of early debug messages before the guest has properly read the device tree. First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually invalid) will look for a suitable vty and use that. This supports Linux's early debug code which will use H_PUT_TERM_CHAR with vtermno==0 before reading the device tree. Second, we support the RTAS display-character call. This takes no vtermno so we assume the address of the default first VTY. This patch makes things more consistent by folding the second hack into the first. Now, display-character uses the existing vty_lookup() function to do the same search for a suitable VTY.

2012-04-15pseries: Fix bug with reset of VIO CRQsDavid Gibson
PAPR specifies a Command Response Queue (CRQ) mechanism used for virtual IO, which we implement. However, we don't correctly clean up registered CRQs when we reset the system.

2012-04-15PPC: Fix TLB invalidation bug within the PPC interrupt handler.Mark Cave-Ayland
Commit 41557447d30eeb944e42069513df13585f5e6c7f also introduced a subtle TLB flush bug. By applying a mask to the interrupt MSR which cleared the IR/DR bits at the start of the interrupt handler, the logic towards the end of the handler to force a TLB flush if either one of these bits were set would never be triggered. This patch simply changes the IR/DR bit check in the TLB flush logic to use the original MSR value (albeit with some interrupt-specific bits cleared) so that the IR/DR bits are preserved at the point where the check takes place.
