2013-09-12exec: Simplify the guest physical memory allocation hookMarkus Armbruster1-0/+2
Make it a generic hook rather than a KVM hook. Less code and ifdeffery. Since the only user of the hook is old S390 KVM, there's hope we can get rid of it some day.

2013-09-12exec: Reduce ifdeffery around -mem-pathMarkus Armbruster1-2/+0
Instead of spreading its ifdeffery everywhere, confine it to qemu_ram_alloc_from_ptr(). Everywhere else, simply test block->fd, which is non-negative exactly when block uses -mem-path.

2013-09-10abitypes.h: Remove incorrect ARM ABI_LLONG_ALIGNMENTPeter Maydell1-4/+0
The ARM EABI specifies that 64 bit integers should be 8 aligned; remove our incorrect setting of 4 alignment. This has no actual effect since it only set the alignment for the 'abi_ullong' and 'abi_llong' types, which are used only inside code which is MIPS-specific, but it will avoid problems later if we use the types elsewhere.

2013-09-05memory: Provide separate handling of unassigned io ports accessesJan Kiszka1-0/+4

2013-09-02exec: Reorganize the GETRA/GETPC macrosRichard Henderson2-52/+56
Always define GETRA; use __builtin_extract_return_addr, rather than having a special case for s390. Split GETPC_ADJ out of GETPC; use 2 universally, rather than having a special case for arm. Rename GETPC_LDST to GETRA_LDST to indicate that it does not contain the GETPC_ADJ value. Likewise with GETPC_EXT to GETRA_EXT. Perform the GETPC_ADJ adjustment inside helper_ret_ld/st. This will allow backends to pass along the "true" return address rather than the massaged GETPC value. In the meantime, double application of GETPC_ADJ does not hurt, since the call insn in all ISAs is at least 4 bytes long.

2013-08-29tcg-i386: Remove abort from GETPC_LDSTRichard Henderson1-5/+5
Indeed, remove it entirely and remove the is_tcg_gen_code check from GETPC_EXT. Fixes https://bugs.launchpad.net/qemu/+bug/1218098 wherein a call to a "normal" helper function performed a sequence of tail calls all the way into the memory helper functions, leading to a stack frame in which the memory helper function appeared to be called directly from tcg.

2013-08-26tcg-i386: Use new return-argument ld/st helpersRichard Henderson1-11/+2
Discontinue the jump-around-jump-to-jump scheme, trading it for a single immediate move instruction. The two extra jumps always consume 7 bytes, whereas the immediate move is either 5 or 7 bytes depending on where the code_gen_buffer gets located. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-26tcg: Tidy softmmu_template.hRichard Henderson1-183/+104
Avoid a loop in the tlb_fill path; the fill will either succeed or generate an exception. Inline the slow_ld/st function; it was a complete copy of the main helper except for the actual cross-page unaligned code, and the compiler was inlining it anyway. Add unlikely markers optimizing for the most common case of simple tlb miss. Make sure the compiler can optimize away the unaligned paths for a 1 byte access.

2013-08-26tcg: Add mmu helpers that take a return address argumentRichard Henderson2-33/+55
Allow the code that tcg generates to be less obtuse, passing in the return address directly instead of computing it in the helper.

2013-07-23linux-user: fix segmentation fault passing with h2g(x) != xAlexander Graf1-2/+6
When forwarding a segmentation fault into the guest process, we were passing the host's address directly into the guest process's signal descriptor. That obviously confused the guest process, since it didn't know what to make of the (usually 32-bit truncated) address. Passing in h2g(address) makes the guest process a lot happier. To make the code more obvious, introduce a h2g_nocheck() macro that does the same as h2g(), but allows us to convert addresses that may be outside of guest mapped range into the guest's view of address space.

2013-07-22configure: Make NPTL non-optionalPeter Maydell1-1/+1
Now all linux-user targets support building with NPTL, we can make it mandatory. This is a good idea because: * NPTL is no longer new and experimental; it is completely standard * in practice, linux-user without NPTL is nearly useless for binaries built against non-ancient glibc * it allows us to delete the rather untested code for handling the non-NPTL configuration Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the bsd-user codebase alone. This makes no change for bsd-user, since our configure test for NPTL had a "#include <linux/futex.h>" which means bsd-user would never have been compiled with CONFIG_USE_NPTL defined, and it still is not.

2013-07-04ioport: Switch dispatching to memory core layerJan Kiszka3-7/+1
The current ioport dispatcher is a complex beast, mostly due to the need to deal with old portio interface users. But we can overcome it without converting all portio users by embedding the required base address of a MemoryRegionPortio access into that data structure. That removes the need to have the additional MemoryRegionIORange structure in the loop on every access. To handle old portio memory ops, we simply install dispatching handlers for portio memory regions when registering them with the memory core. This removes the need for the old_portio field. We can drop the additional aliasing of ioport regions and also the special address space listener. cpu_in and cpu_out now simply call address_space_read/write. And we can concentrate portio handling in a single source file. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
