2013-10-14exec: Fix prototype of phys_mem_set_alloc and related functionsStefan Weil
phys_mem_alloc and its assigned values qemu_anon_ram_alloc and legacy_s390_alloc must have identical argument lists. legacy_s390_alloc uses the size parameter to call mmap, so size_t is good enough for all of them.

2013-10-12target-alpha: Convert to new ldst opcodesRichard Henderson
Or, partially. The fundamental primitives for the port are gen_load_mem and gen_store_mem, which take a callback to emit the memory operation. For that, we continue to use the original inline functions that forward to the new ops, rather than replicate the same thing privately. That said, all free-standing calls to tcg_gen_qemu_* have been converted. The 32-bit floating-point references now use _i32 opcodes, eliminating a truncate or extension.

2013-10-12tcg-arm: Improve GUEST_BASE qemu_ld/stRichard Henderson
If we pull the code to emit the actual load/store into a subroutine, we can share the reg+reg addressing mode code between softmmu and usermode. This lets us load GUEST_BASE into a temporary register rather than attempting to add it piece-wise to the address. Which lets us use movw+movt for armv7, rather than (up to) 4 adds. Code size for pre-armv7 stays the same. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-10-12tcg-i386: Remove "cb" output restriction from qemu_st8 for i386Richard Henderson
Once we form a combined qemu_st_i32 opcode, we won't be able to have separate constraints based on size. This one is fairly easy to work around, since eax is available as a scratch register. When storing variable data, this tends to merely exchange one mov for another. E.g. -: mov %esi,%ecx ... -: mov %cl,(%edx) +: mov %esi,%eax +: mov %al,(%edx) Where we do have a regression is when storing constant data, in which we may load the constant into edi, when only ecx/ebx ought to be used. The proper way to recover this regression is to allow constants as arguments to qemu_st_i32, so that we never load the constant data into a register at all, must less the wrong register. TBD.

2013-10-12tcg-i386: Tidy softmmu routinesRichard Henderson
Pass two TCGReg to tcg_out_tlb_load, rather than idx+args. Move ldst_optimization routines just below tcg_out_tlb_load to avoid the need for forward declarations. Use TCGReg enum in preference to int where apprpriate. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-10-11Mostly revert "qemu-help: Sort devices by logical functionality"Markus Armbruster
This reverts most of commit 3d1237fb2ab4edb926c717767bb5e31d6053a7c5. The commit claims to sort the output of "-device help" "by functionality rather than alphabetical". Issues: * The output was unsorted before, not alphabetically sorted. Misleading, but harmless enough. * The commit doesn't just sort the output of "-device help" as it claims, it adds categories to each line of "-device help", and it prints devices once per category. In particular, devices without a category aren't shown anymore. Maybe such devices should not exist, but they do. Regression. * Categories are also added to the output of "info qdm". Silent change, not nice. Output remains unsorted, unlike "-device help". I'm going to reimplement the feature we actually want, without the warts. Reverting the flawed commit first should make it easier to review. However, I can't revert it completely, since DeviceClass member categories has been put to use. So leave that part in.

2013-10-11Use qemu-project.org domain nameStefan Hajnoczi
qemu.org is held by a third-party and no core community contributor has access to the DNS configuration. This leaves the website exposed to outages due to DNS issues or IP address changes. For example, if the web server IP address needs to change we cannot guarantee qemu.org will point to it! The newer qemu-project.org domain name is owned by Anthony Liguori <anthony@codemonkey.ws>. You can confirm this by querying the whois information. Also note that the #qemu IRC channel topic already references qemu-project.org. Short of having a dedicated legal entity to hold the domain name on behalf of the community, qemu-project.org seems like the safest bet. Let's replace references to qemu.org with qemu-project.org. Note that git-submodule(1) does not detect URL changes. The following commands clear out and re-initialize all submodules to ensure you are using the latest URLs: $ git submodule deinit . # you'll be warned if you have local changes $ rm -rf .git/modules # also clear cached .git/ directories $ git submodule update --init Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-id: 1381495958-8306-1-git-send-email-stefanha@redhat.com Signed-off-by: Anthony Liguori <aliguori@amazon.com>

Working on a QDict instead of a QemuOpts that accepts anything is more in line with bdrv_open(). A QDict is what qmp_blockdev_add() already has anyway, so this saves additional conversions. And last, but not least, it allows later patches to easily extract legacy options into a separate, typed QemuOpts for drive_init() (the untyped QemuOpts that drive_init already has doesn't allow access to numbers, only strings, and is therefore useless without conversion).
