2009-10-21char: emit the OPENED event only when a new char connection is openedAmit Shah
The OPENED event gets sent also when qemu resets its state initially. The consumers of the event aren't interested in receiving this event on reset. Patchworks-ID: 35288 Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-21char: rename CHR_EVENT_RESET to CHR_EVENT_OPENEDAmit Shah
The char event RESET is emitted when a char device is opened. Give it a better name. Patchworks-ID: 35287 Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-21char: check for initial_reset_issued unnecessaryAmit Shah
At init, qemu_chr_reset is always called with initial_reset_issued set to 1. So checking for it to be set is not necessary. Patchworks-ID: 35286 Signed-off-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-17target-arm: replace thumb usage of cpu_T registers by proper register ↵Filip Navara
allocations The goal is eventually to get rid of all cpu_T register usage and to use just short-lived tmp/tmp2 registers. This patch converts all the places where cpu_T was used in the Thumb code and replaces it with explicit TCG register allocation.

2009-10-17target-arm: convert NEON VZIP/VUZP/VTRN helper functions to pure TCGFilip Navara
The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16 helpers used fixed registers to return values. This patch replaces that with TCG code, so T0/T1 is no longer directly used by the helper functions. Bugs in the gen_neon_unzip register load code were also fixed.

2009-10-17target-arm: use tcg_global_mem_new_i32 to allocate registersFilip Navara
Currently each read/write of ARM register involves a LD/ST TCG operation. This patch uses TCG memory-backed registers to represent the ARM register set. With memory-backed registers the LD/ST operations are transparently generated by TCG and host registers could be used to optimize the generated code.

2009-10-15qcow2: Bring synchronous read/write back to lifeKevin Wolf
When the synchronous read and write functions were dropped, they were replaced by generic emulation functions. Unfortunately, these emulation functions don't provide the same semantics as the original functions did. The original bdrv_read would mean that we read some data synchronously and that we won't be interrupted during this read. The latter assumption is no longer true with the emulation function which needs to use qemu_aio_poll and therefore allows the callback of any other concurrent AIO request to be run during the read. Which in turn means that (meta)data read earlier could have changed and be invalid now. qcow2 is not prepared to work in this way and it's just scary how many places there are where other requests could run. I'm not sure yet where exactly it breaks, but you'll see breakage with virtio on qcow2 with a backing file. Providing synchronous functions again fixes the problem for me.

2009-10-15Documentation: Highlight placeholders in suboptionsKevin Wolf
Currently, suboptions (i.e. something like file=file for -drive) are rendered as @code, so we're losing any @var highlighting in the man pages. Replace them by @option, so that you actually can see what is a placeholder and what is meant verbatim.

2009-10-15net: fix multiple NICs causing net opts process to stopMark McLoughlin
For NICs, net_init_client() returns the index into the NICInfo table. qemu_opts_foreach() interprets non-zero as an error return an stops iterating over the options. So, if you have more than one '-net nic' on the command line, subsequent '-net' options do not get processed. Fix this by making net_client_init() only return non-zero if net_init_client() returns an error.
