2011-10-04qapi: convert query-nameAnthony Liguori
A simple example conversion 'info name'. This also adds the new files for QMP and HMP. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-10-04qapi: Automatically generate a _MAX value for enumsLuiz Capitulino
It's the last value in the enum and is very useful for the C implementation. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-10-04qapi: Don't use c_var() on enum stringsLuiz Capitulino
Otherwise if we have something like 'foo-bar' in the schema, it will be generated as 'foo_bar' in the string lookup table. c_var() is good for C variables, but not for enum strings. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2011-10-04qapi: modify visitor code generation for list iterationMichael Roth
Modify logic such that we never assign values to the list head argument to progress through the list on subsequent iterations, instead rely only on having our return value passed back in as an argument on the next call. Also update QMP I/O visitors and test cases accordingly, and add a missing test case for QmpOutputVisitor.

2011-10-04qapi: dealloc visitor, support freeing of nested listsMichael Roth
Previously our logic for keeping track of when we're visiting the head of a list was done via a global bool. This can be overwritten if dealing with nested lists, so use stack entries to track this instead.

2011-10-04qapi: dealloc visitor, fix premature free and iteration logicMichael Roth
Currently we do 3 things wrong: 1) The list iterator, in practice, is used in a manner where the pointer we pass in is the same as the pointer we assign the output to from visit_next_list(). This causes an infinite loop where we keep freeing the same structures. 2) We attempt to free list->value rather than list. visit_type_<type> handles this. We should only be concerned with the containing list. 3) We free prematurely: iterator function will continue accessing values we've already freed. This patch should fix all of these issues. QmpOutputVisitor also suffers from 1).

2011-10-04qapi: add code generation support for middle modeAnthony Liguori
To get the ball rolling merging QAPI, this patch introduces a "middle mode" to the code generator. In middle mode, the code generator generates marshalling functions that are compatible with the current QMP server. We absolutely need to replace the current QMP server in order to support proper asynchronous commands but using a middle mode provides a middle-ground that lets us start converting commands in tree. Note that all of the commands have been converted already in my glib branch. Middle mode only exists until we finish merging them from my branch into the main tree.

2011-10-04qerror: add qerror_report_err()Anthony Liguori
This provides a bridge between Error (new error mechanism) and QError (old error mechanism). Errors can be propagated whereas QError cannot. The minor evilness avoids layering violations. Since QError should go away RSN, it seems like a reasonable hack. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>

2011-10-01PPC: Drop initial ESCC mappingAlexander Graf
We are mapping ESCC to a static (incorrect) address on machine init. This overlaps with our vram, rendering the screen barely usable. Since openBIOS is clever enough to map ESCC to where it needs to be, we can just drop that invalid map and everyone's happy.

2011-10-01tcg-i386: Introduce limited deposit supportJan Kiszka
x86 cannot provide an optimized generic deposit implementation. But at least for a few special cases, namely for writing bits 0..7, 8..15, and 0..15, versions using only a single instruction are feasible. Introducing such limited support improves emulating 16-bit x86 code on x86, but also rarer cases where 32-bit or 64-bit code accesses bytes or words.

2011-09-28slirp: Fix packet expirationThomas Huth
The two new variables "arp_requested" and "expiration_date" in the mbuf structure have been added after the variable-sized "m_dat_" array. The variables have to be added before the m_dat_ array instead. Without this patch, the expiration_date gets clobbered by code that accesses the m_dat_ array. I experienced this problem with the code in slirp/tftp.c: The tftp_send_data() function created a new packet with the m_get() function (which fills-in a default expiration_date value). Then the TFTP code cleared the data section of the packet, which accidentially also cleared the expiration_date. This zeroed expiration_date then finally causes the packet to be discarded during if_start(), so that TFTP packets were not transmitted anymore.
