2014-03-11qapi script: support enum type as discriminator in unionWenchao Xia
By default, any union will automatically generate a enum type as "[UnionName]Kind" in C code, and it is duplicated when the discriminator is specified as a pre-defined enum type in schema.

2014-03-11qapi script: check correctness of unionWenchao Xia
Since line info is remembered as QAPISchema.line now, this patch uses it as additional info for every expr in QAPISchema inside qapi.py, then improves error message with it in checking of exprs. For common union the patch will check whether base is a valid complex type if specified. For flat union it will check whether base presents, whether discriminator is found in base, whether the key of every branch is correct when discriminator is an enum type.

2014-03-11pc: avoid duplicate names for ROM MRsMichael S. Tsirkin
Since commit 04920fc0faa4760f9c4fc0e73b992b768099be70 loader: store FW CFG ROM files in RAM RAM MRs including ROM files in FW CFGs are created and named using the file basename. This becomes problematic if these names are supplied by user, since the basename might not be unique. There are two cases we care about: - option-rom flag. - option ROM for devices. This triggers e.g. when using rombar=0. At the moment we get an assert. E.g qemu -option-rom /usr/share/ipxe/8086100e.rom -option-rom /usr/share/ipxe.efi/8086100e.rom RAMBlock "/rom@genroms/8086100e.rom" already registered, abort! This is a regression from 1.6. For now let's keep it simple and just avoid creating the MRs in case of option ROMs. when using 1.7 machine types, enable option ROMs in RAM to match that version. Signed-off-by: Michael S.

2014-03-10target-arm: Fix incorrect setting of E bit in CPSRPeter Maydell
Commit 4cc35614a moved the exception mask bits out of env->uncached_cpsr and into env->daif. However the env->daif contents are AArch64 style mask bits, which include not just the AArch32 AIF bits but also the new D bit (masks debug exceptions). This means that when reconstructing the AArch32 CPSR value we must not allow the D bit in env->daif to get into the CPSR, because the corresponding bit in the CPSR is E, the endianness bit. This bug didn't affect execution under TCG because we don't implement endianness-swapping and so simply ignored the E bit; however it meant that kernel booting under KVM failed, because KVM does honour the E bit.

2014-03-10ui/vnc: optimize dirty bitmap trackingPeter Lieven
vnc_update_client currently scans the dirty bitmap of each client bitwise which is a very costly operation if only few bits are dirty. vnc_refresh_server_surface does almost the same. this patch optimizes both by utilizing the heavily optimized function find_next_bit to find the offset of the next dirty bit in the dirty bitmaps. The following artifical test (just the bitmap operation part) running vnc_update_client 65536 times on a 2560x2048 surface illustrates the performance difference: All bits clean - vnc_update_client_new: 0.07 secs vnc_update_client_old: 10.98 secs All bits dirty - vnc_update_client_new: 11.26 secs vnc_update_client_old: 20.19 secs Few bits dirty - vnc_update_client_new: 0.08 secs vnc_update_client_old: 10.98 secs The case for all bits dirty is still rather slow, this is due to the implementation of find_and_clear_dirty_height.
