* Include hw/hw.h exactly where neededMarkus Armbruster2019-08-161-1/+0Star
| | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

* hw/display/framebuffer.c: Avoid overflow for framebuffers > 4GBPeter Maydell2017-01-241-1/+1
| | | | | | | | | | Coverity points out that calculating src_len by multiplying src_width by rows could overflow. This can only happen in the implausible case of a framebuffer larger than 4GB, but we may as well fix it, placating Coverity.

* hw/display: Clean up includesPeter Maydell2016-01-291-0/+1

* framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebufferPaolo Bonzini2015-07-241-34/+41
| | | | | | | | | | | | | | | | | | The MemoryRegionSection contains enough information to access the RAM region underlying the framebuffer, and can be cached inside the display device. By doing this, the new framebuffer_update_memory_section function can enable dirty memory logging on the relevant RAM region. The function must be called whenever the stride or base of the framebuffer changes; a simple way to cover these cases is to call it on every full frame invalidation, which is a rare case. framebuffer_update_display now works entirely on a MemoryRegionSection, without going through cpu_physical_memory_map/unmap.

* framebuffer: check memory_region_is_loggingPaolo Bonzini2015-06-051-0/+4
| | | | | | | | | | | | | | framebuffer.c expects DIRTY_MEMORY_VGA logging to be always on, but that will not be the case soon. Because framebuffer.c computes the memory region on the fly for every update (with memory_region_find), it cannot enable/disable logging by itself. Instead, always treat updates as invalidations if dirty logging is not enabled, assuming that the board will enable logging on the RAM region that includes the framebuffer.

* memory: add ref/unref callsPaolo Bonzini2013-07-041-5/+7
| | | | | | | | | | | | | | | | | Add ref/unref calls at the following places: - places where memory regions are stashed by a listener and used outside the BQL (including in Xen or KVM). - memory_region_find callsites - creation of aliases and containers (only the aliased/contained region gets a reference to avoid loops) - around calls to del_subregion/add_subregion, where the region could disappear after the first call Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* memory: make section size a 128-bit integerPaolo Bonzini2013-06-201-1/+2
| | | | | | | | | | | So far, the size of all regions passed to listeners could fit in 64 bits, because artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes An IOMMU however cannot be eliminated by the memory core, and may have an artificial size, hence we may need 65 bits to represent its size.
