2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-01hw: include hw header files with full pathsPaolo Bonzini1-2/+2
Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-11/+11
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-12-11Add endianness as io mem parameterAlexander Graf1-1/+1
As stated before, devices can be little, big or native endian. The target endianness is not of their concern, so we need to push things down a level. This patch adds a parameter to cpu_register_io_memory that allows a device to choose its endianness. For now, all devices simply choose native endian, because that's the same behavior as before.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-11/+11
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2008-10-31Make DMA bottom-half driven (v2)aliguori1-6/+12
The current DMA routines are driven by a call in main_loop_wait() after every select. This patch converts the DMA code to be driven by a constantly rescheduled bottom half. The advantage of using a scheduled bottom half is that we can stop scheduling the bottom half when there no DMA channels are runnable. This means we can potentially detect this case and sleep longer in the main loop. The only two architectures implementing DMA_run() are cris and i386. For cris, I converted it to a simple repeating bottom half. I've only compile tested this as cris does not seem to work on a 64-bit host. It should be functionally identical to the previous implementation so I expect it to work. For x86, I've made sure to only fire the DMA bottom half if there is a DMA channel that is runnable. The effect of this is that unless you're using sb16 or a floppy disk, the DMA bottom half never fires. You probably should test this malc. My own benchmarks actually show slight improvement by it's possible the change in timing could affect your demos. Since v1, I've changed the code to use a BH instead of a timer. cris at least seems to depend on faster than 10ms polling.

2008-06-10ETRAX: More DMA context level related fixes.edgar_igl1-40/+70
* When hitting EOL (end of list) at the data descriptor level, the DMA should mark the current context-descriptor as disabled and perform a context-store so software can see whats goin on. * Context loads update RW_SAVED_DATA_BUF, data loads dont. This fixes an issue with ethernet bootstrapping. * Reorder the logic for processing out channels to be more like the one for input channels. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4723 c046a42c-6fe2-441c-8c8c-71466251a162
