      graphical_console_init change (Stefano Stabellini) · 3023f332
      由 aliguori 提交于 
      Patch 5/7

This patch changes the graphical_console_init function to return an
allocated DisplayState instead of a QEMUConsole.

This patch contains just the graphical_console_init change and few other
modifications mainly in console.c and vl.c.
It was necessary to move the display frontends (e.g. sdl and vnc)
initialization after machine->init in vl.c.

This patch does *not* include any required changes to any device, these
changes come with the following patches.

Patch 6/7

This patch changes the QEMUMachine init functions not to take a
DisplayState as an argument because is not needed any more;

In few places the graphic hardware initialization function was called
only if DisplayState was not NULL, now they are always called.
Apart from these cases, the rest are all mechanical substitutions.

Patch 7/7

This patch updates the graphic device code to use the new
graphical_console_init function.

As for the previous patch, in few places graphical_console_init was called
only if DisplayState was not NULL, now it is always called.
Apart from these cases, the rest are all mechanical substitutions.

      Make DMA bottom-half driven (v2) · 492c30af
      由 aliguori 提交于 
      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.
