2015-09-20mac_dbdma: always clear FLUSH bit once DBDMA channel flush is completeMark Cave-Ayland
The code to flush the DBDMA channel was effectively duplicated in dbdma_control_write(), except for the fact that the copy executed outside of a RUN bit transition was broken by not clearing the FLUSH bit once the flush was complete. Newer PPC Linux kernels would timeout waiting for the FLUSH bit to clear again after submitting a FLUSH command. Fix this by always clearing the FLUSH bit once the channel flush is complete and removing the repeated code.

2015-07-07macio: remove nonexistent interrupt on pin 1Cormac O'Brien
The current macio implementation declares an interrupt that doesn't appear to exist in the hardware or any other emulator implementation. OpenBIOS detects this interrupt and generates an 'interrupts' property in the macio device tree entry. Mac OS 9 halts boot when it detects this interrupt, so it has been removed to permit further progress in the boot process.

2014-09-08PPC: Cuda: Use cuda timer to expose tbfreq to guestAlexander Graf
Mac OS X calibrates a number of frequencies on bootup based on reading tb values on bootup and comparing them to via cuda timer values. The only variable we can really steer well (thanks to KVM) is the cuda frequency. So let's use that one to fake Mac OS X into believing the bus frequency is tbfreq * 4. That way Mac OS X will automatically calculate the correct timebase frequency. With this patch and the patch set I posted earlier I can successfully run Mac OS X 10.2, 10.3 and 10.4 guests with -M mac99 on TCG and KVM.

2014-09-08PPC: mac99: Fix core99 timer frequencyAlexander Graf

2014-06-16macio: Fix timer endiannessAlexander Graf

2014-06-16macio ide: Do remainder access asynchronouslyAlexander Graf
The macio IDE controller has some pretty nasty magic in its implementation to allow for unaligned sector accesses. We used to handle these accesses synchronously inside the IO callback handler. However, the block infrastructure changed below our feet and now it's impossible to call a synchronous block read/write from the aio callback handler of a previous block access. Work around that limitation by making the unaligned handling bits also go through our asynchronous handler. This fixes booting Mac OS X for me.
