Grackle allows attaching different PCI devices. This change allows attach multiple of the same PCI device. To make the name unique in the machine map, the name of the PCI slot is appended to the device name.
There are cases where when it's necessary (e.g. given uninitialized NVRAM,
the Beige G3 with the 10.2 install CD inserted will update the boot
device and restart to boot from it).
Restart support was done by wrapping the ppc_exec function in a loop and
checking for a restart power off reason. We also need to disconnect all
event listeners, since they will be recreated when the machine is
re-initialized.
Add MPC601 variants. Variants that decrement and test the ctr are invalid bon't don't appear to trigger an exception. The manual says MPC601 can decrement the counter. Other CPUs do not decrement the counter but will branch based on the value.
PDM defaults to 640x480.
If you set --mon_id to MacRGB12in then it would draw 512x384 inside a 640x480 window.
If you set --mon_id to Multiscan20in then it would try to draw 832x624 inside a 640x480 window and crash.
If you set the Monitors control panel to switch multiscan display from 640x480 to 832x624 and restart then it would crash.
Now it will correctly change the window size every time the mode changes.
- Add all the interrupts including DMA.
- Modify the Interrupt to IRQ_ID translation so the interrupts belonging to the first set of 32 interrupts don't need to be shifted.
Add pixel format and pixel clock to the list of fields that will initiate a recalculation.
If frame rate is less than 24 or greater than 120 then assume 60Hz.
Consider write-only bits: ATI_CLOCK_STROBE can't be read so clear it.
8 bits at Offset 2 is PLL_DATA. If we don't modify PLL_DATA, then insert the current value of PLL_DATA into the value that will be read from ATI_CLOCK_CNTL.
When checking if a particular byte of a register is accessed, check both the starting position (offset) and ending position (offset + size) of the bytes being access.
- Add BAR 2 decode. This BAR isn't actually used by Mac OS X, but decode it anyway just in case.
- Support updating of BARs (using change_one_bar method).
pixel_format is different than pixel_depth.
pixel_format depends on the GPU. A GPU might have multiple formats for the same depth.
We store this in videoctrl so that we can detect changes in pixel_format like we do for pixel_depth and active_width and active_height.
