2020-06-30ati-vga: Add dummy MEM_SDRAM_MODE_REGBALATON Zoltan1-0/+1
Radeon chips have an SDRAM mode reg that is accessed by some drivers. We don't emulate the memory controller but provide some default value to prevent drivers getting unexpected 0.

2019-08-22ati-vga: Implement dummy VBlank IRQBALATON Zoltan1-0/+1
The MacOS driver exits if the card does not have an interrupt. If we set PCI_INTERRUPT_PIN to 1 then it enables VBlank interrupts and it boots but the mouse pointer cannot be moved. This patch implements a dummy VBlank interrupt triggered by a 60 Hz timer. With this the pointer now moves but MacOS still hangs somewhere before completely finishing boot.

2019-08-21ati-vga: Add some register definitions for debuggingBALATON Zoltan1-0/+4
Add names for AMCGPIO regs to make it easier to identify these in trace output. This is where rage128p has the DDC from the DVI port among others but because we don't implement the flat panel controller we don't want to connect an EDID here to make sure drivers use the VGA output instead. But since these are often probed by drivers it helps to see what happens by logging these registers by name.

2019-08-21ati-vga: Add registers for getting aperturesBALATON Zoltan1-0/+5
Some drivers (e.g. Linux radeon drm and MacOS) access these to find apertures to access card. Try to implement these but not sure these are correct yet.

2019-06-28ati-vga: Implement DDC and EDID info from monitorBALATON Zoltan1-0/+2
This adds DDC support to ati-vga and connects i2c-ddc to it. This allows at least MacOS with an ATI ndrv, Linux radeonfb and MorphOS to get monitor EDID info (although MorphOS splash screen is not displayed and radeonfb needs additional tables from vgabios-rv100). Xorg needs additional support from VESA vgabios, it's missing INT10 0x4F15 function (see https://gitlab.freedesktop.org/xorg/xserver/blob/master/hw/xfree86/vbe/vbe.c) without which no DDC is available that also prevents loading the accelerated X driver.

2019-03-11hw/display: Add basic ATI VGA emulationBALATON Zoltan1-0/+259
At least two machines, the PPC mac99 and MIPS fulong2e, have an ATI gfx chip by default (Rage 128 Pro and M6/RV100 respectively) and guests running on these and the PMON2000 firmware of the fulong2e expect this to be available. Fortunately these are very similar chips so they can be mostly emulated in the same device model. This patch adds basic emulation of these ATI VGA chips. While this is incomplete and currently only enough to run the MIPS firmware and get framebuffer output with Linux, it allows the fulong2e board to work more like the real hardware and having it in QEMU in this state provides a way to experiment with it and allows others to contribute to improve it. It is compiled for all archs but only the fulong2e (which currently has no display output at all) is set to use it by default (in a separate patch).
