2019-08-22ati-vga: Implement dummy VBlank IRQBALATON Zoltan
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 limited support for big endian frame buffer apertureBALATON Zoltan
Set frame buffer endianness according to requested endianness for frame buffer apertures. We set frame buffer to big endian if any of the two apertures are set to big endian. Using different endianness for the two apertures is not implemented. This fixes inverted colors with MacOS and Xorg frame buffer driver but some Linux drivers may have endianness issues even on real hardware so this may not fix all cases. MorphOS uses aper0 in LE, Linux uses aper0 in BE and MacOS uses aper1 in BE but not sure about others or if MacOS also may need aper0 in which case we'll need a more complex fix but MacOS has other problems yet so for now this might work.

2019-07-03hw/i2c/bitbang_i2c: Use in-place rather than malloc'd bitbang_i2c_interface ↵Peter Maydell
struct Currently the bitbang_i2c_init() function allocates a bitbang_i2c_interface struct which it returns. This is unfortunate because it means that if the function is used from a DeviceState init method then the memory will be leaked by an "init then delete" cycle, as used by the qmp/hmp commands that list device properties. Since three out of four of the uses of this function are in device init methods, switch the function to do an in-place initialization of a struct that can be embedded in the device state struct of the caller. This fixes LeakSanitizer leak warnings that have appeared in the patchew configuration (which only tries to run the sanitizers for the x86_64-softmmu target) now that we use the bitbang-i2c code in an x86-64 config.

2019-06-28ati-vga: Fixes to offset and pitch registersBALATON Zoltan
Fix bit masks of registers for offset and pitch and also handle default values for both R128P and RV100. This improves picture a bit but does not resolve all problems yet so there might be some more bugs somewhere.

2019-06-28ati-vga: Implement DDC and EDID info from monitorBALATON Zoltan
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 Zoltan
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).
