xlnx_dp: Introduce a vblank signal

2022-06-08T18:38:47+00:00

Add a periodic timer which raises vblank at a frequency of 30Hz. Note that this is a migration compatibility break for the xlnx-zcu102 board type.

xlnx_dp: fix the wrong register size

2022-06-08T18:38:47+00:00

The core and the vblend registers size are wrong, they should respectively be 0x3B0 and 0x1E0 according to: https://www.xilinx.com/htmldocs/registers/ug1087/ug1087-zynq-ultrascale-registers.html. Let's fix that and use macros when creating the mmio region. Fixes: 58ac482a66d ("introduce xlnx-dp") Signed-off-by: Frederic Konrad Reviewed-by: Edgar E.

macfb: increase number of registers saved in MacfbState

2022-03-09T09:29:10+00:00

The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during initialisation and resolution changes. Whilst the function of many of these registers is unknown, it is worth the minimal cost of saving these extra values as part of migration to help future-proof the migration stream for the q800 machine as it starts to stabilise. Note this is a migration break, but since there are upcoming incompatible changes for the q800 machine (and migration does not even succeed without these patches) then this is not an issue.

macfb: don't use special irq_state and irq_mask variables in MacfbState

2022-03-09T09:29:10+00:00

The current IRQ state and IRQ mask are handled exactly the same as standard register accesses, so store these values directly in the regs array rather than having separate variables for them.

Introduce TYPE_VGA_MMIO, a sysbus device. While there is no change in the vga_mmio_init() interface, this is a migration compatibility break of the MIPS Acer Pica 61 Jazz machine (pica61).

macfb: add vertical blank interrupt

The MacOS driver expects a 60.15Hz vertical blank interrupt to be generated by the framebuffer which in turn schedules the mouse driver via the Vertical Retrace Manager.

macfb: add common monitor modes supported by the MacOS toolbox ROM

2021-10-08T11:31:03+00:00

The monitor modes table is found by experimenting with the Monitors Control Panel in MacOS and analysing the reads/writes. From this it can be found that the mode is controlled by writes to the DAFB_MODE_CTRL1 and DAFB_MODE_CTRL2 registers. Implement the first block of DAFB registers as a register array including the existing sense register, the newly discovered control registers above, and also the DAFB_MODE_VADDR1 and DAFB_MODE_VADDR2 registers which are used by NetBSD to determine the current video mode. These experiments also show that the offset of the start of video RAM and the stride can change depending upon the monitor mode, so update macfb_draw_graphic() and both the BI_MAC_VADDR and BI_MAC_VROW bootinfo for the q800 machine accordingly. Finally update macfb_common_realize() so that only the resolution and depth supported by the display type can be specified on the command line, and add an error hint showing the list of supported resolutions and depths if the user tries to specify an invalid display mode.

macfb: add qdev property to specify display type

2021-10-08T11:31:03+00:00

Since the available resolutions and colour depths are determined by the attached display type, add a qdev property to allow the display type to be specified. The main resolutions of interest are high resolution 1152x870 with 8-bit colour and SVGA resolution up to 800x600 with 24-bit colour so update the q800 machine to allow high resolution mode if specified and otherwise fall back to SVGA.
