Make sure any errors that occur within the macfb realize chain are detected
and handled correctly to prevent crashes and to ensure that error messages are
reported back to the user.

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
As per the current Error API best practices, change macfb_commom_realize() to return
a boolean indicating success to reduce errp boiler-plate handling code. Note that
memory_region_init_ram_nomigrate() is also updated to use &error_abort to indicate
a non-recoverable error, matching the behaviour recommended after similar
discussions on memory API failures for the recent nubus changes.

During realize memory_region_init_ram_nomigrate() is used to initialise the RAM
memory region used for the framebuffer but the owner object reference is
incorrect since MacFbState is a typedef and not a QOM type.
Change the memory region owner to be the corresponding DeviceState to fix the
issue and prevent random crashes during macfb_common_realize().

The palette_current index counter has a maximum size of 256 * 3 to cover a full
color palette of 256 RGB entries. Linux assumes that the palette_current index
wraps back around to zero after writing 256 RGB entries so ensure that
palette_current is reset at this point to prevent data corruption within
MacfbState.

Currently macfb_common_realize() defines the framebuffer RAM memory region as
being non-migrateable but then immediately registers it for migration. Replace
memory_region_init_ram_nomigrate() with memory_region_init_ram() which is clearer
and does exactly the same thing.

The MacOS toolbox ROM uses the monitor sense to detect the display type and then
offer a fixed set of resolutions and colour depths accordingly. Implement the
monitor sense using information found in Apple Technical Note HW26: "Macintosh
Quadra Built-In Video" along with some local experiments.
Since the default configuration is 640 x 480 with 8-bit colour then hardcode
the sense register to return MACFB_DISPLAY_VGA for now.

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
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.

To: qemu-devel; +Cc: Mark Cave-Ayland, Laurent Vivier
From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
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.

We pass the old value of 'list' to g_strconcat(), which allocates
new memory and returns it; the 'list = ' overwrites the old 'list'
value. So the old string is leaked, because g_strconcat() won't
free it for you.
Coverity also complains that we pass NULL as argument 2 to
g_strconcat() the first time through the loop and this is bad;
I'm not sure whether it's wrong or not.
This function might be better written to use GString and
g_string_append_printf() to add each line to the GString.

According to Apple Technical Note HW26: "Macintosh Quadra Built-In Video" the
in-built framebuffer encodes each 24-bit pixel into 4 bytes. Adjust the 24-bit
RGB pixel encoding accordingly which agrees with the encoding expected by MacOS
when changing into 24-bit colour mode.

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

Whilst the in-built Quadra 800 framebuffer exists within the Nubus address
space for slot 9, it has its own dedicated interrupt on VIA2. Force the
macfb device to occupy slot 9 in the q800 machine and wire its IRQ to the
separate video interrupt since this is what is expected by the MacOS
interrupt handler.
