Replace this with an opt-in table that lists only the platforms that remain. This is effectively x86, plus a couple of historic workstation and server machines that reused parts of the x86 system architecture.

Now that we have a definite list of which architectures actually use it for what, use consistent #ifdef checks so the global variable is only defined when it is actually used on those architectures. On powerpc, there is no support for vgacon, but there is support for vga16fb. Loongarch and riscv have no support for vgacon or vga16fb, but they support EFI firmware, so only that needs to be checked, and the initialization can be removed because that is handled by EFI. IA64 has both vgacon and EFI.

Tracing this back in the historic git trees, this was used to match the size of VGA console or VGA framebuffer on early machines, but nowadays that code is no longer used, except probably on the old footbridge/netwinder since that is the only one that supports vgacon. On machines with a framebuffer, booting with DT so far results in always using the hardcoded 80x30 size in dummycon, while on ATAGS the setting can come from a bootloader specific override. Both seem to be worse choices than the Kconfig setting, since the actual text size for fbcon also depends on the selected font. Make this work the same way as everywhere else and use the normal Kconfig setting, except for the footbridge with vgacon, which keeps using the traditional code. If vgacon is disabled, footbridge can also ignore the setting. This means the screen_info only has to be provided when either vgacon or EFI are enabled now. To limit the amount of surprises on Arm, change the Kconfig default to the previously used 80x30 setting instead of the usual 80x25.

Miller" Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" From: Arnd Bergmann A number of architectures either kept the screen_info definition for historical purposes as it used to be required by the generic VT code, or they copied it from another architecture in order to build the VGA console driver in an allmodconfig build. Now that vgacon no longer builds on these architectures, remove the stale definitions.
