Привет всем,
У меня вопрос, почему на amd64 vesa-tng в gentoo-sources отсутсвует, а в томже ядре для x86 есть (я про make menuconfig ) ?

Идём вот сюда:
/usr/src/linux/Documentation/fb
и в файлике vesafb.txt читаем следующее:
| Quote: | The VESA framebuffer driver comes in two flavors - the standard vesafb
and vesafb-tng. Vesafb-tng is available only on 32-bit x86 due to the
technology it uses (vm86). |
А также вот это:
| Quote: | If your system doesn't support vm86 calls yet (all 64-bit platforms), things
get a little more tricky. Since on such systems you can't do BIOS calls from
protected mode in which kernel runs, you have to decide at boot time whenever
you want to run in text or in graphics mode. Switching mode later on is
impossible. Switching modes is done using the vga=... boot parameter. Read
Documentation/svga.txt for details. Below is a more detailed description of
what to do on systems using the standard vesafb driver. |
