Last change on this file since 17ccb9d7 was da52547, checked in by Martin Decky <martin@…>, 15 years ago

add early_putchar() which can be used to do early kernel console output for debugging purposes
(the availability of this feature depends on each platform and specific configuration, currently it works only on ia32/amd64 with EGA and no framebuffer)
instrument more kernel functions
mark some functions as no_instrument (context_restore(), overlaps(), main_bsp())
