This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.

Write kernel log output directly via the hypervisor console.
|
|
|
|
This is useful for kernel debugging when your machine crashes very
|
|
early before the console code is initialized. For normal operation
|
|
it is not recommended because it looks ugly and doesn't cooperate
|
|
with klogd/syslogd. You should normally N here,
|
|
unless you want to debug such a crash.

This option will cause messages to be printed if free stack space

drops below a certain limit.

Enables the display of the minimum amount of free stack which each

|
task has ever had available in the sysrq-T and sysrq-P debug output.

This option will slow down process creation somewhat.

Debug info can be large, and flags like
|
|
`-femit-struct-debug-baseonly' can reduce the kernel file
|
|
size and build time noticeably. Such flags are often
|
|
helpful if the main use of debug info is line number info.
