- EBADCPU is returned is scheduler tries to run a process on a CPU that either does not exist or isn't booted - this change was originally meant to deal with stupid cpuid instruction which provides totally useless information about hyper-threading and MPS which does not deal with ht at all. ACPI provides correct information. If ht is turned off it looks like some CPUs failed to boot. Nevertheless this patch may be handy for testing/benchmarking in the future.

/* The <errno.h> header defines the numbers of the various errors that can
|
|
* occur during program execution. They are visible to user programs and
|
|
* should be small positive integers. However, they are also used within
|
|
* MINIX, where they must be negative. For example, the READ system call is
|
|
* executed internally by calling do_read(). This function returns either a
|
|
* (negative) error number or a (positive) number of bytes actually read.
|
|
*
|
|
* To solve the problem of having the error numbers be negative inside the
|
|
* the system and positive outside, the following mechanism is used. All the
|
|
* definitions are are the form:
|
|
*
|
|
* #define EPERM (_SIGN 1)
|
|
*
|
|
* If the macro _SYSTEM is defined, then _SIGN is set to "-", otherwise it is
|
|
* set to "". Thus when compiling the operating system, the macro _SYSTEM
|
|
* will be defined, setting EPERM to (- 1), whereas when when this
|
|
* file is included in an ordinary user program, EPERM has the value ( 1).
