* Reserve a major number for use by the Iprobe device driver.Andrew Gallatin1999-01-181-1/+2
| | | | | | | | | | | | | | | | Iprobe is an alpha-only system profiling suite which I'm porting from Linux/alpha to FreeBSD. Iprobe works by using the hardware profiling support built into alpha cpus. In a nutshell, what Iprobe does is to setup the alpha performance counters to sample the pc at a fairly high rate & dumps those pc samples out to user space. Then some code runs to map the sampled PCs to functions. You get a bit more than that (like the PSL word, so you can tell if you're in the kernel or userland, what the ipl is, etc).

* Added support for the DEC EB64PLUS systype. (Part III)Andrew Gallatin1999-01-184-5/+10
| | | | | | | | | | | | o Add the EB64PLUS systype into the kernel configuration files and add it to the GENERIC kernel o Correct mcclock_isa.c's dependence on cia, it should depend on isa. This will allow avanti and eb64+ kernels to be built without the cia chipset support code. Notes: svn path=/head/; revision=42811

* Implement 'software completion' for floating point arithmetic. On theDoug Rabson1998-12-0410-14/+2622
| | | | | | | | | | | | | | | | | | | | | alpha, operations involving non-finite numbers or denormalised numbers or operations which should generate such numbers will cause an arithmetic exception. For programs which follow some strict code generation rules, the kernel trap handler can then 'complete' the operation by emulating the faulting instruction. To use software completion, a program must be compiled with the arguments '-mtrap-precision=i' and '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'. Programs compiled in this way can use non-finite and denormalised numbers at the expense of slightly less efficient code generation of floating point instructions. Programs not compiled with these options will receive a SIGFPE signal when non-finite or denormalised numbers are used or generated.
