* Rough implement of makecontext() needed to support libthr.Marcel Moolenaar2003-05-312-1/+122
| | | | | | | | | | | | | | | | | o Up to 8 arguments are allowed. This is the number of arguments passed in registers. Subsequent registers are passed on the stack. Trying to deal with this is not easy in C and likely forces us to use assembly code. Let's avoid that for now. There's no indication that more than 8 arguments is a strong requirement (Linux also has an 8 argument limit). o We expect that the stack base is 16-byte aligned and the stack size is a multiple of 16-byte. We bomb out if this is not the case. We probably want to be less strict by enforcing it ourselves. For now it's better to not hide gross alignment bogons by silently correcting it.

* Fix amd(8) clients, if a FreeBSD mountd(8) server is used.Martin Blapp2003-05-281-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the special treatment of non-blocking mode in the "look ahead function" xdrrec_eof(). It currently assumes that the last read() in a row of several reads does not have zero lenght. If this is the case, svc_vc_stat() does return XPRT_MOREREQS, and the RPC-request aborts because there is no data to read anymore. To fix this, go back to the original version of the code for non-blocking mode until NetBSD comes up with another possible fix like this one in xdrrec_eof() if (rstrm->last_frag && rstrm->in_finger == rstrm->in_boundry) { return TRUE; } Return always FALSE in set_input_fragment() for non-blocking mode. Since this was not used in FreeBSD, I omitted it at the first time. Now we use this function and we should always return FALSE for it.

* Revamp of the syscall path, exception and context handling. TheMarcel Moolenaar2003-05-163-12/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | prime objectives are: o Implement a syscall path based on the epc inststruction (see sys/ia64/ia64/syscall.s). o Revisit the places were we need to save and restore registers and define those contexts in terms of the register sets (see sys/ia64/include/_regset.h). Secundairy objectives: o Remove the requirement to use contigmalloc for kernel stacks. o Better handling of the high FP registers for SMP systems. o Switch to the new cpu_switch() and cpu_throw() semantics. o Add a good unwinder to reconstruct contexts for the rare cases we need to (see sys/contrib/ia64/libuwx) Many files are affected by this change. Functionally it boils down to: o The EPC syscall doesn't preserve registers it does not need to preserve and places the arguments differently on the stack. This affects libc and truss. o The address of the kernel page directory (kptdir) had to be unstaticized for use by the nested TLB fault handler. The name has been changed to ia64_kptdir to avoid conflicts. The renaming affects libkvm. o The trapframe only contains the special registers and the scratch registers. For syscalls using the EPC syscall path no scratch registers are saved. This affects all places where the trapframe is accessed. Most notably the unaligned access handler, the signal delivery code and the debugger. o Context switching only partly saves the special registers and the preserved registers. This affects cpu_switch() and triggered the move to the new semantics, which additionally affects cpu_throw(). o The high FP registers are either in the PCB or on some CPU. context switching for them is done lazily. This affects trap(). o The mcontext has room for all registers, but not all of them have to be defined in all cases. This mostly affects signal delivery code now. The *context syscalls are as of yet still unimplemented. Many details went into the removal of the requirement to use contigmalloc for kernel stacks. The details are mostly CPU specific and limited to exception_save() and exception_restore(). The few places where we create, destroy or switch stacks were mostly simplified by not having to construct physical addresses and additionally saving the virtual addresses for later use. Besides more efficient context saving and restoring, which of course yields a noticable speedup, this also fixes the dreaded SMP bootup problem as a side-effect. The details of which are still not fully understood. This change includes all the necessary backward compatibility code to have it handle older userland binaries that use the break instruction for syscalls. Support for break-based syscalls has been pessimized in favor of a clean implementation. Due to the overall better performance of the kernel, this will still be notived as an improvement if it's noticed at all. Approved by: re@ (jhb) Notes: svn path=/head/; revision=115084
