* Break out stack(9) from ddb(4):Robert Watson2007-12-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | - Introduce per-architecture stack_machdep.c to hold stack_save(9). - Introduce per-architecture machine/stack.h to capture any common definitions required between db_trace.c and stack_machdep.c. - Add new kernel option "options STACK"; we will build in stack(9) if it is defined, or also if "options DDB" is defined to provide compatibility with existing users of stack(9). Add new stack_save_td(9) function, which allows the capture of a stacktrace of another thread rather than the current thread, which the existing stack_save(9) was limited to. It requires that the thread be neither swapped out nor running, which is the responsibility of the consumer to enforce. Update stack(9) man page.

* Jumbo-commit to enhance 32 bit application support on 64 bit kernels.Peter Wemm2005-06-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is good enough to be able to run a RELENG_4 gdb binary against a RELENG_4 application, along with various other tools (eg: 4.x gcore). We use this at work. ia32_reg.[ch]: handle the 32 bit register file format, used by ptrace, procfs and core dumps. procfs_*regs.c: vary the format of proc/XXX/*regs depending on the client and target application. procfs_map.c: Don't print a 64 bit value to 32 bit consumers, or their sscanf fails. They expect an unsigned long. imgact_elf.c: produce a valid 32 bit coredump for 32 bit apps. sys_process.c: handle 32 bit consumers debugging 32 bit targets. Note that 64 bit consumers can still debug 32 bit targets. IA64 has got stubs for ia32_reg.c. Known limitations: a 5.x/6.x gdb uses get/setcontext(), which isn't implemented in the 32/64 wrapper yet. We also make a tiny patch to gdb pacify it over conflicting formats of ld-elf.so.1. Approved by: re Notes: svn path=/head/; revision=147692

* - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) sourceMarius Strobl2005-06-101-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | files after they were repo-copied to sys/dev/atkbdc. The sources of atkbdc(4) and its children were moved to the new location in preparation for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in order to not further scatter them over the whole tree which would have been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another reason for the repo-copies was that some of the sources were misfiled, e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly. Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't ISA-specific. - Separate the parts of atkbdc_isa.c which aren't actually ISA-specific but are shareable between different atkbdc(4) bus front-ends into atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource() respectively in atkbdc_isa.c instead of rolling own versions. - Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for atkbdc(4). PS/2 controllers and input devices are used on a couple of Sun OEM boards and occur on either the EBus or the ISA bus. Depending on the board it's either the only on-board mean to connect a keyboard and mouse or an alternative to either RS232 or USB devices. - Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled without isa(4) (e.g. for EBus-only machines). This ISA-specific part isn't separated into its own source file, yet, as it requires more work than was feasible for 6.0 in order to do it in a clean way. Actually philip@ is working on a rewrite of psm(4) so a more comprehensive clean-up and separation of hardware dependent and independent parts is expected to happen after 6.0.

* Sanity the RTC code:Marcel Moolenaar2005-04-221-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | o Remove the clock interface. Not only does it conflict with the MI version when device genclock is added to the kernel, it was also not possible to have more than 1 clock device. This of course would have been a problem if we actually had more than 1 clock device. In short: we don't need a clock interface and if we do eventually, we should be using the MI one. o Rewrite inittodr() and resettodr() to take into account that: 1) We use the EFI interface directly. 2) time_t is 64-bit and we do need to make sure we can determine leap years from year 2100 and on. Add a nice explanation of where leap years come from and why. 3) This rewrite happened in 2005 so any date prior to 1/1/2005 (either M/D/Y or D/M/Y) is bogus. Reprogram the EFI clock with 1/1/2005 in that case. 4) The EFI clock has a high probability of being correct, so only (further) correct the EFI clock when the file system time is larger. That should never happen in a time-synchronised world. Complain when EFI lost 2 days or more. Replace the copyright notice now that I (pretty much) rewrote all of this file.

* Divorce critical sections from spinlocks. Critical sections as denoted byJohn Baldwin2005-04-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | critical_enter() and critical_exit() are now solely a mechanism for deferring kernel preemptions. They no longer have any affect on interrupts. This means that standalone critical sections are now very cheap as they are simply unlocked integer increments and decrements for the common case. Spin mutexes now use a separate KPI implemented in MD code: spinlock_enter() and spinlock_exit(). This KPI is responsible for providing whatever MD guarantees are needed to ensure that a thread holding a spin lock won't be preempted by any other code that will try to lock the same lock. For now all archs continue to block interrupts in a "spinlock section" as they did formerly in all critical sections. Note that I've also taken this opportunity to push a few things into MD code rather than MI. For example, critical_fork_exit() no longer exists. Instead, MD code ensures that new threads have the correct state when they are created. Also, we no longer try to fixup the idlethreads for APs in MI code. Instead, each arch sets the initial curthread and adjusts the state of the idle thread it borrows in order to perform the initial context switch. This change is largely a big NOP, but the cleaner separation it provides will allow for more efficient alternative locking schemes in other parts of the kernel (bare critical sections rather than per-CPU spin mutexes for per-CPU data for example).

We build uart(4) as a module on all platforms. This may break the ppc port. That depends on whether they do actually build modules. To use uart(4) on alpha, one must use the NO_SIO option.

* Revamp of the syscall path, exception and context handling. TheMarcel Moolenaar2003-05-161-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Remove special casing for running in the simulator from the kernelMarcel Moolenaar2003-02-011-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and instead add platform, firmware and EFI stubs to the loader. The net effect of this change is that besides a special console and disk driver, the kernel has no knowledge of the simulator. This has the following advantages: o Simulator support is much harder to break, o It's easier to make use of more feature complete simulators. This would only need a change in the simulator specific loader, o Running SMP kernels within the simulator. Note that ski at this time does not simulate IPIs, so there's no way to start APs. The platform, firmware and EFI stubs describe the following hardware: o 4 CPU Itanium, o 128 MB RAM within the 4GB address space, o 64 MB RAM above the 4GB address space. NOTE: The stubs in the skiloader describe a machine that should in parts be defined by the simulator. Things like processor interrupt block and AP wakeup vector cannot be choosen at random because they require interpretation by the simulator. Currently the simulator is ignorant of this. This change introduces an unofficial SSC call SSC_SAL_SET_VECTORS which is ignored by the simulator. Tested with: ski (version 0.943 for linux) Notes: svn path=/head/; revision=110211
