* [PATCH] x86_64: Don't assume BSP has ID 0 in new smp bootupAndi Kleen2005-05-172-8/+14
| | | | | | | | | | | | | | | | | | | | | | | This patch removes the assumption that LAPIC entries contain the BSP as its first entry. This is a slight improvement to the temporary fix submitted by Suresh Siddha. - Removes assumption that LAPIC entries contain BSP first. - Builds x86_acpiid_to_apicid[] and bios_cpu_apicid[] properly with BSP as first entry. - Made maxcpus=1 boot on these systems. Since the parsing earlier in arch/x86_64/kernel/mpparse.c stopped after maxcpus entries, other entries were not processed, this causes kernel not to boot on these systems. TBD: x86_acpiid_to_apicid and bios_cpu_apicid[] seem to be exactly the same. This could be removed, but might need more work to cleanup.

* [PATCH] x86_64: Collected NMI watchdog fixes.Andi Kleen2005-05-173-79/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Collected NMI watchdog fixes. - Fix call of check_nmi_watchdog - Remove earlier move of check_nmi_watchdog to later. It does not fix the race it was supposed to fix fully. - Remove unused P6 definitions - Add support for performance counter based watchdog on P4 systems. This allows to run it only once per second, which saves some CPU time. Previously it would run at 1000Hz, which was too much. Code ported from i386 Make this the default on Intel systems. - Use check_nmi_watchdog with local APIC based nmi - Fix race in touch_nmi_watchdog - Fix bug that caused incorrect performance counters to be programmed in a few cases on K8. - Remove useless check for local APIC - Use local_t and per_cpu variables for per CPU data. - Keep other CPUs busy during check_nmi_watchdog to make sure they really tick when in lapic mode. - Only check CPUs that are actually online. - Various other fixes. - Fix fallback path when MSRs are unimplemented Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] x86_64: Add pmtimer supportAndi Kleen2005-05-175-19/+162
| | | | | | | | | | | | | | | | | | | | | | | | | | There are unfortunately more and more multi processor Opteron systems which don't have HPET timer support in the southbridge. This covers in particular Nvidia and VIA chipsets. They also don't guarantee that the TSCs are synchronized between CPUs; and especially with MP powernow the systems are nearly unusable because the time gets very inconsistent between CPUs. The timer code for x86-64 was originally written under the assumption that we could fall back to the HPET timer on such systems. But this doesn't work there. Another alternative is to use the ACPI PM timer as primary time source. This patch does that. The kernel only uses PM timer when there is no other choice because it has some disadvantages. Ported over from i386. It should be faster than the i386 version because I dropped the "read three times" workaround, but is still considerable slower than HPET and also does not work together with vsyscalls which have to be disabled.

* [PATCH] x86_64: Update TSC sync algorithmAndi Kleen2005-05-171-75/+182
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new TSC sync algorithm recently submitted did not work too well. The result was that some MP machines where the TSC came up of the BIOS very unsynchronized and that did not have HPET support were nearly unusable because the time would jump forwards and backwards between CPUs. After a lot of research ;-) and some more prototypes I ended up with just using the one from IA64 which looks best. It has some internal self tuning that should adapt to changing interconnect latencies. It holds up in my tests so far. I believe it was originally written by David Mosberger, I just ported it over to x86-64. See the inline comment for a description. This cleans up the code because it uses smp_call_function for syncing instead of having custom hooks in SMP bootup. Please note that the cycle numbers it outputs are too optimistic because they do not take into account the latency of WRMSR and RDTSC, which can be hundreds of cycles. It seems to be able to sync a dual Opteron to 200-300 cycles, which is probably good enough. There is a timing window during AP bootup where interrupts can see inconsistent time before the TSC is synced. It is hard to avoid unfortunately because we can only do the TSC sync after some setup, and we need to enable interrupts before that. I just ignored it for now.

* [PATCH] uml: Fix process exit raceBodo Stroesser2005-05-065-16/+11
| | | | | | | | | | | | | | | | | | | | | | | | tt-mode closes switch_pipes in exit_thread_tt and kills processes in switch_to_tt, if the exit_state is EXIT_DEAD or EXIT_ZOMBIE. In very rare cases the exiting process can be scheduled out after having set exit_state and closed switch_pipes (from release_task it calls proc_pid_flush, which might sleep). If this process is to be restarted, UML failes in switch_to_tt with: write of switch_pipe failed, err = 9 We fix this by closing switch_pipes not in exit_thread_tt, but later in release_thread_tt. Additionally, we set switch_pipe[0] = 0 after closing. switch_to_tt must not kill "from" process depending on its exit_state, but must kill it after release_thread was processed only, so it examines switch_pipe[0] for its decision.

Thus, setting/resetting of singlestepping is centralized in the new function set_singlestep(), which also inserts the macro SUBARCH_SET_SINGLESTEP(mode), if defined. Finally, s390 has the "ieee_instruction_pointer" in its registers, which also is allowed to be read via ptrace( PTRACE_PEEKUSER, getpid(), PT_IEEE_IP, 0); To implement this feature, sys_ptrace inserts the macro SUBARCH_PTRACE_SPECIAL, if defined.
