| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | passing a pointer to an opaque clockframe structure and requiring the MD code to supply CLKF_FOO() macros to extract needed values out of the opaque structure, just pass the needed values directly. In practice this means passing the pair (usermode, pc) to hardclock() and profclock() and passing the boolean (usermode) to hardclock_cpu() and hardclock_process(). Other details: - Axe clockframe and CLKF_FOO() macros on all architectures. Basically, all the archs were taking a trapframe and converting it into a clockframe one way or another. Now they can just extract the PC and usermode values directly out of the trapframe and pass it to fooclock(). - Renamed hardclock_process() to hardclock_cpu() as the latter is more accurate. - On Alpha, we now run profclock() at hz (profhz == hz) rather than at the slower stathz. - On Alpha, for the TurboLaser machines that don't have an 8254 timecounter, call hardclock() directly. This removes an extra conditional check from every clock interrupt on Alpha on the BSP. There is probably room for even further pruning here by changing Alpha to use the simplified timecounter we use on x86 with the lapic timer since we don't get interrupts from the 8254 on Alpha anyway. - On x86, clkintr() shouldn't ever be called now unless using_lapic_timer is false, so add a KASSERT() to that affect and remove a condition to slightly optimize the non-lapic case. - Change prototypeof arm_handler_execute() so that it's first arg is a trapframe pointer rather than a void pointer for clarity. - Use KCOUNT macro in profclock() to lookup the kernel profiling bucket.

| | | | | | | | | | | | | | if the boot CPU has a local APIC because some BIOS vendors are not competent enough to set this bit. Instead, just assume that we always have a local APIC on amd64. For i386 the check is a bit more subtle. FreeBSD requires either an MP Table or an ACPI MADT table to enumerate APICs. The only systems that have one of those tables that don't have local APICs are some presumably rare (and old) SMP 486 systems using external APICs. Thus, instead of checking the CPUID_APIC flag, check the CPU class and abort if we are running on a 486. MFC after: 1 week Reported by: bz

| | | | | | | | | | | | | working IRQ0 with APIC anymore. Previously, it was possible to have some other ATPIC IRQS "leak" through in a few edge cases. For example, on my x86 test machine, ACPI re-routes the SCI (IRQ 9) to intpin 13 on the first I/O APIC. This leaves a hole for IRQ 13 (since the APIC doesn't provide a source for IRQ 13 in that case) with the result that the ATPIC IRQ13 source was registered instead. This changes the 8259A drivers to only register their interrupt sources if none of the 16 ISA IRQs have an interrupt source already installed. MFC after: 1 week

This is especially useful since PUC_FASTINTR hangs the kernel boot on my ultra60 which has two uart(4) devices hung off of a puc(4) device. I did not enable PUC_FASTINTR by default on powerpc since powerpc does not currently allow sharing of INTR_FAST with non-INTR_FAST like the other archs.

Now we do a full reset of the 8259As and setup a simple interrupt handler (we actually borrow the apic one that just does an immediate iret) to handle any spurious interrupts triggered by either chip. This should fix some folks that were getting a Trap 30 during bootup of certain SMP AMD systems. This might get pushed into the 6.0 branch as an errata.

Additionally, limit the reclamation to inactive pages unless allocation from the PV entry zone or reclamation from the inactive queue fails. Previously, reclamation destroyed mappings to both inactive and active pages. get_pv_entry() still, however, wakes up the page daemon when reclamation occurs. The reason being that the page daemon may move some pages from the active queue to the inactive queue, making some new pages available to future reclamations. Print the "reclaiming PV entries" message at most once per minute, but don't stop printing it after the fifth time. This way, we do not give the impression that the problem has gone away.

* Begin and end the initialization of pvzone in pmap_init().alc2005-11-041-19/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, pvzone's initialization was split between pmap_init() and pmap_init2(). This split initialization was the underlying cause of some UMA panics during initialization. Specifically, if the UMA boot pages was exhausted before the pvzone was fully initialized, then UMA, through no fault of its own, would use an inappropriate back-end allocator leading to a panic. (Previously, as a workaround, we have increased the UMA boot pages.) Fortunately, there is no longer any reason that pvzone's initialization cannot be completed in pmap_init(). Eliminate a check for whether pv_entry_high_water has been initialized or not from get_pv_entry(). Since pvzone's initialization is completed in pmap_init(), this check is no longer needed. Use cnt.v_page_count, the actual count of available physical pages, instead of vm_page_array_size to compute the maximum number of pv entries. Introduce the vm.pmap.pv_entries tunable on alpha and ia64. Eliminate some unnecessary white space. Discussed with: tegge (item #1) Tested by: marcel (ia64)

| | | | | | | | | | | | | | | | source is first enabled similar to how intr_event's now allocate ithreads on-demand. Previously, we would map IDT vectors 1:1 to IRQs. Since we only have 191 available IDT vectors for I/O interrupts, this limited us to only supporting IRQs 0-190 corresponding to the first 190 I/O APIC intpins. On many machines, however, each PCI-X bus has its own APIC even though it only has 1 or 2 devices, thus, we were reserving between 24 and 32 IRQs just for 1 or 2 devices and thus 24 or 32 IDT vectors. With this change, a machine with 100 IRQs but only 5 in use will only use up 5 IDT vectors. Also, this change provides an API (apic_alloc_vector() and apic_free_vector()) that will allow a future MSI interrupt source driver to request IDT vectors for use by MSI interrupts on x86 machines.
