* Repair some races in IPI handling:Nathan Whitehorn2014-05-123-2/+23
| | | | | | | | | | | | | | | | | 1. Make sure IPI mask is set before sending the IPI 2. Operate atomically on PS3 PIC outstanding interrupt list 3. Make sure IPIs are EOI'ed before, not after, processing. Without this, a second IPI could be sent partway through processing the first one, get erroneously acknowledge by the EOI to the first, and be lost. In particular in the case of smp_rendezvous(), this can be fatal. In combination, this makes the PS3 boot SMP again. It probably also fixes some latent bugs elsewhere.

* Rename global cnt to vm_cnt to avoid shadowing.Bryan Drewery2014-03-224-7/+7
| | | | | | | | | | | | | | | | | To reduce the diff struct pcu.cnt field was not renamed, so PCPU_OP(cnt.field) is still used. pc_cnt and pcpu are also used in kvm(3) and vmstat(8). The goal was to not affect externally used KPI. Bump __FreeBSD_version_ in case some out-of-tree module/code relies on the the global cnt variable. Exp-run revealed no ports using it directly.

* Mask out SRR1 bits that aren't exported to the MSR.Justin Hibbits2014-03-211-1/+3
| | | | | | | | | | | | | This appears to fix a strange condition with X on 32-bit PowerBooks I observed, caused by one of these bits getting set in the mcontext, but not set in the thread, which may be a symptom of another problem, more difficult to diagnose. Since these bits aren't exported anyway, this change makes it more explicit that the bits aren't MSR-related in SRR1. MFC after: 3 weeks Notes: svn path=/head/; revision=263464

When the ofw_bus_map_intr() API was introduced, it assumed that, as on most systems, these were either 1 cell, containing an interrupt line, or 2, containing a line number plus a sense code. It turns out a non-negligible number of ARM systems use 3 (or even 4!) cells for interrupts, so make this more general. Notes: svn path=/head/; revision=261351
* Add hwpmc(4) support for the PowerPC 970 class processors, direct events.Justin Hibbits2014-02-012-15/+22
| | | | | | | | | | | | | | This also fixes asserts on removal of the module for the mpc74xx. The PowerPC 970 processors have two different types of events: direct events and indirect events. Thus far only direct events are supported. I included some documentation in the driver on how indirect events work, but support is for the future.

Since 32-bit set_context can't change those bits anyway, copy the ones from the current context (td->td_frame) before calling set_context(). MFC after: 3 weeks Notes: svn path=/head/; revision=261095

| | | | | | | | | | | | | | | This is the first step needed to get the snapper codec working on those machines. The second step is to enable the corresponding I2S device and its clock. Tested on machines where the snapper codec was already working, a G4 PowerBook and a PowerMac9,1 with a Shasta based macio. The PowerMac7,2/7,3 with a K2 based macio can now also play sound.

* Retire machine/fdt.h as a header used by MI code, as its function is nowNathan Whitehorn2014-01-051-41/+0
| | | | | | | | | | | | | | | | | | obsolete. This involves the following pieces: - Remove it entirely on PowerPC, where it is not used by MD code either - Remove all references to machine/fdt.h in non-architecture-specific code (aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat non-arch-specific). - Fix code relying on header pollution from machine/fdt.h includes - Legacy fdtbus.c (still used on x86 FDT systems) now passes resource requests to its parent (nexus). This allows x86 FDT devices to allocate both memory and IO requests and removes the last notionally MI use of fdtbus_bs_tag. - On those architectures that retain a machine/fdt.h, unused bits like FDT_MAP_IRQ and FDT_INTR_MAX have been removed.
