So long story short: I need either the on-chip 32kHz timer OR the r4k timer if the 32kHz one is unusable, but not both, and r4k timer is useless when au1k_idle is in use. The current in-kernel Alchemy boards all work with the 32kHz timer, so I'm not against removing R4K_LIB symbols.

When poweroff machine, kernel_power_off() call disable_nonboot_cpus(). And if we have HOTPLUG_CPU configured, disable_nonboot_cpus() is not an empty function but attempt to actually disable the nonboot cpus. Since system state is SYSTEM_POWER_OFF, play_dead() won't be called and thus disable_nonboot_cpus() hangs. Therefore, we make this patch to avoid poweroff failure.

Rozycki" Date: Tue, 6 Mar 2012 20:28:54 +0000 Subject: MIPS: Handle COP3 Unusable exception as COP1X for FP emulation Our FP emulator is hardcoded for the MIPS IV FP instruction set and does not match the FP ISA with the general ISA. However for the few MIPS IV FP instructions that use the COP1X major opcode it relies on the Coprocessor Unusable exception to be delivered as a COP1 rather than COP3 exception. This includes indexed transfer (LDXC1, etc.) and FP multiply-accumulate (MADD.D, etc.) instructions. All the MIPS I, II, III and IV processors and some newer chips that do not implement the FPU use the COP3 exception however. Therefore I believe the kernel should follow and redirect any COP3 Unusable traps to the emulator unless an actual FPU part or core is present. This is a change that implements it. Any minor opcode encodings that are not recognised as valid FP instructions are rejected by the emulator and will result in a SIGILL signal being delivered as they currently do. We do not support vendor-specific coprocessor 3 implementations supported with MIPS I and MIPS II ISA processors; we never set CP0.Status.CU3. [Ralf: On MIPS IV processors the kernel always enables the XX bit which replaces the CU3 bit off earlier architecture revisions.] If matching between the CPU and the FPU ISA is considered required one day, this can still be done in the emulator itself. I think the CpU exception dispatcher is not the right place to do this anyway, as there are further differences between MIPS I, MIPS II, MIPS III, MIPS IV and MIPS32 FP ISAs. Corresponding explanation of this implementation is included within the change itself. Signed-off-by: Maciej W.
