* Use the .bss for the bootstrap stack of mips_init(). This way the memoryvisa2019-05-052-9/+24
| | | | | | | | region is properly allocated by the firmware. Move the .bss clearing to locore.S because the section has to be ready when the stack is taken into use. This additionally makes the C environment more consistent at the start of mips_init().

|
* Fix the balancing of work queue interrupts.visa2019-03-141-2/+2
| | | | | | | | | | | | | | | The value of `ncpusfound' no longer reflects the number of cores that will be utilized by the kernel; it can be larger if secondary cores have not been enabled by the firmware. This can lead to incorrect assignment of work queue interrupts, making certain cnmac(4) ports unable to receive packets. This is a regression introduced in r1.108 of octeon/machdep.c. Correct the problem by using `ncpus' for the balancing. All secondary cores have been attached and the value is final by the time work queue interrupt handlers are set up.

* Use SMR instead of reference counting for session reclamation.visa2019-03-101-17/+25
| | | | | This reduces the need of atomic operations. The lookup tree still requires serialization, though.

| | | | | | | | | it assumes that it always followed an interrupt string, but we don't print that on fdt. having the bus responsible for the whitespace means the fdt glue can print a colon to separate the bus info from checkrev output, while every other glue keeps the comma. ok deraadt@

* Figure out the number of available CPUs using system fuse registers.visa2018-12-182-4/+18
| | | | | | | | | | This makes `ncpusfound' independent of kernel boot parameters. The kernel still needs the help of the firmware to spin up secondary CPUs, so the `coremask' or `numcores' boot parameter is still needed for multicore operation. Tested on CN5020, CN6120, CN7130 and CN7360.

* Fix pool ipl to prevent a deadlock scenario.visa2018-12-161-2/+2
| | | | | While here, make the pool use the default memory alignment. The default setting is good enough for the driver and the hardware.
