this raises performance of tcpbench on an m3000 from ~3kpps and ~8MB/s to ~70kpps and ~191MB/s when transmitting, and ~10kpps and ~15MB/s to ~120kpps and 174MB/s when receiving. i also tested this on a v245 and an m4000 a while back.

2021-01-14Some BIOS seem to provide memory regions <16M in their reserved memorypatrick1-5/+7
region reporting table. Since the extent only covered memory starting at 16M, these regions could not be reserved and would in turn cause a panic. Make the extent start at 0 and immediately reserve the first 16M right away, so that we can change the reserved memory allocator to EX_CONFLICTOK to make allocations succeed if they are already reserved. ok kettenis@

2021-01-11When an endpoint stalls, we usually try to reset it by callingmglocker1-2/+2
usbd_clear_endpoint_stall(), which in turn will call usbd_clear_endpoint_toggle(). It can be a common situation that when this happens, there is still a transfer in the stalled queue being in progress. The ehci(4) clear toggle function is currently doing a panic() in the diagnostic code in this situation, which is a bit of an overkill. The device still can be recovered by detaching/attaching it. Therefore change the panic() in to a printf(). ok mpi@

2021-01-08Bring the emulated Linux memory allocation interfaces more in line withkettenis3-39/+126
what Linux does. Let vmalloc() use km_alloc(9) instead of malloc(9) and let kvmalloc() only use malloc(9) for small (less than a page) allocations and atomic allocations. This should reduce the pressure on the "interrupt-safe" map. ok jsg@
2021-01-06Let a process open a video(4) device multiple timesjca1-7/+12
The previous behavior was conservative but a bit too restrictive. The V4L API lets several processes open a single video device, with exclusive access to certain methods when a process starts streaming. This is not trivial to implement. This small change fixes webcam usage with Firefox and BigBlueButton. Diff simplified + ok mglocker@, thanks!

2020-12-30Enter power-saving mode on POWER9 (ISA v3)gkoehler2-2/+19
When opal(4) attaches, look in the device tree for a psscr value. In cpu_idle_cycle(), use this psscr value and the stop instruction to wait for the next interrupt. In mp kernels, cpu_unidle() now sends an interrupt. In "sysctl hw.sensors", the power and temperature sensors from opalsens(4) may show lower values. The cpu may exit stop at the system reset vector after losing user registers. If so, restore some registers. For now, ignore deeper stop states that would lose hypervisor registers. Our mp kernel uses only the first hardware thread of each core. Take the extra threads from the firmware and stop them forever; this may switch the core from SMT4 to single-thread mode and increase performance. partly by kettenis@, ok kettenis@
