mrph28 3b379b4435 feat(libkernel): answer kern.proc.proc with the calling process 
MihawkOS (PPSA99170) reads sysctl {1, 14, 8, 0} while it starts and the
runtime throws on the unsupported MIB, which aborts the title.

KERN_PROC_PROC takes no pid, so the node lists the one guest process the
runtime hosts, as the same kinfo_proc kern.proc.pid already builds.

MarcZX10 03a4bd851e docs(libkernel): sysctlnametomib returns ENOENT for kern.smp.maxcpus, kern.stackprot, kern.sched.name and kern.timecounter.hardware 
Old claim (entry 155 of docs/dev/debt/libkernel.md, second half): sysctlnametomib still throws for these four names.

What the code does: these names are only in IsUnansweredName, which the read path of sysctl uses. sysctlnametomib does not match them in TopLevelNode, its known-name table or its SystemStrings and SystemIntegers tables, so it reaches the final fall-through, sets errno to 2 (ENOENT) and returns -1 without throwing.

cocoa55andClaude Opus 5.5 9a7acb3677 fix(libkernel): spin and yield by the mutex spin and yield loop counts 
Lock and timed lock now try the mutex up to the spin count with a pause
between tries, then up to the yield count with a yield before each try,
before they block, as FreeBSD 11.4's mutex_lock_sleep does. Trylock and
a lock the thread already holds do not spin. A uniprocessor host skips
the spins and keeps the yields.

BunnyFlandClaude Opus 5.5 bf1a40404f docs(libkernel): correct what the firmware records for the AMM writers 
The PRT remap's last argument is checked but not recorded by firmware
13.42, and the comparison covered the recorded fields, not the bytes.

Oscar45397andClaude Opus 5.5 06b7a58b1b fix(libkernel): return ENOMEM when mapping unallocated direct memory 
Mapping a direct memory range that includes an unallocated physical
page threw std::invalid_argument and ended the process. It now returns
ENOMEM before anything is mapped, as shadPS4's MemoryManager::MapMemory
does.

Oscar45397andClaude Opus 5.5 287f43e004 fix(libkernel): return EFAULT for a null virtual range name 
KytyPS5 and shadPS4 return EFAULT for a null name. The test keeps that
and the rename and clear checks, and drops the null address, zero length
and past-the-end cases that no reference covers; the debt entry records
them as unknown, with the 32-byte name limit.

BunnyFlandClaude Opus 5.5 dd0bc0b781 feat(libkernel_sys): add the AMM writers for PRT maps, address and counter writes, waits and event queues 
sceKernelWriteMapCommand2, sceKernelWriteUnmapToPrtCommand,
sceKernelWriteWriteAddressCommand, sceKernelWriteWriteCounterCommand,
sceKernelWriteWaitOnAddressCommand, sceKernelWriteWaitOnCounterCommand
and sceKernelWriteEventQueueOnCompletionCommand follow the checks of
firmware 13.42's libkernel and record this project's command layout.
Without the PRT flag, sceKernelWriteMapCommand2 is
sceKernelWriteMapCommand, as on the console. The debt files record where
the existing writers' checks differ from the firmware.

Oscar45397andClaude Opus 5.5 03722a1570 fix(libkernel): deliver raises at the spin that ends a sleep on Windows 
On Windows a sleep shorter than TimedWait's 0.5 ms lead, and the last 0.5 ms of a longer one, is a YieldProcessor spin in host code with no wait counted. A raise that found the target there could only be delivered through the return-address breakpoint or sampling, so sceKernelRaiseException at a thread looping on such sleeps was lost: a thread looping on sceKernelUsleep(200) lost the first raise in 5 of 5 runs.

The spins in SleepUntil and SleepNanosUnlessChanged now run under a DeliveryDeferral and drain APCs afterwards, as BeginPark and Unpark already do. A raise that finds the target spinning is queued as an APC and runs when the sleep ends.

GuestRaiseShortSleep raises 100 times each at a thread sleeping 100, 200 and 400 us in a loop, with sleep wakes on (SleepNanosUnlessChanged) and with APS5_NO_SLEEP_WAKE (SleepUntil). Both fail on main at the first or second raise.
