Joystick axis and buttons are now named to standard values, this allows
interfacing multiple different controllers (only DS3 is supported)
Add ioctl calls for userspace to set joystick player leds and rumble
Only use DS3 code paths when we detect that the attached device is
actually an DS3 controller
update test-joystick program to the new interface and add support to
control rumble and player leds
Before this real hardware failed to boot with smp enabled. Allocating
the idle thread does a page mapping which ends up broadcasting TLB
shootdown to other processes. This ends up failing somewhere halting the
processors never allowing them to initialize their scheduler
Each allocated inode used to call sync(). Each sync reads and writes
a block from the filesystem. Doing a 1 MiB write ended up syncing around
257 times
Memory regions are now stored in a sorted array. This allows O(nlogn)
lookup for address validation instead of the old linear lookup.
Now inserting new regions is also O(nlogn) instead of the old constant
time, but lookups are **much** more frequent
Memory regions are now splitted when they get munmapped, mprotected, or
mmapped with MAP_FIXED. This is used by couple of ports, and without
this we were just leaking up memory or straight up crashing programs.
This also removes the now old recvfrom and sendto syscalls. These are
now implemented as wrappers around recvmsg and sendmsg.
Also replace unnecessary spinlocks from unix socket with mutexes
I had a hardlimit of 10 block buffers and if they ran out, the kernel
would crash. this patchs increases the number of buffers to 16 and
removes the crash condition when they run out :D
This moves processor array to .bss reducing data size by 8192 bytes :)
This needed GCC updated to 15.2.0 because of an internal compiler error
I found :)
Some stuff tries to use shared futexes so make them all shared. Private
futexes would be faster as they are process specific but supporting both
would need some reworks
