eee0b7c3ff Kernel: Make ioctl take unsigned long instead of int
this is what linux does :D

also fix one or two `return ioctl` instead of `return ioctl_impl`

63b2284324 Kernel/LibC: support RDTSCP based clock_gettime
RDTSCP seems to be faster than LSL and it removes the need for getting
the current cpu twice to make sure TSC is read on the correct CPU

7219eac65f Kernel: Remove unnecessary page table validation
Processes always have a page table when they are initialized. This was
not true a long time ago when kernel threads could also be processes

0dc74beb0f Kernel/LibC: Allocate thread stacks in userspace
This adds support for pthread function for stack manipulation.

Also keep track of main threads stack in the uthread

991f7024d5 Kernel: Allow fork to fail at any point 2026-07-02 20:02:24 +03:00
6d1696b77e Kernel: Don't allocate userspace stacks in Thread
Thread only cares about stack's vaddr and size. Stacks are now allocated
before creating the threads.

b19b7f064a LibC: Make pthread_t pointer to uthread instead of a thread id
This will allow getting info about other threads in userspace!

f449ca8161 Kenrel: Separate pthread API from kernel API
It didn't really make sense for the syscalls to be named as the pthread
equivalents. Now the kernel just uses thread ids

5540bc4147 Kernel: Fix USB SCSI device naming 2026-07-02 20:02:24 +03:00
d8f136a76f Kernel: Remove the weird StorageController base class
This wasn't really used for anything and broke nvme controller as it was
now doubly ref counted :P

59c59c3316 Kernel: Expose stack base/size and page size in auxv 2026-07-02 20:02:24 +03:00
d241975ce1 Kernel: Remove SYS_SLEEP and cleanup SYS_NANOSLEEP
`sleep` is now implemented in terms of `nanosleep`. `nanosleep` is now
more precise and handles overflow when calculating wakeup time. I don't
think anything was depending on this, but I could see a program sleeping
for max time to block until signal.

20663b533b Kernel: Rework sleeping API
instead of sleep_{ns,ms} we now have sleep_{for,until}_{ns,ms}. This
makes code cleaner that just wants to sleep until some timestamp

f121e80bfd Kernel: Fix PROT_EXEC flags in sys_mprotect 2026-06-30 20:14:38 +03:00
4e28a35af9 Kernel: Support hardware checksum offload on RTL8169 receive 2026-06-30 20:14:38 +03:00
ddb7641b05 Kernel: Support hardware checksum offload on E1000 receive 2026-06-30 20:14:38 +03:00
a6ad9b9b2e Kernel: Add system for hardware checksum offload on received packets 2026-06-30 20:14:38 +03:00
c0bd07174d Kernel: Reduce the number of E1000 register reads while receiving
There is no need to read and write the receive tail pointer for every
packet. This change bumped my TCP speed from ~11MB/s to ~40MB/s which is
my network speed limit

8f4e15b78e Kernel: Use spinlocks and disable interrupts with loopback interface
This makes sure we don't get pre-empted after acquiring a descriptor but
before finishing marking it ready

aedd53b3e0 Kernel: Disable interrupts while appending packet in E1000
This avoids getting rescheduled and having other packets waiting to get
sent because of that
2026-06-30 20:14:37 +03:00
6339044e4c Kernel: Fix RTL8169 driver
This now works properly on real hardware. Main issue was a race
condition with now ISR was handled in the interrupt handler. We now loop
until we read back ISR as zero

6e47fa084b Kernel: Fix ext2 indirect block lookup math
This was broken for doubly and triply indirect blocks :D

59ec05c898 Kernel: Make TSC based timer monotonic
Prior to this I was just blindly rebasing the current TSC stats every
once in a while. Now I check for drift and scale the multiplier
accordingly to keep the timer from drifting

ac0ef53e87 Kernel: Fix HPET interrupt routing
If the HPET did not support legacy routing we would still use IRQ0 which
lead to using PIT irq which fired ~18 times per second

f3f40a465b Kernel: Fix HDA amplifier step size calculation
step size is zero based, 0 means 250 mdB

d3130884b6 Kernel: Hack TTY to work as debug console
debug printing takes the debug lock, but TTY uses mutex for its lock

98fd86477a Kernel: Remove allocations from path lookup
this bumped looped /usr/bin/ls stat performance from 750k->1100k/s
2026-05-26 19:10:16 +03:00
16a442f473 Kernel: Fix Thread::will_exit_because_of_signal
I was not checking whether the signal handler has been overwritten to
ignore the signal leading to infinite busy loops :)

585e021c7f Kernel: Don't panic when stack trace leads to GPF
if there is was a uncanonical address in stack trace we ended up in an
infinite recursive loop trying to print stack trace

previously it was only on the sockets

60484b286f Kernel: Fix bugs in sys_pselect
I was not validating nfds passed from userspace. Also invalid fds are
supposed to return EBADF instead of ignoring those entries

12158d9208 Kernel: Add OpenFileDescriptorSet::get_max_open_fd 2026-05-21 14:59:35 +03:00
