Bananymous 7c57d736c6 Kernel/LibC: Fix dirent functions
dirent functions used to fail if a directory contained more than 128
files :D

Bananymous cbe3f2a4ac BuildSystem: Cleanup and fix cmake files
I now set library SONAME so i don't have to build them in build root.

Creating font now makes sure the install directory exists. This allows
building using make files.

LibC now links agains ligcc

Bananymous 7a10e0e347 Kernel: Fix TmpFS inode linking
TmpFS now looks for empty entries in directories instead of always
appending files to the end of directories. This makes kernel not crash
after process pid 126 is created :D

Bananymous cbcb9f9044 Kernel: Warn on unsupport `clock_gettime` `clock_id`s 2025-01-25 17:31:17 +02:00
Bananymous 2a16a67aed Kernel: Ignore SA_RESTART flag on sigaction
This is a big hack but a lot of ports set this flag. This seems really
annoying to implement properly

Bananymous ee078fc638 Kernel: Fix fd status/descriptor flag handling
I was not sharing status and offset on fork and I was sharing descriptor
flags on dup/dup2

Bananymous 9893c90e74 Kernel: Remove SYS_DUP and implement it using fcntl F_DUPFD 2025-01-17 19:29:47 +02:00

Bananymous 80ce9d546a Kernel: Don't error out on SYS_WAIT with W{CONTINUED,UNTRACED}
As I don't support stopping and continuing processes these flags are
effecively no-ops

Bananymous 34775633b2 Kernel: Clear DF on every interrupt handler
I was missing this and it lead to UB with my new mem* functions that
were implemented with `rep`

Bananymous ebecbb69ec LibC: Implement some mem* and str* functions in assembly
This made them a lot faster on modern cpus with optimized rep stos and
rep movs

Bananymous a5cf92b2ff Kernel: Use uint64_t instead of size_t for AML node conversion
This allows 32 bit to compile again :)

Bananymous 69137cddab Kernel: Implement TIOCSWINSZ for pseudo terminals
I have no idea how I had forgotten this

Bananymous d7b4f54983 Kernel: Check Control Method Battery _STA bit 4
This bit indicates wheter the battery is actually present.

Bananymous 3a6cdfff45 Kernel: Fix ACPI namespace initialization
Now _REG, _STA, _INI are called in the order my laptop expects them to
be called. This was kinda weird because what uACPI was doing did not
work.

\_SB_.PCI0.LPC0.EC0_.BAT0._STA required \_SB_.PCI0.LPC0.EC0_._REG to be
called
\_SB_.PCI0.LPC0.EC0_._REG required \_SB_.PCI0._STA to be called

Now I call all the _REG methods of a device after calling _STA/_INI and
after performing the whole _STA/_INI sequence i call rest of missing
_REG functions

Bananymous 4e364bd2f6 Kernel: Add support for ACPI Control Method Batteries
The implementation is kinda weird but it exposes some battery
information to userspace!

Bananymous 869f4011a1 Kernel: Replace the old AML interpreter by a new, better one
The old AML interpreter was trash and did not follow value/reference
semantics at all. It was also super slow, one of my machines taking over
7 seconds to parse ACPI namespace and call _INI and _STA.

Bananymous 3bf57e0748 Kernel: Add . and .. entries to /proc/<pid> directories
This allows to run `cd ..` in one of these directories

Bananymous 51b6329c86 Kernel: Make backspace \b and delete 0x7F
This is what `vim` seems to expect and imo makes way more sense.

Bananymous 49133dce48 Kernel: Make pipe check data every 100ms
This prevents dead lock if read-end does not detect data before blocking
why write-end already notified.

Bananymous 0a5aacfd87 Kernel: Allow open with O_CREAT bypass file permission checks
call to open(path, O_CREAT|O_EXCL|O_RDWR, 0444) should open file as
read-write although file is created as read-only on filesystem.

Bananymous 67e9ca56ac Kernel: Create /dev/urandom -> /dev/random symlink
Most software uses urandom instead of random so this allows it work
normally.

Bananymous 415b20f884 LibC: Remove errno EEXISTS
I don't know why I had added this. It doesn't seem to be a thing on
either POSIX or linux. This was literally equivalent to EXIST
