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
 2025-01-24 19:34:22 +02:00
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
 2025-01-17 20:12:04 +02:00
Bananymous 9893c90e74 Kernel: Remove SYS_DUP and implement it using fcntl F_DUPFD 2025-01-17 19:29:47 +02:00
Bananymous 82978da5e3 Kernel: Cleanup AML code 2025-01-17 16:20:00 +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
 2025-01-17 16:14:52 +02:00
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`
 2025-01-17 16:11:13 +02:00
Bananymous 03b5c8e76e Kernel: Fix disk caching when `readonly` is specified 2025-01-16 16:16:38 +02:00
Bananymous 609067cefa Kernel: Cleanup internal CPUID functions declarations 2025-01-14 22:57:44 +02:00
Bananymous 9d497ad311 Kernel: Cleanup interrupt stub definitions 2025-01-14 22:55:06 +02:00
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
 2025-01-14 22:50:46 +02:00
Bananymous b129bab81a Kernel: Make mem* and str* functions weak symbols 2025-01-14 19:08:03 +02:00
Bananymous d189f00f38 Kernel: Null terminate tmpfs directory entries 2025-01-12 16:03:09 +02:00
Bananymous a5cf92b2ff Kernel: Use uint64_t instead of size_t for AML node conversion 
This allows 32 bit to compile again :)
 2024-12-30 06:27:49 +02:00
Bananymous 69137cddab Kernel: Implement TIOCSWINSZ for pseudo terminals 
I have no idea how I had forgotten this
 2024-12-21 03:22:48 +02:00
Bananymous d7b4f54983 Kernel: Check Control Method Battery _STA bit 4 
This bit indicates wheter the battery is actually present.

Bananymous 00b0dcd306 Kernel: Reorder ACPI initialization method calls 2024-12-19 02:35:09 +02:00
Bananymous 53c356a940 Kernel: Implement AML MatchOp 2024-12-18 19:26:19 +02:00
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 c26e347e91 Kernel: Fix AML FieldUnit conversion and NameString construction 2024-12-18 18:29:04 +02:00
Bananymous 1b94957b07 Kernel: Copy AML NameString base when moving it :) 2024-12-18 18:28:16 +02:00
Bananymous 4e364bd2f6 Kernel: Add support for ACPI Control Method Batteries 
The implementation is kinda weird but it exposes some battery
information to userspace!
 2024-12-18 14:06:32 +02:00
Bananymous b9fe564d78 Kernel: Check for GCC when ignoring Wmaybe-uninitialized 2024-12-18 01:45:36 +02:00
Bananymous 437fa45ca2 Kernel: Add helper to find ACPI devices with EISA id 2024-12-18 01:45:00 +02:00
Bananymous 85e215650c Kernel: Implement AML ToStringOp 2024-12-18 01:44:33 +02:00

Bananymous 2259614640 Kernel: Remove unused function from ACPI namespace 2024-12-18 01:43:04 +02:00
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 46d4e32510 Kenrel: Validate inode open mode on read/write syscalls 2024-12-15 20:49:12 +02:00

Bananymous 12a37500b0 Kernel: Fix triple-fault in vitual tty 
This was happening when printing non-utf8 data while having virtual tty
as the debug console.
 2024-12-09 03:35:51 +02:00
Bananymous 2d0690ae2d Kernel: Cleanup most of syscalls dealing with files 2024-12-07 05:33:04 +02:00

Bananymous 3bf57e0748 Kernel: Add . and .. entries to /proc/<pid> directories 
This allows to run `cd ..` in one of these directories
 2024-12-07 01:37:40 +02:00
Bananymous 51b6329c86 Kernel: Make backspace \b and delete 0x7F 
This is what `vim` seems to expect and imo makes way more sense.
 2024-12-05 17:34:37 +02:00
Bananymous 72d9e4c1e7 Kernel: Remove accidental debug prints from fcntl syscall 2024-12-05 17:34:32 +02:00
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.
 2024-12-03 21:54:27 +02:00
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.
 2024-12-03 16:17:34 +02:00
Bananymous 2dec3a6c95 Kernel: Add some sanity checks for existanse of threads 2024-12-03 16:16:50 +02:00

Bananymous 0fab7ad63b Kernel: Fix SYS_FCNTL command handling :) 
I had misunderstood how these work
 2024-12-03 16:12:26 +02:00
Bananymous e6a2f55a59 Kernel: Closing file backed mmap wont expand the file size 2024-12-03 16:12:26 +02:00
Bananymous 67e9ca56ac Kernel: Create /dev/urandom -> /dev/random symlink 
Most software uses urandom instead of random so this allows it work
normally.
 2024-12-03 16:12:26 +02:00
Bananymous 713daf6cd3 Kernel/LibC: Add support for creating hardlinks 2024-12-03 16:12:26 +02:00
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
 2024-12-02 20:13:38 +02:00
