Bananymous 11310e7615 Kernel: Don't manually clear xHCI interrupt flag if using MSI 2025-02-10 22:58:14 +02:00
Bananymous 22b32a0fe5 Kernel: Expose PCI interrupt mechanism from PCIDevice 2025-02-10 22:57:25 +02:00
Bananymous ad143c184f Kernel: Add basic support for USB hubs 
This is still buggy and some hubs lead to usb transaction errors. I'll
have to debug this but this shouldn't prevent any already working device
from working
 2025-02-10 22:56:25 +02:00
Bananymous 803a4cd163 Kernel: Don't enable ACPI devices when ACPI is disabled 
This really didn't make any sense. There are no ACPI device to be
initialized when AML is not parsed :D
 2025-02-07 21:35:25 +02:00
Bananymous 267fdf9fa1 Kernel: Remove storage devices after unplugging them 2025-02-07 18:04:54 +02:00
Bananymous 26d2a4420e Kernel: Don't limit xHCI TRB transfer length to max packet size 
This made no sense and just used a ton of TRBs.

This patch also fixes some incorrectly set flags in data/status stage
TRBs.
 2025-02-06 23:18:14 +02:00
Bananymous c623ad7da0 Kernel: Use correct USB endpoint field to determine interval 
I was using the wrong endpoint descriptor field which caused intervals
to be messed up.
 2025-02-06 23:18:14 +02:00
Bananymous 7de689055c Kernel: Pass xHCI device information in structs 
This makes code more readable and extendable
 2025-02-06 23:18:14 +02:00
Bananymous 63b15a8855 Kernel: Rename USB initialize_endpoint -> configure_endpoint 
This makes more sense as the USB command is CONFIGURE_ENDPOINT

Also configure_endpoint can be called multiple times on the same
endpoint. There was no reason to limit this to only one call.
 2025-02-06 22:10:00 +02:00
Bananymous a2a7302964 Kernel: Make sure USB class driver is deinitialized before xhci device 2025-02-06 22:00:26 +02:00
Bananymous 6a5367dbe3 Kernel: Don't initialize USB alternate interfaces 2025-02-06 21:43:15 +02:00
Bananymous 6768a18475 Kernel: Don't parse xHCI custom slot_types 
xHCI spec mandates that slot_type for USB protocol is 0.
 2025-02-06 21:41:44 +02:00
Bananymous 242ed4a3c2 Kernel: Remove support for custom xHCI speed_ids 
This gets really weird with hubs and I don't think even linux handles
them.
 2025-02-06 21:38:30 +02:00
Bananymous f9b70d1b5b Kernel: Don't enter infinite loop on unexpected serial behaviour 2025-02-06 20:59:17 +02:00
Bananymous faa5252191 Kernel: Fix TTY ANSI CSI m and prevent crash :) 2025-02-06 20:58:03 +02:00
Bananymous 4212f48d7a bootloader: Cleanup memcpy and memset 
There isn't really any reason to do 32 bit moves
 2025-02-06 20:56:35 +02:00
Bananymous b30a79c7fe Kernel: Temporary hack to "fix" munmap 
My current munmap implementation does not support partial unmaps and
GCC relies on this behaviour. This patch removes unmapping if the
address and len does not fully contain the mmap region.
 2025-02-01 22:25:22 +02:00
Bananymous 22374ac8f7 ports: Add make port 2025-01-28 22:50:11 +02:00
Bananymous 17014bb8de LibC: Fix strndup 
I did not null terminate short strndup copies :D
 2025-01-28 22:40:06 +02:00
Bananymous d1c3d3d5aa Kernel: Fix ANSI CSI L 
With my new memcpy implementation this crashed. I have no idea how this
was not crashing before :D
 2025-01-28 18:41:53 +02:00
Bananymous 7fedd94cc5 ln: Don't require link target to exist for symlinks 2025-01-28 17:46:36 +02:00
Bananymous 48eca3d031 LibC: Make libc usable with tcc 
tcc does not provide its own stdint.h but defines everything in
stddef.h. Also tcc does not support [[noreturn]] attribute syntax.
 2025-01-28 17:27:41 +02:00
Bananymous 21d3cf91a0 LibC: Implement some missing signal.h functions 2025-01-28 17:27:41 +02:00
Bananymous 5938cc4086 Kernel: Support pselect sigmask 2025-01-28 17:17:59 +02:00
Bananymous 7c57d736c6 Kernel/LibC: Fix dirent functions 
dirent functions used to fail if a directory contained more than 128
files :D
 2025-01-28 17:15:11 +02:00
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
 2025-01-28 17:11:21 +02:00
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
 2025-01-28 17:06:35 +02:00
Bananymous efb577769e ports: Add nasm port 2025-01-25 23:10:04 +02:00
Bananymous 8c569ac7bf 2500th COMMIT: ports: Add gcc port 
I've had this laying around locally for a while. binutils was not
working so I didn't feel like this was worth pushing. My new stdio FILE
buffering rewrite fixed binutils and now gcc actually works!
 2025-01-25 18:40:16 +02:00
Bananymous a84fb57e32 ports: Add binutils port 2025-01-25 18:40:16 +02:00

Bananymous cbcb9f9044 Kernel: Warn on unsupport clock_gettime clock_ids 2025-01-25 17:31:17 +02:00
Bananymous 60bffb5f49 LibC: Implement clock in terms of clock_gettime 
This allows clock to "just work" after I update clock_gettime to support
CLOCK_PROCESS_CPUTIME_ID.
 2025-01-24 19:58:44 +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 c6cd185cb5 DynamicLoader: Fix copy relocations 
Weak symbols are now actually resolved to the same strong symbol between
shared objects and copy relocations now work!
 2025-01-24 19:23:33 +02:00
Bananymous 58cdcf754c ports: Update curl port 
This patch updates curl to version 8.11.1 and adds support for dynamic
libraries
 2025-01-24 19:23:33 +02:00
Bananymous d969f5df7b ports: Add zstd port 2025-01-24 19:23:33 +02:00

Bananymous 15021b442c LibC: Fix memchr and memcmp assembly implementations 
These functions did not work with size 0 :D
 2025-01-23 21:55:26 +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 766b8cd62e LibC: Fix stdio FILE operations 
Mixing read/write/ungetc was broken. This mostly fixes everything. There
might still be some problems that have to be fixed
 2025-01-16 14:57:58 +02:00
Bananymous 609067cefa Kernel: Cleanup internal CPUID functions declarations 2025-01-14 22:57:44 +02:00

Bananymous 72059a9441 LibC: Redefine SEEK_* macros to match common systems 
some ports written in assembly seem to depend on this
 2025-01-14 22:52:13 +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 14c70c5cc8 LibC: Make mem* and str* functions weak symbols 
This allows adding architecture dependent implementations while still
providing an general implementation
 2025-01-14 18:36:54 +02:00
Bananymous d62a67502e LibC: Remove global -fno-tree-loop-distribute-patterns flag 
This is only really needed for string.cpp where mem* and str* functions
are defined
 2025-01-14 18:35:33 +02:00
Bananymous 4b2c303873 LibC: Add weak_alias header that defines a weak_alias macro 2025-01-14 18:33:57 +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 8c45249c06 LibC: Remove stdint.h as toolchain provides one 
I have no idea why i even had this written, it was just containing
compiler macros
 2024-12-30 06:26:17 +02:00
Bananymous 55c8a15983 aoc2024: Implement day25 solution 
This was a nice AOC season. First time I fully completed it! I may still
optimize my solutions as some of them are a bit slow...
 2024-12-25 18:13:57 +02:00
Bananymous 3607e2e759 aoc2024: Implement day24 solution 
This is kinda weird and specific to my input but it works xD
 2024-12-25 18:13:20 +02:00
Bananymous d035068982 aoc2024: Implement day23 solution 
I'm not proud of my implementation to last 2 days, but they work in a
reasonable time. I might optimize them later...

Problem is largely with my hash structures. Preallocating a lot of
elements before running day22 makes it run in less than half of the
current time.
 2024-12-23 21:20:47 +02:00
Bananymous af8156f310 aoc2024: Implement day22 solution 2024-12-23 01:47:27 +02:00
Bananymous 47b995a2a3 aoc2024: Implement day21 solution 2024-12-22 21:39:28 +02:00
Bananymous 6f8f99f42c Terminal: Set terminal size with TIOCSWINSZ when starting 
This actually fixes the very broken vim port
 2024-12-21 03:23:21 +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 9caa3030ea aoc2024: Implement day20 solution 2024-12-20 21:31:10 +02:00

Bananymous d7b4f54983 Kernel: Check Control Method Battery _STA bit 4 
This bit indicates wheter the battery is actually present.
 2024-12-19 02:35:09 +02:00
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 a7f3351c0e TaskBar: Prevent possible division by zero 
If battery reports its full capacity as zero, battery percentage
calculation did a division by zero crashing the TaskBar :)
 2024-12-18 18:36:26 +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
 2024-12-18 18:30:45 +02:00
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 2e39668605 aoc2024: Implement day18 solution 2024-12-18 14:06:32 +02:00
Bananymous 0642c569b4 TaskBar: Show battery percentage if available 2024-12-18 14:06:32 +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 7eb186dad4 Kernel: Add to_sv() helper for AML String 2024-12-18 01:43:46 +02:00
Bananymous 2259614640 Kernel: Remove unused function from ACPI namespace 2024-12-18 01:43:04 +02:00
Bananymous a584e1a4ec aoc2024: Implement day17 solution 2024-12-17 23:30:37 +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.
 2024-12-17 03:36:33 +02:00
Bananymous 463bb72d24 aoc2024: Implement day16 solution 2024-12-16 17:23:08 +02:00

Bananymous 3e36834751 aoc2024: Implement day10 solution 2024-12-10 17:26:39 +02:00
Bananymous 581caff638 BuildSystem: Install base sysroot only once 
Base sysroot is not only installed when creating the syroot directory
for the first time. To get it installed again, you have to either delete
the old sysroot diretory or run clean target

This makes it so its actually possible to edit files specified in the
base sysroot without random hacks.
 2024-12-10 16:44:59 +02:00
Bananymous 8b612ba547 aoc2024: Implement day9 solution 
part2 is kinda unoptimized, it should not use expanded input, but I did
not feel like rewriting my parsing code :)
 2024-12-09 16:20:21 +02:00
Bananymous 90820f24a4 BAN: Make HashMap::{insert,emplace}{,_or_assign} return an iterator 
This reduces the number of lookups done into the hash map :)
