Bananymous 87ff38664a Kernel/LibC: Add syscall and wrapper for unlink 2023-10-25 21:45:04 +03:00
Bananymous b7007016c0 BAN: Implement Ext2 file unlinking 
Ext2 inodes can now be unlinked from directories and after last
inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem
 2023-10-25 21:43:36 +03:00
Bananymous 3566ddab00 BAN: ByteSpan can be sliced without specified size

This does not support any meaningful command line arguments but
is a good start.

Bananymous 07f8c972b3 Shell: Set get old termios earlier 
I sourced the config file before getting old termios. Sourcing
updated the termios so old_termios was always in non canonical, non
echoing mode.
 2023-10-24 19:10:53 +03:00
Bananymous fc8a000e46 BAN: Fix bug of size of splice after slice() 
I have no idea what was I doing before :D
 2023-10-24 17:23:45 +03:00
Bananymous 6f6ccbfa04 meminfo: fix g++ warning for oob write 
g++ doesn't realize that read can only return -1
 2023-10-24 16:50:21 +03:00
Bananymous c71ac588b2 BuildSystem: Fix bugs in new build system 
I had not tested the new build system with clean toolchain build
but it seems to work now.
 2023-10-24 16:48:46 +03:00
Bananymous 2d0da93ac4 Kernel: Add timeout to ACHI commands 
ACHI commands can now fail from timeouts.
 2023-10-24 11:56:25 +03:00
Bananymous fb801044ec BuildSystem: Match README.md with the new buildsystem 2023-10-24 11:56:00 +03:00
Bananymous ce87e0a605 BuildSystem: Rewrite whole build system structure 
Now you have to use script/build.sh for building and running banan-os
 2023-10-24 11:56:00 +03:00
Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan 
This allows us to not work with raw pointers and use sized containers
for reading and writing.
 2023-10-24 11:56:00 +03:00
Bananymous 71cad2fc38 BAN: Implement ByteSpan 
This is a span over exisiting containers/data types. I'm not too
happy with the constructors and assignment operators, but they will
work for now
 2023-10-20 04:59:29 +03:00
Bananymous 61c7a68f4a BAN: add helper to cast Span<T> to Span<const T> 2023-10-20 04:59:08 +03:00
Bananymous c17cdb39d5 Kernel: Map multiboot2 memory in PageTable initialization 
It cannot be assumed that multiboot data lies between kernel_end
and 2 GiB mark, so I properly allocate virtual address space for it.
 2023-10-17 01:15:08 +03:00
Bananymous 69a39b7077 Kernel: Start using multiboot2 instead of multiboot 
This allows better compatibility with (U)EFI and gives RSDP location
instead of me having to scan ram to find it.
 2023-10-17 01:06:24 +03:00
Bananymous 19696bdad3 Kernel: TTY doesn't panic if it doesn't find input device 2023-10-16 16:58:39 +03:00
Bananymous 00dd7d85ce Kernel: Fix device identification with all bits as ones 
If device identification sends all ones, don't initialize the device.
 2023-10-16 16:57:07 +03:00
Bananymous 0c88c74b76 Kernel: ATABuses are but to compatibility mode if possible 
I don't support native mode ata bus (irq sharing) so ata buses are
but to compatibility mode if possible.
 2023-10-16 16:56:12 +03:00
Bananymous c4a640bcb6 Kernel: Fix ATADevice naming 
ATADevice now stores its name instead of using static buffer. Old
static buffer was changing on every name query. I just hadn't noticed
since virtual machine disks were always sda.
 2023-10-16 16:52:15 +03:00
Bananymous 0fdf8b6f68 Kernel: Fix PCI bugs 
IO BarRegion used vaddr instead of the correct paddr. Add API for
memory region iobase query.
 2023-10-16 16:50:49 +03:00
Bananymous 37bc52988c Kernel: Don't require framebuffer 
Initializes virtual tty only if framebuffer is initialized
 2023-10-16 01:44:54 +03:00
Bananymous 1312a9dad2 Kernel: PCI checks if ethernet device is E1000 before initialization 
I used to treat all ethernet deivices as E1000 but now it is actually
verified before initialization
 2023-10-16 01:44:54 +03:00
Bananymous 73b9c28457 Kernel: PCIDevice stores its vendor id and device id 2023-10-16 01:44:54 +03:00
Bananymous 29db8d0d40 BuildSystem: add cmake variable UEFI_BOOT 
If this variable is defined in cmake, image will be build with esp
and booted with uefi.
 2023-10-16 01:44:54 +03:00
Bananymous 5bf0f9742a Toolchain: Build grub with efi capabilities 2023-10-16 01:37:12 +03:00
Bananymous fc5bfa2cb3 Kernel: Clear TTY when setting as current 
Actually this should replace from old buffer, but this works
for now.
 2023-10-13 17:20:26 +03:00
Bananymous f7e38ccfe4 Kernel: Don't crash if header type != 0 in bar region creation 
Also remove spammy debug printing
 2023-10-13 16:32:32 +03:00
Bananymous 128202a55a Kernel: Cleanup GDT code 2023-10-13 16:18:22 +03:00
Bananymous 89d74a9088 Kernel: Separate scheduler execution and stack loading 
Not sure if this is actually needed, but this allows actual
executing function to be in clean environment
 2023-10-13 16:17:27 +03:00
Bananymous 63f64619bc Kernel: add NEVER_INLINE and make Interruptable not constructable 2023-10-13 16:17:27 +03:00
Bananymous 518fd3fad0 Kernel: Add 16 more irq handlers 
IDT will now panic if trying to assing handler for non supported
irq.
 2023-10-13 16:17:27 +03:00
Bananymous 74b77ba2ac Kernel: Debug temporary debug print just to beginning when full 2023-10-13 12:43:52 +03:00
Bananymous 888e44ce0b Kernel: Allow getting ACPI headers with same signature 2023-10-13 11:24:21 +03:00
Bananymous b3b8376cca Kernel: Fix PhysicalRange mapping size 2023-10-13 03:45:01 +03:00
Bananymous 9c143d18b9 Kernel: Add temporary terminal output before controlling terminal 
Starting work on getting this boot on real hardware.
 2023-10-13 03:31:36 +03:00
Bananymous 9a6cc0dc2d Kernel: Check whether ELF address space can be loaded 
Before reserving address space in SYS_EXEC verify that ELF address
space is actually loadable. For example when trying to execute the
kernel binary in userspace, binarys address space would overlap with
current kernel address space. Now kernel won't crash anymore and
will just send SIGKILL to the process calling exec*().
 2023-10-12 22:59:36 +03:00
Bananymous 8c792f9c6d Shell: Fix parsing $ with unknown character 2023-10-12 22:24:27 +03:00
Bananymous adc5ff9e99 Kernel: Implement AHCI driver 
SATA drives can now be used with banan-os. This allows much faster
disk access (writing 10 MiB from 30s to 1.5s). This can definitely
be optimized but the main slow down is probably the whole disk
structure in the os.

AHCI drive is now the default when running qemu.
 2023-10-12 21:53:48 +03:00
Bananymous bde9ff9319 Kernel: Generalize ATA device and cleanup code 2023-10-12 21:35:25 +03:00
Bananymous 75fdf4c3c6 Kernel: Add Timer::ns_since_boot() 2023-10-12 21:16:39 +03:00
