Bananymous 091c5b6a66 BAN: Implement Ext2 file unlinking

inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem

Bananymous 1e2c2fb973 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.

g++ doesn't realize that read can only return -1
 2023-10-24 16:50:21 +03:00
Bananymous e8d20bc653 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 00ee86920a Kernel: Add timeout to ACHI commands 
ACHI commands can now fail from timeouts.
 2023-10-24 11:56:25 +03:00

Bananymous df69612bb1 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 5bfeb9f3ca 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 db5c24b2a5 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 781c950af6 BAN: add helper to cast Span<T> to Span<const T> 2023-10-20 04:59:08 +03:00
Bananymous e2e5c31d54 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 be3efb0b92 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 792bb2df1c Kernel: TTY doesn't panic if it doesn't find input device 2023-10-16 16:58:39 +03:00
Bananymous e01928d186 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 48980b56ab 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 b767317a7a 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 6f8fce94a0 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 31aa157201 Kernel: Don't require framebuffer 
Initializes virtual tty only if framebuffer is initialized
 2023-10-16 01:44:54 +03:00
Bananymous 5977341610 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 76f17bd569 Kernel: PCIDevice stores its vendor id and device id 2023-10-16 01:44:54 +03:00
Bananymous 6b1b3d333c BuildSystem: add cmake variable UEFI_BOOT 
If this variable is defined in cmake, image will be build with esp
and booted with uefi.

Bananymous cb65be3e33 Toolchain: Build grub with efi capabilities 2023-10-16 01:37:12 +03:00
Bananymous dafc016293 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 c7b6fc950a 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 45a6783c3d Kernel: Cleanup GDT code 2023-10-13 16:18:22 +03:00
Bananymous 6b180da4e8 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 cf4f5f64a5 Kernel: add NEVER_INLINE and make Interruptable not constructable 2023-10-13 16:17:27 +03:00
Bananymous 5630f64175 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 1d61bccfc3 Kernel: Debug temporary debug print just to beginning when full 2023-10-13 12:43:52 +03:00
Bananymous f842a9255f Kernel: Allow getting ACPI headers with same signature 2023-10-13 11:24:21 +03:00
Bananymous 72f3c378dd Kernel: Fix PhysicalRange mapping size 2023-10-13 03:45:01 +03:00
Bananymous 39be6ab099 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 773dcdd3a2 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*().

Bananymous f0820e6f24 Shell: Fix parsing $ with unknown character 2023-10-12 22:24:27 +03:00
Bananymous a2b5e71654 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.
