apio	6443ec77f8	kernel/ATA: Add support for regular ATA drives (non-ATAPI) ... Don't know why this took so long to figure out, I just had to pass the right value to select().	2024-03-29 12:11:39 +01:00
apio	fc37634a18	kernel: Add much-needed support for extended keyboard scancodes	2024-03-06 20:33:54 +01:00
apio	17b44a8ce6	kernel: Reenable stack tracing in kernel-mode exceptions ... Stack tracing in user-mode exceptions was moved to when a signal kills the process, but this isn't done for kernel-mode exceptions so there was no stack trace anymore.	2024-01-05 22:14:31 +01:00

apio	36fad85396	kernel+init+preinit+wind: Remove the kernel TTY and support only userspace terminals ... Still allow printing text to the console, but without text input or ANSI escape fancy stuff.	2023-09-21 19:31:54 +02:00
apio	4af337e92d	kernel: Improve the mutex system	2023-09-20 07:05:33 +02:00

apio	54cc80f649	kernel/ATA: Replace a manually allocated buffer with Buffer ... This also lets us keep it empty unless it is used, in which case we resize it (if it wasn't already resized).	2023-08-16 09:15:00 +02:00
apio	ed8b210639	kernel: Detect some other cases of non-DMA support	2023-08-08 18:23:13 +02:00
apio	f45734c61d	kernel/ATA: Stop storing ATA::Drive in a separate shared pointer	2023-08-07 19:22:57 +02:00
apio	b4527786d4	kernel/MMU: Don't copy pages on clone and allow manipulating other page directories	2023-08-02 22:17:32 +02:00
apio	4794d0dfef	kernel: Add a keyboard device for graphical session	2023-08-02 17:20:13 +02:00
apio	df77fc8de8	libluna: Remove make_array() and destroy_array() ... Placement new on arrays is a bit unreliable and could cause out-of-bounds data accesses.	2023-08-02 14:47:58 +02:00
apio	e8f3dd4cf9	kernel: Add a PS/2 mouse driver	2023-08-02 11:55:45 +02:00

apio	4ed7ec5e93	libluna: Store SharedPtr's ref count in the object itself	2023-07-30 11:32:46 +02:00
apio	11df5a2ec3	kernel: Use pid_t internally for process IDs ... This removes a bunch of casts between pid_t and u64, and makes more sense since pid_t is literally the data type for process IDs.	2023-07-26 21:32:00 +02:00
apio	5aad7d3154	kernel/x86_64: Fail on invalid interrupts instead of calling FIXME_UNHANDLED_INTERRUPT ... A FIXME is something that should be changed later, this is a check for something that should never happen.	2023-07-25 18:23:33 +02:00
apio	105ed79f8f	kernel: Reenable userspace stack tracing, but hidden behind a config flag ... Sometimes this is needed for userspace program debugging (such as ports), but sometimes it can crash, so we leave it off by default.	2023-07-25 17:02:09 +02:00
apio	36a74fd8d6	kernel/x86_64: Provide an alternate kernel stack for exceptions ... This avoids stack-related triple faults, hopefully. Closes #33.	2023-07-21 15:14:52 +02:00
apio	cd6bf745a7	tests+kernel+init: Run tests automatically in a headless way	2023-07-21 14:09:37 +02:00
apio	f9003d7a58	kernel: Mask away unsafe bits in rflags when restoring state after a signal	2023-07-15 11:54:48 +02:00
apio	89786d8be2	kernel: Save/restore the SSE/FPU state when executing signal handlers	2023-07-15 11:53:50 +02:00
apio	de6fe7f7c2	kernel+libc+sh: Make the TTY device actually follow termios rules ... Like, so much more termios compatibility!	2023-07-13 20:33:20 +02:00
apio	f629e17ff4	kernel/x86_64: Only show kernel addresses in backtraces ... This avoids walking off into userspace memory where we don't know what could happen.	2023-07-12 16:04:45 +02:00
apio	d27ffce5db	kernel: Move the signal handling logic to after a syscall sets its return value ... When a signal was caught after a syscall, it was doing so without preserving the return value of the syscall.	2023-07-12 13:34:30 +02:00
apio	86d14e0d0e	kernel+libc: Add the SA_NODEFER and SA_RESETHAND flags for sigaction()	2023-07-10 21:54:04 +02:00
apio	015419b8f5	kernel: Generate signals when children exit / when faults occur ... Userspace can now catch segfaults!	2023-07-10 20:49:22 +02:00
apio	15d6aae701	kernel+libc: Implement basic signals	2023-07-10 19:46:57 +02:00
apio	7908c5a63e	kernel/ATA: Do not discard the controller if at least one channel initialized properly ... This was causing problems in VirtualBox.	2023-07-10 13:01:43 +02:00
apio	e9e7b22323	kernel: Separate a thread's page directory into two ... The self directory, and the active directory. The active directory is the one the thread is currently using, and the self directory is the one the thread owns. This lets us keep track of both, which fixes ext2 executables crashing the system.	2023-06-25 20:35:40 +02:00
apio	e60b2a3d2f	kernel: Move thread exit code into a separate common function	2023-06-19 12:33:25 +02:00
apio	7efc3a6ea1	kernel: Show stack traces on page faults + crash the process instead of the whole system on GPFs	2023-06-19 10:45:08 +02:00
apio	7cace9a0d7	kernel: Provide more meaningful panic messages for critical failures	2023-06-17 19:43:25 +02:00
apio	2be4880278	kernel: Name the scoped lock in ATADevice::read() ... Is that supposed to work without a name? Looks like it did!	2023-06-17 09:46:28 +02:00
apio	c2cdb861c9	kernel/ATA: Fix buffer overflow in ATADevice::read() with small sizes and unaligned offsets	2023-06-17 00:48:53 +02:00
apio	27b26f389c	kernel: Lock ATADevice::read_lba() using ATA::Channel's KMutex	2023-06-17 00:22:38 +02:00
apio	32d2e0e6b7	kernel: Remove register_special_device()'s name parameter ... This is now duplicate information that can be queried using device->device_path().	2023-06-16 21:46:51 +02:00
apio	ba46399bbd	kernel/ATA: Remove debug messages	2023-06-16 21:34:36 +02:00
apio	738b218a49	kernel/ATA+MBR: Dynamically generate device names + create devices for MBR partitions	2023-06-16 21:30:50 +02:00
