29 hourskernel/amd64: Set up seperate syscall stackIan Moffett
It is a good idea to have a completely different stack during syscalls. This commit implements a TSS IST entry for syscalls. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
32 hourskernel: Sort out switch MI/MD switch logicIan Moffett
Certain operations dealing with context switches are better off being implemented as machine dependent routines which allows us to be flexible with what we can do, as well as the extra benefit of requiring less workarounds to keep things MI. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: dev: Add /dev/randomAlex Funo
Introduce a prototype cryptographically secure (?) random number generator. The RNG uses ChaCha20 seeded with a SipHash-processed entropy pool. Entropy is collected only at read time and is mixed into the internal pool before each ChaCha20 reseed. The design is still experimental.

- Implement nvme_get_logpage() routine - Add SMART data structure - Implement basic controller + namespace temperature detection Signed-off-by: Ian Moffett <ian@osmora.org>
11 dayskernel: cons: Introduce /ctl/console/attrIan Moffett
In a lot of existing systems, ANSI escape sequences are used to control console attributes such as cursor position, style, etc. However, too many sequences for too many things are implemented at once. If a program has neglected to properly sanitize input coming in (e.g., from a network). Stray sequences may be injected into the receiving console. One may disable the ANSI state machine using the 'ansi_esc' bit within /ctl/console/feat, completely eradicating such issues, while being able to still control various console attributes through /ctl/console/attr. This commit also keeps the builtin ANSI escape sequence parser as simple as possible. Signed-off-by: Ian Moffett <ian@osmora.org>
13 dayskernel/amd64: Add support for coredumpsIan Moffett
To make debugging userland program crashes easier, this commit introduces coredumps that store the last known process state into a temporary /tmp/core.X file (where X is the PID of the faulting process). Signed-off-by: Ian Moffett <ian@osmora.org>
13 dayskernel: lib: Add CRC32 supportIan Moffett
- Add support for 32-bit cyclic redundancy checks Signed-off-by: Ian Moffett <ian@osmora.org>
13 dayskernel/amd64: cpu: Support SMEPIan Moffett
Some CPUs support Supervisor Memory Execution Protection that prevent ring 3 code from being executed in a ring 0 context. Enable this on CPUs that support it. Signed-off-by: Ian Moffett <ian@osmora.org>
13 dayskernel/amd64: Add 'feat' field in cpu_infoIan Moffett
Keep track of per-cpu features by using a 'feat' field which contains the results of various CPUIDs. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-03kernel: Ensure mutually exclusive console accessIan Moffett
If multiple processes try to write to the console, a race condition of sorts may occur. Similarly, if multiple processes try to read from the console and contend with the console input buffer. One process may steal keys from the other. Prevent this by implementing a mutex within the console descriptor. Each time a process reads or writes the console, it attaches itself. Any other processes attempting to read or write the console while another is attached will be yielded to the scheduler until the resource is free. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-03kernel: devfs: Add block device stat mechanismIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-03kernel: synch: Add mutual exclusion locksIan Moffett
Add mutex locks, these differ from spinlocks as they are named and also yield to the scheduler instead of just spinning if the lock is acquired. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-03kernel: driver: Implement driver blacklistIan Moffett
Sometimes one may not want *all* of the drivers to start up during system boot. The driver blacklist allows one to mark a driver to be ignored during startup. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-03kernel: driver: Assign names to all driversIan Moffett
Assign a name to each driver through the DRIVER_EXPORT() or DRIVER_DEFER() macros. This can be used for blacklisting driver startups. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-03kernel/aarch64: Add 'board_info' structureIan Moffett
Introduce a 'board_info' structure as well as an md_get_board() routine to get information about the host Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-02kernel: console: Add 'show_curs' feat flagIan Moffett

2025-07-01kernel: console: Introduce cons_screen featuresIan Moffett
Introduce a 'feat' field in the cons_screen structure to allow certain console features to be turned on or off. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-01kernel: tmpfs: Store the *real* size in a nodeIan Moffett
The 'len' field within the tmpfs node stores the buffer length which is relative to the tmpfs block size. Introduce a real size which returns the amount of data actually present within those buffers. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-07-01kernel: vnode: Only include vm/*.h ifdef _KERNELIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-06-29kernel: Introduce SYS_inject syscallIan Moffett
The SYS_inject syscall will allow the user to inject Kernel Runtime Quantums (KRQs) into the running kernel. As of now, set paths are not supported and the initial implementation includes a NULL path used to load all deferrable drivers. Previously during kernel startup, all deferrable drivers were loaded automatically. This commit makes it so that they are only loaded when sys_inject() is called with a NULL path. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-06-28usr: libc: Store auxiliary vector tag/value pairsIan Moffett
This commit introduces the global libc '__libc_auxv' containing auxiliary vector entries as per the System V Application Binary Interface Signed-off-by: Ian Moffett <ian@osmora.org>
