26 hourskernel: accnt: Keep track of per-cpu statsIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
26 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>
27 hourskernel: Move 'g_nthreads' to kern_accnt.cIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
27 hourskernel: Add initial accounting logicIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
27 hourskernel: proc: Decrement proc count on exitIan Moffett
Previously, our process counter was monotonic (wuh oh!). We want to be sure that it decrements when a process exits. - Rename nthreads to g_nthreads as a global - Atomically increment on enter and decrement on exit Signed-off-by: Ian Moffett <ian@osmora.org>
28 hourssys: atomic: Add 64-bit operationsIan Moffett

Allow finer control over which LEDs to toggle and how they should be toggled. Signed-off-by: Ian Moffett <ian@osmora.org>

Refer to share/docs/hw/et131x.txt Signed-off-by: Ian Moffett <ian@osmora.org>
4 dayskernel/amd64: Track interrupt countIan Moffett
Keep track of how many times an interrupt fires, this can be used for interrupt statistics later on. Signed-off-by: Ian Moffett <ian@osmora.org>
4 dayskernel/amd64: Get CPU family + modelIan Moffett
The CPU family ID and model number are sometimes useful in order to detect the presence of certain CPU features as well as detecting CPU specific quirks. Signed-off-by: Ian Moffett <ian@osmora.org>

5 dayskernel/amd64: Return NULL if IA32_GS_BASE is unsetIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskernel: Avoid using kprintf() during panicIan Moffett
Avoid using kprintf() during a system panic event as it relies on internal locking that may hang the system preventing diagnostics from being logged Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskernel: Make panic screen configurableIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
7 dayskernel/sched: Undo sched_yield() changesIan Moffett
- Keep old sched_yield() logic as newer logic caused issues on QEMU - TODO: Actually fix and test Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: exit: Clear out file descriptors on reapIan Moffett
Ensure all file descriptors are freed and their respective vnodes released. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: sched: Greatly simplify yield logicIan Moffett
The purpose of yielding to the scheduler is to tell it you want to preempt early in order to not starve processes while waiting for I/O. We can trigger the timer earlier on for stability as a ~10 usec delay should not be too terrible. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: ucred: Add SYS_getuidIan Moffett
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.

9 dayskernel: cons: Use glyph relative pos in cons attrIan Moffett
- Make curs_col/curs_row reference console_attr.cursor_x/cursor_y - Console cursor x/y attributes reflect x/y multiplied by glyph dimensions Signed-off-by: Ian Moffett <ian@osmora.org>

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>
