43 hoursusr.bin: Add 'readcore' programIan Moffett
This commit introduces a new program called 'readcore'. This program allows a user to debug crashed programs by passing in the path of a coredump file. Signed-off-by: Ian Moffett <ian@osmora.org>
43 hourskernel/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>
43 hourskernel: lib: Add CRC32 supportIan Moffett
- Add support for 32-bit cyclic redundancy checks Signed-off-by: Ian Moffett <ian@osmora.org>

Allow the user to configure if SMEP would be enabled for their build of the Hyra AMD64 port Signed-off-by: Ian Moffett <ian@osmora.org>
46 hourskernel/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>
46 hourskernel/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>
47 hourskernel: tmpfs: Prevent read() on empty filesIan Moffett
If we have never written to a tmpfs file, the buffer for it will have never been allocated and that would lead to NULL pointer issues such as system-wide crashes. Return zero bytes read if nothing was ever written. Signed-off-by: Ian Moffett <ian@osmora.org>
47 hourskernel: tmpfs: Do not NULL np->data during reclaimIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskernel: 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>

3 dayskernel: synch: Use md_pause() in spinwait loopIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskernel: 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>

3 dayskernel: driver: Implement driver blacklistIan Moffett

3 dayskernel: 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>
4 dayskernel/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>

Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskernel: ctlfs: Add ctlfs_get_ops() to fetch ctlopsIan Moffett
This commit cleans up the read routine by creating a helper that fetches common fields from the ctlfs entry while checking things such as its magic number. Signed-off-by: Ian Moffett <ian@osmora.org>
5 dayskernel: 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>
7 dayskernel: 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.
