4 daysusr.bin: osh: Allow execution of direct pathsIan Moffett
This commit allows the end-user to supply a path (e.g., /usr/bin/mrow) straight to the shell to be interpreted as a binary executable path. Signed-off-by: Ian Moffett <ian@osmora.org>
4 daysusr: Add 'echo' program to replace osh builtinIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
4 daysusr.bin: osh: Rename 'i' to 'buf_i'Ian Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
4 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. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>

6 dayskernel/amd64: mp: Give each core an idle threadIan Moffett
Having the same amount of idle threads per core allow the CPU to always have a thread assigned to one of its cores even when there are currently no other threads for it to take. Signed-off-by: Ian Moffett <ian@osmora.org>
6 dayskernel: descrip: Validate operations against sealIan Moffett
Ensure file I/O operations match the seal that their respective file descriptors were set with. Signed-off-by: Ian Moffett <ian@osmora.org>

Add support for the O_CREAT flag which allows file creation upon an open() call. Signed-off-by: Ian Moffett <ian@osmora.org>
7 dayskernel: namei: Add NAMEI_WANTPARENT flagIan Moffett
In some lookup cases, we may only be interested in the parent component. For example, the parent of "/foo/bar/mrow" is "/foo/bar/". The NAMEI_WANTPARENT asks namei to only look for the parent rather than the full path. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: Add "starting init" message for verbosityIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>

8 dayskernel/amd64: mc1468xx: Implement date settingIan Moffett
Implement logic to update the date returned by the MC1468XX/RTC chip. This can be used to later implement some sort of time synchronization protocol or manual setting of the date. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel/amd64: mc1468xx: Add 2000 to the yearIan Moffett
The year register of the RTC does not keep track of the century so default to 2000 until we figure out the non-standard century register. Signed-off-by: Ian Moffett <ian@osmora.org>
