27 hourskernel/amd64: i8042: Use DMI for quirk checkingIan Moffett
On certain embedded controllers (ECs) like the EC present on the Thinkpad T420s, writes to the i8042 controller configuration byte are not very liked by the EC internal logic and thus result in them asserting an NMI as a certain host bus error. To workaround this, Hyra falls back to polling on these specific devices. Previously, Hyra did not have DMI/SMBIOS capabilities and therefore had to rely on assuming *all* Lenovo devices were "hostile". As of now since we are capable grabbing the product version from DMI, we can target specific devices like the T420s and this commit provides that logic. This commit additionally implements logic to enable interrupts on PS/2 port 0 (aka the keyboard). Signed-off-by: Ian Moffett <ian@osmora.org>
27 hourskernel/amd64: Throw away any pre-kernel huge pagesIan Moffett
Before the Hyra kernel starts up, the Limine bootloader creates a mapping of the first 4 GiB of memory (identity mapped for base revisions of zero and mapped to the HDDM on higher base revisions). However, it usually will create a huge mapping over this which would be problematic during remaps of device MMIO base addresses as they typically reside at the 4 GiB region of RAM and as of this commit, huge pages are not a supported feature of the Hyra AMD64 pmap layer.

27 hourskernel/amd64: Only use USER_DS in md_td_kick()Ian Moffett
The function md_td_kick() is only used for user threads and there is no need reference any kernel segments. Furthermore, the previous code would introduce a bug where rpl would always be 0. Signed-off-by: Ian Moffett <ian@osmora.org>

3 daysusr.bin: osh: Implement shell script parsingIan Moffett
Previously, OSH was only capable of interpreting commands that came directly from the console. This commit allows calling /usr/bin/osh while passing a path to a script to be parsed and interpreted. This commit additionally adds a `command_match()` routine to simplify the matching of commands. On top of this, cmd_run() now also takes a `wait` argument that allows the caller to specify whether not to daemonize the spawned process or wait on its execution to finish.

3 dayskernel: exit: Only kill leaf if not exitingIan Moffett
During an exit(), the parent needs to kill all of the child processes that depend on it. However, there might be an occurrence where one or more is already exiting and trying to kill such processes would be problematic and may result in issues like double frees. This commit ensures that the exiting parent only kills child processes that aren't already exiting themselves. Signed-off-by: Ian Moffett <ian@osmora.org>

5 dayskernel: ctlfs: Do not reclaim ctlfs entriesIan Moffett
There will likely be multiple times the reference count of a ctlfs entry will hit zero. Several programs may open and close a ctlfs node more than once and as these are hardwired kernel objects, they must always stay present. At the most we may set the vp->data field to NULL, indicating that it is currently unused. Signed-off-by: Ian Moffett <ian@osmora.org>
