Justin C. Miller	d4283731e4	[kernel] Add syscall helpers ... Added the syscalls/helpers.h file to templatize common kobject syscall operations. Also moved most syscall implementations to using process::current() and thread::current() instead of asking the scheduler.	2020-09-23 00:22:15 -07:00
Justin C. Miller	724b846ee4	[kernel] Make channels stream based ... Multiple changes regarding channels. Mainly channels are now stream based and can handle partial reads or writes. Channels now use the kernel buffers area with the related buffer_cache. Added a fake stdout stream channel and kernel task to read its contents to the screen in preparation for handing channels as stdin/stdout to processes.	2020-08-30 18:04:19 -07:00
Justin C. Miller	d3e9d92466	[kernel] Add channel objects ... Add the channel object for sending messages between threads. Currently no good of passing channels to other threads, but global variables in a single process work. Currently channels are slow and do double copies, need to refine more.
