HOW TO WRITE C CODE FOR RM SCHEDULING PATCH
I fully expect running a system with this EXACT patch will cause it to crash - so use at your own risk :-) diff -git a/include/linux/sched.h b/include/linux/sched.h Right now, I've only compiled the kernel. Below is the patch that will add a new scheduler to the 2.6.34 vanilla kernel. I've figured out the answer to my question, so I thought I'd add it here. This assumption is the basis for the shortest-seek-time-first (SSTF) algorithm. It seems reasonable to service all the requests close to the current head position before moving the head far away to service other requests.

I'd love to see an answer or a pointer on how to do this a little better (ie, keep CFS, at least for right now).ĮDIT #3: I've answered my own question below, as I think I've figured it out. C program to implement the Disk Scheduling algorithm for Shortest Seek Time First (SSTF), by sched.c now looks like: #ifdef CONFIG_SCHED_BFS I'm looking for a way to add my own scheduler alongside the normal linux schedulers (similar to SCHED_FIFO).ĮDIT #2: The BFS pointer below is a good start, but it still rips CFS out of the kernel. Right now, I'm grepping for SCHED_FIFO, SCHED_RR, and SCHED_NORMAL in the kernel source tree, so really I'm looking for a more insightful way to look at it :-)ĮDIT: As some background, I'm very familiar with the FreeBSD scheduler (and the FreeBSD kernel in general), so I'm not looking for pointers on how to do process/thread level scheduling. In computer science, rate-monotonic scheduling (RMS) is a priority assignment algorithm used in real-time operating systems (RTOS) with a static-priority scheduling class. At the very least, pointers to other sites would be appreciated. What I don't understand yet is how to get my code built into the kernel. See Related Links below for more information on Multi-form Codes.Looking through the scheduler source code (2.6.34, kernel/sched.c), I can see how the "pluggable" schedulers are used, and I believe I understand the interface to be implemented. Delete the additional Schedules C that were generated incorrectly by the 99M/99N screen(s).Go to the first Schedule C created from your 99M/99N screens and enter in the profession, business code and name of the business.In the example below, the florist would be MFC 1, landscaping MFC 2, and woodworking MFC 3. You can find the fillable form here: IRS Schedule C: Profit or Loss From. The IRS uses the information in Schedule C to calculate how much taxable profit you madeand assess any taxes or refunds owing. If you have multiple Schedule C forms and multiple 1099-M/1099-NEC forms, make sure you enter the correct MFC (Multi-form Code). It’s used by sole proprietors to let the IRS know how much their business made or lost in the last year. a time table Schedule task instances according to the time table within each cycle Synchronous programming languages: Esterel, Lustre, Signal 9 Example: the Car Controller Activities of a car control system.If you have already entered the 99M/99N screens, and are now looking at multiple Schedule C screens to match your 99M/99N entries, Enter the 99M/99N screens for 1099-Misc reporting or 1099-NEC for nonemployee compensation mark them for the Schedule C and be sure to enter a multi-form code that corresponds with the Schedule C involved.
HOW TO WRITE C CODE FOR RM SCHEDULING SOFTWARE
Here are the steps you need to take in order to prevent the software from producing multiple Schedules C for a single business from multiple 1099M/1099N entries: I have entered multiple 1099-Misc or 1099-NEC forms for the same business, and the software is producing multiple Schedule C forms.
