The https://devel.rtems.org/wiki/GSoC/GettingStarted pages asks you to
post to the lists your patch and then update the GSoC 2016 page at
https://devel.rtems.org/wiki/GSoC/2016. Can you please do this? Thanks.

I have updated the Open Project TraceTool wiki page. Please see have a
look and see if that answers your questions.

Currently there is no CTF support in RTEMS.

Live trace is a function of the back end of the Capture Engine. The
Capture Engine at it's top takes in records from generated by barectf
and buffers them and at it's back end it interfaces to transports to get
the data off the target. This architecture disconnects the transport
from the tracing and allows different transports to be used. For example
it could TCP, or UDP, JTAG, SPI, or a UART. RTEMS users have a wide
range of hardware and often debug interfaces are unique because of the
costs they can add to hardware. Consider a satellite, adding a whole
network interface, MAC and TCP/IP stack to trace during development is
silly because there is no network in space yet all the hardware would
need to be provided for and at a minimum it would take valuable board
space. The key role of the Capture Engine is to provide a simple API for
the transport layers. This work in the Capture Engine is either
partially done or needs to be done.
A key function of the Capture engine is to provide concurrent buffering.
This means low overhead buffering safe in an SMP context. This is harder
than it appears. Keeping it separate from barectf and rtems-tld is
important.

These are good GSoC tasks and we welcome your interest in the work.

Re: Participation in GSoC 2016
Hi, I've been a little busy with my semester end exams and other things recently. But I have spent time looking into the RTEMS Priority Scheduler with Processor Affinities and the paper mentioned in the trac ticket. At this point, I have a decent understanding of the paper and its algorithm and am looking into how we may implement it in RTEMS. To this end, I am looking for help / guidance. This would be a good project. I would add a few steps to simply implementing it. + Update the scheduling simulator since it is a lot easier to test using that. It is also easier to ensure you keep the same behavior. This sounds like it would be in important part of the implementation of the paper. However, I do not know anything about the existing scheduling simulator. Any links to this and basic pointers on how I should go about extending it would be a great start. I'll incorporate this into my draft proposal as soon as I have a better idea of what needs to be done. + Propose criteria for knowing if the new algorithm is really better for RTEMS than the old one. Evaluating algorithms for RTEMS use involves big-O of the algorithm, data space requirements (and big-O of that), global knowledge required, and maybe other factors. The new algorithm is almost definitely worse in time and space than the existing algorithm. Based on a preliminary analysis, it will be able to use the existing Priority Affinity Scheduler for the most part and add a O(|E|) complexity to each thread blocking and unblocking operation. Here, E is the set of all processor affinity assignments, so it will approximately add an extra linear increase in scheduling overhead w.r.t. the number of processes that use this scheduler. I haven't specifically looked into the space requirements, but it will be worse than the existing scheduler. However, the point to realize is that after these changes, more user programs that set processor affinities will be able to meet their deadlines as compared to the existing scheduler. This should happen despite the higher scheduling overheads. + Testing on scheduling simulator and in RTEMS testsuite to ensure it is functionally identical to the current algorithm. Once again, some pointers tot he scheduling simulator would help me a lot. If the algorithm is functionally identical to the current one and superior in execution time/data requirements, then replacing it is a no brainer. If there are trade-offs on when one is better than the other in real life, then we will all have to characterize those. I was thinking more along the lines of writing a new scheduler instead of replacing the existing one. A PriorityStringAPA scheduler that pretty much reuses all the existing priority affinity scheduler code apart from the two operations. This is because, with some task sets where the affinity assignments are not too restrictive, the lower overheads of the existing scheduler may be preferred over the new one. I have also been writing my draft proposal for GSoC. A version is currently available on GDrive and a link has been put on on the student tracking page. However, I wanted to ask if sharing a PDF of the proposal would be possible. Since, I would be more comfortable in making the entire proposal in Latex and sharing the final PDF. If not, I can keep working on the proposal in Google Docs. -- Thanking You, Darshit Shah signature.asc Description: PGP signature ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
Re: Participation in GSoC 2016
Joel might answer about the state of the scheduling simulator. I believe you eventually have to copy-paste your application into a form, so it is better if you stick to plain text. I don't even know if you can put images in. You may optionally link to a generated PDF, too.

I think we both misread it. The calloc() is for data per port. The copy is
copying
the per port configuration data. They are different. Notice
Console_Port_Data
vs Console_Port_Tbl.
I think this is OK on closer look.
Anything else.

Re: GSOC 2016
Joel should comment on this. He has been making a recent effort at unifying the PCI implementations in the BSP layer. However, we also have the new "drvmgr" framework in cpukit/libdrvmgr that supports PCI plus a lot of other devices and busses.

Both are only used by SPARC BSPs at the moment but would be good to bring over to the other. I left a ticket (https://devel.rtems.org/ticket/2635) where some PowerPC BSPs couldn't immediately use my shared pci_find_device.c because I didn't promote out pci_scan(). It would be good to get that issue addressed and then start migrating BSPs to use libpci and whatever is useful from what I did cleanup up the pc386. Between the two of those, there should be a nice GSoC project and it would be appreciated. + migrate to use of libpci including enhancements as needed I do not know enough about the driver manager to know which BSPs should use it. The pc386 may be a good candidate. I think if the devices are dynamically detected on the BSP, it makes sense. But not sure. --joel > > On Tue, Mar 8, 2016 at 12:19 PM, animesh pathak > wrote: > > Hi, > > Thanks for informing.

Re: A virtio front-end driver for RTEMS
I'm glad to hear this. The path of least resistance would be to merge the driver into the pc386 BSP on rtems.git. That bsp tree is currently undergoing a lot of activity, but once you get your driver merged I would imagine it is not too hard to maintain. It would also be of interest to get instructions for using RTEMS-pc386 on KVM added to the RTEMS wiki. By merging the driver into RTEMS it will be more easily shared and can be community-maintained especially if we can eventually get the KVM version included in our planned continuous integration efforts.

[PATCH 00/32] Per Function Section Series
This series of patches adds per-function section linking to every BSP that it didn't obviously break. Obviously breaking was a significant reduction in the size of the C++ samples. If C++ was not supported on the target, then checking the size of other samples. There should now be no BSP custom files which do not either use per-function sections or have them disabled with a pointer to a ticket.

It was a test command so I could very explicitly control calling open(), write(), and close(). I had debug printk's turned on to see the register accesses for each. That functionally does the same operations if you had a set of small files but you wouldn't see a break between open(), write() and close(). I don't know if it is worth being in the tree or not. It was a quickly thrown together utility for testing. If it has value, then we can rename it and add some requirements. My lspci command is similar. If we get every BSP to standard PCI support, it might be useful but until then, it is just a test utility. > Chris > ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

I had debug printk's turned on to see the register accesses for each. Best to keep as an example. That functionally does the same operations if you had a set of small files but you wouldn't see a break between open(), write() and close(). Files are easy to create and add to the root fs. There should be some in /etc. I don't know if it is worth being in the tree or not. It was a quickly thrown together utility for testing. If it has value, then we can rename it and add some requirements. I say out of the tree. Commands are easy to add and difficult to remove. My lspci command is similar. If we get every BSP to standard PCI support, it might be useful but until then, it is just a test utility. This is useful. If it is not present someone will just invent it again. The doco needs to be added to docs repo. The shell doco source is ok to change. :) Chris ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

I attach a couple of files from a friend of mine, Andi, who knows and
works with cmake. I have not tried them and I do not know if they work.
If you have any questions please feel free to ask.

Regarding GSOC 2016 BBB Mentor
Hi, I am ready with RTEMS hello world on Beagle bone black ( https://www.youtube.com/watch?v=FyOHU02bsvw&index=6&list=PL2muodf7ZnYcS18wkilESuJpZGj4mYSMJ) and interested to improve BBB BSP . Currently I am testing GPIO and will work on PWM driver for showcasing on my proposal. But I am afraid that I have not listened anything from Ben Gras. Is some else will mentor me ? If not then should I stick with my BBB idea or go for another RTEMS project for which some one can mentor me ? I have already asked this question before but I am little worried that is why I created new thread. Any suggestions will be appreciated. ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
Re: Regarding GSOC 2016 BBB Mentor
Hello Punit, I was working on porting the MicroMonitor (uMon) bootloader to the BBB last year's GSoC 2015. There is actually still some work that needs to be done. At the moment, Ethernet functionality and booting application images still need to be implemented to get it to the point of making it a usable bootloader for the BBB. If you're interested in pursuing this as a project, feel free to drop on by at umon-de...@rtems.org if you have any questions.
