At the moment, the only resources I've found are the 4212.svd-tiva-11073.zip file (which is unofficial and oddly structured) and Cortex Microcontroller Software Interface Standard (CMSIS) for Stellaris® MCUs: Device Header Files spmc018.zip (which contains a Windows executable that does not run on Windows 7 or Vista 64-bit, and apparently only has Stellaris devices).
There are also various postings in this and other E2E forums suggesting that some TI folks sometimes work on providing these, but no sign that there's an active plan to make CMSIS available in a robust and supported form.
At this time I'm specifically interested in CMSIS-CORE using gcc-arm embedded, but the other components are likely to become important.
We do not have a full CMSIS package available for Tiva C series devices but here is a list of what is available and in the works. The first two items you've already identified.
4212.svd-tiva-11073.zip - package for tool vendors to add support for Tiva products in their IDEs.
spmc018.zip - contains device header files for Stellaris devices (well before Tiva).
We plan to have CMSIS device header files available for Tiva devices in Q1 2014. This sounds like what you are looking for. Is this correct?
There is also an application note describing how to get the CMSIS DSP library to compile in CCS expected beginning of 2014. This is same app note mentioned in this thread.

Hi Joel.
Any news ?
Do you plan to release it for TM4C129X as well? Thank you

Are CMSIS device header files still scheduled for release this quarter? They're not in TivaWare_C_Series-2.1.0.12573 released 07-FEB-2014, and spmc018 from http://www.ti.com/tool/cmsis_device_headers hasn't been updated.
FWIW, I found CMSIS headers for TM4C123 and TM4C129 on github, but have no idea where they came from, so an official source would be truly appreciated.
Boy - youse guys are pushy - are you not? Give poor Joel (some) time! (its only been 7 months...) (kidding.....)
Does it not make far more sense to address the, "always present - remarkably responsive," Amit?
Amit - while not (your job) perhaps you can assist? Merci...
Amit,
As always - thank you - what a valuable resource you've become!
Guys here have been patient - at least now some, "forward motion" seems possible...
Hello All,
Might this be of help
http://www.ti.com/lit/an/spma041c/spma041c.pdf
Regards
Amit
"Might this"...This reporter leaves such judgment to requesting others.
Seven months - essentially silence.
One "call" to Amit - instantaneous, caring response.

Thanks, but no. That's only for the DSP functionality (and, by its title, only relevant to CCS). My original request was for device headers.
CMSIS device headers (providing structure layouts for each peripheral module, along with the masks and shifts necessary to access bit fields within peripheral registers) are the ARM standard interface for Cortex-M devices. As I note in this posting, TI does not appear to provide these with any regularity. I have found the CMSIS interface--which maps directly to the vendor (TI) register and bitfield names described in the datasheets---much easier to use than wrapper libraries like TivaWare, which often involve function call overhead and require reading the library source to figure out exactly what's going on.
I suspect generating device-specific headers should be pretty easy with existing ARM tools and descriptive files TI probably already has. Although I understand they do provide the means to bypass TI's preferred developer interface, they are the ARM standard interface, and allow advanced ARM developers to more quickly adopt TI ARM chips. It would be very helpful if they could be made available as normal practice for all TI's ARM Cortex-M MCU and SOC products.

After seven months - six unanswered posts - help arrives (admittedly imperfect) but the effort was made - silence broken.
Thanks/praise to Amit a bit, "light" was it not? You've made your case - bit more gratitude may (better) aid/abet...
Your post here (today) reached to 900 visits. (reflects fair - but not major - user interest...most here employ driver lib.)
(recall neither Amit nor this reporter caused/contributed to (past) delayed response...)
Can this, "dead horse" be beaten any harder? (perchance give the guy some time/room to "work" back channels...)
CMSIS 4's primary enhancement is CMSIS-Driver, which I believe significantly overlaps TivaWare's functionality. It'd be nice to have, but for my needs CMSIS-Core is the fundamental missing piece.
Anticipatory thanks and praise to Amit for any resolution s/he may be able to facilitate.
Peter Bigot said:CMSIS-Core is the fundamental NEED missing piece (edit: cb1).
That's key data - thanks for that. We should avoid, "frustrating" Amit's/other vendor efforts by imprecise targeting.
Your post sat for months - I "sensed" that a different approach had better odds - thus pinged the, "always present" Amit!
So glad now that you've better registered your appreciation of Amit. Recall that he was under no obligation to assist - his heart/desire to assist is great. Knowing that - my choice of "target" (i.e. Amit) proved most sound...
Believe if we give him some room/time - monitor here for vendor questions - your CMSIS-Core desire has best chance...
(note: in past 2 days - this post (long quiet) has logged over 150 new visits - go figure...)
Sigh, so I will try again.
TI: When will you have the CMSIS DEVICE header files for the TIva 129 and Tiva 123????
Putting up the "CMSIS compliant" logo is wonderful and all, but the actual header files would help me in the port of a real-time kernel I'm doing.
Thanks!

I just heard from my local FAE here in Florida.
He states that they intend to release the TM4C123 CMSIS files (no time frame) and that:
"At this time, no further development efforts are planned for the CMSIS headers to include the TM4C129x devices."
