[tool recommendation] tmate terminal sharing

by Christoffer Dall

Hi all, [apologies in advance for the spam nature of this message] I have been using a tool for remote collaboration and problem solving that I find perfect in the context of remote collaboration. It allows you to very easily share a terminal session even behind most firewalls etc. If you're interested, take a look at http://tmate.io/ It's based on tmux keymappings and configuration so if you already use that, you will be extra happy. -Christoffer

auto-serial-console

by Nicolas Dechesne

koen, fathi, riku, i am having issues with auto-serial-console that was initially done by marcin. https://git.linaro.org/gitweb?p=openembedded/meta-linaro.git;a=tree;f=meta-… the main issue is that it conflicts with BSP layer that uses SERIAL_CONSOLE variable. It is very much expected for a BSP layer to set SERIAL_CONSOLE variable. In which case OE will automatically start a serial console http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-core/sysvi… So when using auto-serial-console with a 'proper' BSP layer that set SERIAL_CONSOLE(S) we end up with starting the console twice, one added by OE, one by auto-serial-console. So far, all our OE builds are not using a proper BSP layer, so that's why you don't see the problem, but for our builds we use proper BSP layer... right now, auto-serial-console does 3 things: 1- figure out the serial console port from /proc/cmdline 2- start a console on #1 3- automatically login as root I believe that we should 'do something' to split them into several packages so that we get more granularity. At least #3 needs to be separated out, as #3 is a 'policy'. I would almost expect that 'being able to automatically login as root on the console' is a feature that could (should?) be added to oe-core somehow. What do you think koen? I looked into that, but there isn't any obvious (and trivial) way to do that, but it's certainly doable inside an IMAGE_FEATURE for example. this email is just to start the discussion and get some advices, e.g. i am not asking you to do it ;-) i can work on it, but want to make sure i do it right, with an 'upstream' path if possible. thx nico

OMAP: meaning of /debug/pm_debug/count

by Chao Xu

Hi all, As suggested in this wiki page ( http://www.omappedia.org/wiki/Power_Management_Debug_and_Profiling#Tracing_…), I tried to use the pm_debug debugfs. However, I don't understand the bottom half of the output. If I type "cat /sys/kernel/debug/pm_debug/count", the bottom half of the output looks like this: per_clkdm->per_pwrdm (11) usbhost_clkdm->usbhost_pwrdm (0) cam_clkdm->cam_pwrdm (0) dss_clkdm->dss_pwrdm (0) core_l4_clkdm->core_pwrdm (8) core_l3_clkdm->core_pwrdm (4) d2d_clkdm->core_pwrdm (0) sgx_clkdm->sgx_pwrdm (0) iva2_clkdm->iva2_pwrdm (0) neon_clkdm->neon_pwrdm (0) mpu_clkdm->mpu_pwrdm (0) prm_clkdm->wkup_pwrdm (0) cm_clkdm->core_pwrdm (0) I tried to google what these mean, but found nothing. Please help! Thanks. -- Regards, Chao Xu

M0 and M3 patches in linaro toolchains

by Wookey

Debconf13 (last week) considered the matter of bare-metal cross-toolchains in Debian. Ideally we would have one toolchain source package from which the existing linux native compilers, and cross-compilers are built, including bare-metal cross-compilers. There is already mechanism for adding patches for particular gcc builds, so so long as the patch set is manageable and trackable, this would be nice, and futureproof, as eventually the patch set should just evaporate as it gets upstreamed. The alternative it to simply repack the existing linaro cross-toolchain sources, but them we get to keep doing that for new releases, and we have gratuitous extra copies of gcc sources and corresponding differences between A* and M* toolchains/versions. The linaro embedded toolchains (https://launchpad.net/gcc-arm-embedded/4.7/4.7-2013-q1-update) are good, and work, both for M0 and M3. But building nominally the same thing from upstream gcc gets something where M3 works but M0 doesn't. Also they are gcc 4.7 based whilst Debian is moving to a 4.8 default. We peered at checkouts from linaro and upstream and tried to work out what the linaro patch-set for this toolchain is, and exactly where it branched off upstream, but it was confusing with a lot of noise due to version skew around some actually relevant changes. So, in order to work out if we can in fact build our bare-metal toolchains from the same sources as the existing toolchains we need to know what the actual patch-set you are maitaining looks like, and what is already upstreamed in which gcc branch/release and when the remaining patches will go upstream. Also what the 4.7 vs 4.8 status is. Knowing how this stuff is tracked might be even more useful over the longer term. Is there such info online somewhere? If not please elaborate. A mechanism for keeping the (newly-formed) Debian cross-compiler team sufficiently in the loop is probably what's needed in the longer term, unless this is all just about to get upstreamed anyway and the issue will soon become moot...? There was also discussion around the concept of making existing linux-arm cross-compilers, with M0 and M3 support included, and using spec-file jiggery-pokery to get them to DTRT for M* targets. This should be possible, but advice from anyone who's every actually tried on the gotchas would be good. cheers Wookey -- Principal hats: Linaro, Emdebian, Wookware, Balloonboard, ARM http://wookware.org/
