| zkanda | Hello, there is a fix in mainline linux-firmware that I want to apply to 17.10 linux-firmware, I'm following the wiki from here: https://wiki.ubuntu.com/Kernel/Dev/LinuxFirmwareMaintenance | 05:51 |
|---|---|---|
| zkanda | However there's no instruction on how to compile and get a .deb, anyone here who can point me to the right direction? | 05:53 |
| apw | zkanda: either amke a source package with dpkg-buildpackage -S and throw that in a ppa, or dpkg-buildpackage -b in a chroot | 06:37 |

| jainy | Hey, I have a bug in kernel module related to locks. So I enabled lockdep and tried to compile it; however, it is throwing me this error. Is there any way I can fix go around this and to use LOCKDEP? | 12:05 |
| jainy | Kernel built with CONFIG_DEBUG_LOCK_ALLOC which is incompatible *** with the CDDL license and will prevent the module linking stage *** from succeeding. You must rebuild your kernel without this *** option enabled. | 12:05 |
| jainy | any help is appreciated, thank you.. | 12:06 |
| jainy | also what modules in ubuntu kernel uses CDDL licence? | 12:14 |
| apw | jainy, that sounds more like somethign outside the kernel | 12:15 |
| apw | jainy, oh unless it is the vbox drivers | 12:16 |
| apw | jainy, or indeed zfs ... so it is zfs, so you would have to build with do_zfs=false | 12:17 |
| apw | assuming you don't need zfs | 12:17 |
| jainy | zfs makes sense. okay, I will try to compile with do_zfs=false | 12:18 |
| jainy | @apw, "fakeroot debian/rules DEB_BUILD_OPTIONS="debug nostrip noopt parallel=12" binary-headers binary-generic do_zfs=false" is the command line, right? | 12:19 |
| apw | you might have to put that before binary-headers, but i think that is right | 12:19 |
| apw | git grep do_zfs debian | 12:20 |
| apw | to confirm | 12:20 |
| jainy | okay, thank you | 12:20 |
| jainy | @apw, Now I an getting "I: Checking modules for generic... reading new modules...read 4614 modules. reading old modules... MISS: spl MISS: splat MISS: zavl MISS: zcommon MISS: zfs MISS: znvpair MISS: zpios MISS: zunicode" | 12:49 |
| jainy | how do I specify to skip zfs without failing there? | 12:50 |
| alexzzz | Hi all! I want to check hybrid polling on 4.10.0-40-generic and have some problems. I have ubuntu 16.04 with linux-generic-hwe-16.04 package installed. I've set scsi_mod.use_blk_mq=y and rebooted. After that i see that for my ssd drive scheduler is set to "none". I'm trying to change io_poll_delay to 0, but "echo" command fails with error: -bash: echo: write error: Invalid argument. Hope for help | 12:50 |
| apw | jainy, is it erroring there? i thought rules marked those ok when you disable | 12:50 |
| apw | it will still report them as missing, just not die | 12:51 |
| jainy | find /home/vuzzer/zless4.4/4.4/linux-4.4.0/debian/build/build-generic/ -name \*.ko | \ sed -e 's/.*\/\([^\/]*\)\.ko/\1/' | sort > /home/vuzzer/zless4.4/4.4/linux-4.4.0/debian.master/abi/4.4.0-97.120/amd64/generic.modules II: Checking modules for generic... reading new modules...read 4614 modules. reading old modules... MISS: spl MISS: splat MISS: zavl MISS: zcommon MISS: zfs MISS: znv | 12:51 |
| apw | no i don't see it saying (ignored) | 12:51 |
| jainy | EE: Missing modules (start begging for mercy) debian/rules.d/4-checks.mk:12: recipe for target 'module-check-generic' failed make: *** [module-check-generic] Error 1 | 12:51 |
| jainy | so make failed | 12:52 |
| apw | hrm, ok so that is broken | 12:52 |
| apw | do_zfs_disable:=$(shell cat $(DROOT)/zfs-modules.ignore >>$(prev_abidir)/../modules.ignore) | 12:52 |
| apw | there is al ine like that in debian/rules, you wanna make that not conditional | 12:53 |
| apw | and that should not be there in the makefile | 12:53 |
| apw | hrm | 12:53 |
| jainy | in which can I find that line ? | 12:53 |
| apw | grep is your friend | 12:54 |
| apw | but i think it is debian/rules | 12:54 |
| jainy | yes, | 12:54 |
| jainy | let me check | 12:54 |
| apw | jainy, http://paste.ubuntu.com/26139268/ something like that might do the trick | 12:55 |
| apw | if it works likely that needs applying across the board | 13:00 |
| jainy | it should be this -> ifeq ($(do_zfs),false), right? a small typo.. I am testing it now | 13:01 |
| apw | indeed it sh | 13:38 |
| apw | jainy, indeed it should be that | 13:38 |
| apw | we only normally disable zfs for cross builds, so i hadn't realised it was broke | 13:39 |
| jainy | the compilation is successfully completed | 13:45 |
| apw | great, i will test the other use cases | 13:47 |
| apw | jainy, bug #1737176 | 13:53 |
| ubot5 | bug 1737176 in linux (Ubuntu) "Disabling zfs does not always disable module checks for the zfs modules" [Low,In progress] https://launchpad.net/bugs/1737176 | 13:53 |
| jainy | Hi, I am trying to lockdep feature provided by kernel. When the deadlock occurs what I see in the kernel log is "INFO: lockdep is turned off." Even though I have provided "CONFIG_DEBUG_LOCK_ALLOC=y" I see a warning message as following: | 17:42 |
| jainy | scripts/kconfig/conf --silentoldconfig Kconfig | 17:43 |
| jainy | .config:4268:warning: override: M686 changes choice state | 17:43 |
| jainy | .config:9596:warning: override: reassigning to symbol DEBUG_LOCK_ALLOC | 17:43 |
| jainy | .config:9599:warning: override: reassigning to symbol DEBUG_SPINLOCK | 17:44 |
| jainy | Restart config... | 17:44 |
| jainy | could this be the problem? if so, how do I stop overriding these changes? | 17:45 |
| jainy | Any help is appreciated.. | 17:45 |
