[opensuse-kernel] Kernel:linux-next: ARM

by Matwey V. Kornilov

Hi, Could we have ARM builds for Kernel:linux-next? The reason behind is that our kernel in Kernel:HEAD usually not even builds for early rc-s due to carefully applied upstream bugs. It would be great to be able to detect build failures as early as possible and report the problems upstream. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] 32bit 13.2 panic when no apm=off on cmdline

by Felix Miata

I just spent most of the past several days getting this Intel 2 core E6700 P965/ICH8 RAID1 system switched from 11.4 to 13.1 and 13.2 in multiboot via Grub Legacy on primary partition. To do so, I used a single HD Intel 2 core E7600 mule/testing system with 2 new disks added, using running 13.1's yast to build all RAID devices on the new pair prior to initializing 13.1 installation. I eventually got both 13.1 and 13.2 booting and running satisfactorily, restored an rsync backup of user data to the RAID, then shut down this system and moved the RAID pair to it. 13.1 worked satisfactorily immediately, including NIC config retaining fixed IP on eth0. 13.2 spewed trap/segfault errors in a neverending stream virtually instantly in trying to boot from some cmdline config attempts. Many of the others ended in trap data, blinking keyboard LEDs and frozen screen claiming reboot would occur in 90 seconds. The failsafe stanza provided boot, but during init many errors were spewed on tty1 among normal messages. Before I even thought to try failsafe, I chrooted from 13.1 to zypper up and update kernel from 3.16.6 to 3.16.7, then when that didn't help, TW's 3.18.3, also no help. I booted failsafe taking one more option off cmdline each time about 8 times until the only rescue options left were noresume and apm=off, so apm=off definitely functions to get a working boot, yet not without seeing the error stream on tty1. The last attempt without apm=off produced the frozen screen and keyboard condition. I looked in the mailing list archives and Bugzilla, but didn't find anything I recognized as similar. Is there something journalctl can capture that can help someone help me figure out if this is a 13.2 bug that may have escaped discovery before now? FWIW, installing new kernels via chroot produces 13.2 initrds 50% bigger than those happening on account of zypper up processing. Here out of habit, zypper up/dup excludes adding a new kernel. I zypper al kernel* first, up, unlock, then repeat, so that the new kernel's initrd is guaranteed to be built once only. Also FWIW, 13.1 (like 11.4 did) requires clock=hpet on cmdline to prevent clock apparently overpowering ntp. While asleep last night it gained something like 10 minutes in 6 hours. -- "The wise are known for their understanding, and pleasant words are persuasive."

[opensuse-kernel] Set SCSI_MQ_DEFAULT=n in Kernel:stable

by David Sterba

Hi, currently the scsi-mq is set to Y, since 3.18-rc1 merge. The option enables a feature that makes advantage of enterprise-class storage. It's known not to perform well on slower devices [1] and lacks scheduler support. We'll set the option to N in our stable kernels. The lack of scheduler support can cause significant performance drop. Vojtech reports 10-50x slowdown on random read workloads, the disks seek all over the platters due to the missing io scheduler optimizations. As most of our users are not likely to run on high-end storage devices or otherwise benefit from the scsi-mq feature, I believe it's safe to turn the scsi-mq option off. Once the io scheduler support is availabe we can enable it again. The change will be done for all architectures and all kernel flavors (30 changes in total).

[opensuse-kernel] optimizing ext4 bytes-per-inode on large arrays installed on opensuse?

by lyndat3＠your-mail.com

I'm replacing a RAID array for a NAS. I'm about to create a the ext4 partition on the primary, full-disk LV. The original LV had been formatted ext4, with defaults, mkfs.ext4 /dev/VG0/NAS03 I'm looking at the original drive's usage, hoping to optimize the new drive. /bin/df /dev/VG0/NAS03 Filesystem 1K-blocks Used Available Use% Mounted on /dev/mapper/VG0-NAS03 1548182724 1383153132 86363468 95% /NAS03 /bin/df -i /dev/VG0/NAS03 Filesystem Inodes IUsed IFree IUse% Mounted on /dev/mapper/VG0-NAS03 98312192 1182797 97129395 2% /NAS03 For 1383153132 1K blocks = 1,416,348,807,168 bytes in use results in an effective 'bytes-per-inode' 1,416,348,807,168 / 1182797 = 1,197,457 bytes/inode The ext4 fs defaults for mke2fs on opensuse are cat /etc/mke2fs.conf [defaults] base_features = sparse_super,filetype,resize_inode,dir_index,ext_attr default_mntopts = acl,user_xattr enable_periodic_fsck = 0 blocksize = 4096 inode_size = 256 inode_ratio = 16384 [fs_types] ... ext4 = { features = has_journal,extent,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize auto_64-bit_support = 1 inode_size = 256 } ...

[opensuse-kernel] large data transfer rate slowdows over NFSv4 local lan with kernel 3.19.3x ?

by lyndat3＠your-mail.com

I was just pinged on this by a client; I can reproduce it here. I have two opensuse 13.2 machines. NFS xfers -- cp & rsync -- between them slow to a crawl: < 1 MB/sec in the worst case, over a 1Gb local lan. Chats @ #networking/#nfs suggest this is a kernel+NFS issue. So checking here 1st. Both machines run kernel uname -rm 3.19.3-1.gf10e7fc-default x86_64 Both have NFS installed. Packages include nfs-client-1.3.0-4.2.1.x86_64 nfs-kernel-server-1.3.0-4.2.1.x86_64 The server's store is at /NAS/NAS1 it's on a LV on a software (mdadm v3.3.1) RAID-10 array.

[opensuse-kernel] how to control/modify early framebuffer & resolution on UEFI-booted kernel 3.19.2?

by lyndat3＠your-mail.com

I'll start here -- because it is opensuse and kernel-related -- but don't know if this is the ultimately right place to ask. I'm working on setting console video resolution on an opensuse 13.2 server. I want 'hi-res' (to the extent possible), text-only display from grub menu, through completion of linux boot. My eventual questions are (1) why is 'efifb' used? it's supposed to be Mac-only (2) how do I change 'efifb' resolution? (3) can nouveaufb replace efifb completely? I have installed uname -r 3.19.2-3.gd8856ce-default It's booting UEFI dmesg | grep "efi: EFI" [ 0.000000] efi: EFI v2.31 by American Megatrends The mobo/cpu is SuperMicro + Intel Xeon Haswell v3.

But, from grub menu display up until that point, i.e. prior to the fb handoff, the display resolution used by 'efifb' is currently limited to 800x600. Available EFI video modes are grub> videoinfo List of supported video modes: Legend: mask/position=red/green/blue/reserved ... Adapter 'EFI GOP Driver': * 0x000 800 x 600 x 32 (3200) Direct color, mask: 8/8/8/8/ pos: 16/8/0/24 0x001 1024 x 768 x 32 (4096) Direct color, mask: 8/8/8/8/ pos: 16/8/0/24 According to https://www.kernel.org/doc/Documentation/fb/efifb.txt "... efifb is only for EFI booted Intel Macs. ..." This is not a Mac, so why is the 'efifb' being used? Since this is post-grub2-menu, it seems something in the opensuse install/setup is possibly misidentifying the hardware. Randomly trying each of video=efifb:0x001 video=efifb:1024x768 video=efifb:1024x768x32 to GRUB_CMDLINE_LINUX="... video=efifb:<...> video=HDMI-A-1:1920x1080@60" had no effect. 'nouveaufb' clearly has the mode support I need. Is it possible to get the efi-booted kernel to use it @ early display, immediately post-grub2-menu?
