F25 Kernel Version
by Christopher Covington 30 Jun '16

30 Jun '16

Hi, Apologies if this is already documented somewhere, but I wasn't able to find it. What upstream kernel version(s) might Fedora 25 use? Thanks, Cov -- Qualcomm Innovation Center, Inc. Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project

[RFC] proposal for run time memory allocation for crash kernel
by Ronit Halder 27 Jun '16

27 Jun '16

Currently, linux kernel allocates memory at the boot time for crash kernel booted using kexec system call in kernel crash. It will be very useful if we can allocate memory in run time. The user can get more usable RAM if we can do that. It is possible to allocate memory for crash kernel at the boot time using CMA (Contiguous Memory Allocator). CMA is capable of allocating big chunk of memory. At the boot time we will create one (if only low memory is used) or two (if we use both high and low memory) CMA areas of size given in "crashkernel" boot time command line parameter. This memory in CMA areas can be used by movable pages (used for disk caches, process pages, etc) if not allocated. Then the user can allocate or free memory from those CMA areas using "/sys/kernel/kexec_crash_size" sysfs entry. If the user uses high memory kernel will automatically at least 256MB low memory when the user allocates memory using mentioned sysfs enrty. In case of high memory allocation the user controls the size of reserved region in high memory with "/sys/kernel/kexec_crash_size" entry. If the size set is zero then the memory allocated in low memory will automatically be freed. I am attaching a prototype patch with the mail. Please share your opinions on my approach. This patch is only for x86 and x86_64. Please note, this patch is only a prototype just to explain my approach and get the review. Signed-off-by: Ronit Halder <ronit.crj(a)gmail.com>

[PATCHv2] generate-git-snapshot.sh
by Miguel A. Flores Silverio 23 Jun '16

The script requires LINUX_GIT to be set, preferably, in your local .bashrc. I added a quick check to see if .bashrc exits and check it first to see if LINUX_GIT is set there. Fixed the comment size to be less the 80 characters per line and tried to make some of the code fit the same description.

Backporting skl_update_other_pipe_wm intel drm fixes to the Fedora 4.6 kernel
by Hans de Goede 22 Jun '16

22 Jun '16

Hi Fedora kernel team, If you look at: https://retrace.fedoraproject.org/faf/problems/ And look for skl_update_other_pipe_wm there, you will see that it is completely dominating the problem report stats (listed 4 times on the first page, 5 times on the second). As such I'm thinking about backporting the patches: http://www.spinics.net/lists/intel-gfx/msg95595.html To the Fedora 4.6 kernel. Some of the reported problems are only a WARN_ON triggering, but there are also quite a few cases of actually wrong watermark settings causing various real problems. These patches have been around for a long time, but they missed the 4.6 merge window, and then also the 4.7 merge window, they are in next now. But IMHO we should grab them now since the problems they are causing are too big to wait for 4.8 hitting Fedora. So I would like to backport these to the 4.6 Fedora kernel and have this completed before we start pushing 4.6 updated to updates-testing. This way we can use the entire Fedora 4.6 testing phase to also test the backported fixes. Before I spend time on this, does this sound like a good plan ? I've already discussed this within the graphics team and the consensus there seems to be that this is a good idea. Regards, Hans
