I don't understand your question. Write in detail what you are doing and what the problem is. |
|
|
check your DTS settings. |
|
The DTS is consistent with the normal display DTS file, and whether the DTS problem can be excluded. |
|
The version of the image ? |
|
Version image Armbian |
|
Debian 9 |
|
I ask the version of the image Armbian which does not work HDMI. |
|
I don't quite understand what you mean Kernel ：7f258e5d352505dcb38ce871eff0d72e1ef94206 (Compiled kernel HDMI does not display) Hardware：（Phicomm N1） |

commit d0a255e795ab976481565f6ac178314b34fbf891 upstream. A deadlock with this stacktrace was observed. The loop thread does a GFP_KERNEL allocation, it calls into dm-bufio shrinker and the shrinker depends on I/O completion in the dm-bufio subsystem. In order to fix the deadlock (and other similar ones), we set the flag PF_MEMALLOC_NOIO at loop thread entry.

commit 41ba17f20ea835c489e77bd54e2da73184e22060 upstream.
Commit <684d984038aa> ('powerpc/powernv: Add debugfs interface for
imc-mode and imc') added debugfs interface for the nest imc pmu
devices to support changing of different ucode modes. Primarily adding
this capability for debug. But when doing so, the code did not
consider the case of cpu-less nodes. So when reading the _cmd_ or
_mode_ file of a cpu-less node will create this crash.

Patch fixes the issue with a more robust check for vbase to NULL.

After patch, ls output for the debugfs imc directory
# ls /sys/kernel/debug/powerpc/imc/
imc_cmd_0 imc_cmd_8 imc_mode_0 imc_mode_8
Actual bug here is that, we have two loops with potentially different
loop counts. That is, in imc_get_mem_addr_nest(), loop count is
obtained from the dt entries. But in case of export_imc_mode_and_cmd(),
loop was based on for_each_nid() count. Patch fixes the loop count in
latter based on the struct mem_info. Ideally it would be better to
have array size in struct imc_pmu.

commit f9c645621a28e37813a1de96d9cbd89cde94a1e4 upstream. Masoud Sharbiani noticed that commit 29ef680 ("memcg, oom: move out_of_memory back to the charge path") broke memcg OOM called from __xfs_filemap_fault() path. It turned out that try_charge() is retrying forever without making forward progress because mem_cgroup_oom(GFP_NOFS) cannot invoke the OOM killer due to commit 3da88fb ("mm, oom: move GFP_NOFS check to out_of_memory"). Allowing forced charge due to being unable to invoke memcg OOM killer will lead to global OOM situation. Also, just returning -ENOMEM will be risky because OOM path is lost and some paths (e.g. get_user_pages()) will leak -ENOMEM. Therefore, invoking memcg OOM killer (despite GFP_NOFS) will be the only choice we can choose for now. Until 29ef680, we were able to invoke memcg OOM killer when GFP_KERNEL reclaim failed [1]. But since 29ef680, we need to invoke memcg OOM killer when GFP_NOFS reclaim failed [2]. Although in the past we did invoke memcg OOM killer for GFP_NOFS [3], we might get pre-mature memcg OOM reports due to this patch.
