Merge/sound upstream 20200219 #1805

kv2019i · 2020-02-19T10:34:56Z

Upstream merge 20200219. Lots of changes to ASoC and Soundwire, so please test.

Fix some typos in the comments. Also fix coding style. [Sean Christopherson rewrites the comment of write_fault_to_shadow_pgtable field in struct kvm_vcpu_arch.] Signed-off-by: Miaohe Lin <linmiaohe@huawei.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Hardcode the EPT page-walk level for L2 to be 4 levels, as KVM's MMU currently also hardcodes the page walk level for nested EPT to be 4 levels. The L2 guest is all but guaranteed to soft hang on its first instruction when L1 is using EPT, as KVM will construct 4-level page tables and then tell hardware to use 5-level page tables. Fixes: 855feb6 ("KVM: MMU: Add 5 level EPT & Shadow page table support.") Cc: stable@vger.kernel.org Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Define PT_MAX_FULL_LEVELS as PT64_ROOT_MAX_LEVEL, i.e. 5, to fix shadow paging for 5-level guest page tables. PT_MAX_FULL_LEVELS is used to size the arrays that track guest pages table information, i.e. using a "max levels" of 4 causes KVM to access garbage beyond the end of an array when querying state for level 5 entries. E.g. FNAME(gpte_changed) will read garbage and most likely return %true for a level 5 entry, soft-hanging the guest because FNAME(fetch) will restart the guest instead of creating SPTEs because it thinks the guest PTE has changed. Note, KVM doesn't yet support 5-level nested EPT, so PT_MAX_FULL_LEVELS gets to stay "4" for the PTTYPE_EPT case. Fixes: 855feb6 ("KVM: MMU: Add 5 level EPT & Shadow page table support.")

The check cpu->hv_clock.system_time < 0 is redundant since system_time is a u64 and hence can never be less than zero. But what was actually meant is to check that the result is positive, since kernel_ns and v->kvm->arch.kvmclock_offset are both s64.

It seems most SOF tests are broken after the upstream changes. Probe and firmware load are ok, but playback/record is not working. On UP2, playback attempt fails to:

The playback errors happen also with broonie/for-next, so SOF is now broken in upstream. :(

@plbossart Hmm, bisect points to this patch now:

@kv2019i I think this should go in side the previous if no?

should be if (!component->opened[substream->stream]

@plbossart Heh, with this fixes, playback fails again...

but if I add this negation, then things don't work for me again. So it looks like the open needs to happen the second time this routine is called?

right, so the state machine looks very odd here...

@kv2019i what happens when there are multiple capture/playback streams opened? I feel like the opened state is a bad idea

@ranj063 Ack. The substreams can be multiple playback streams, so my first patch worked by accident.

I think only sensible thing is to revert the whole thing. I uploaded the patch now, and will sent to the list in a minute.

that ref count makes no sense to me (including in the original case). We should only increment in case there's no error, and in addition there are already module refcounts, not sure why we need new ones on top?

@plbossart Ok let me remove. I tried first to not touch these, but then it completely broke driver load-reload... I'll try again.

ASoC component open/close and snd_soc_component_module_get/put are called independently for each component-substream pair, so the logic in the reverted patch was not sufficient and led to PCM playback and module unload errors.

i need the SoundWire patches + the rest of Morimoto-san, so I'd rather merge and see what happens upstream later.

#1802 currently has 52 patches, it's unreviewable :-(

Aa, ok. In that case, ok to merge this. Let's see what kind of CI feedback we get. I have not done full local test on this, so if CI doesn't provide sane results, then we have very thin data on how healthy this is (I did basic tests with CFL and APL now).

I can do more tests tomorrow or do a new rebase for 20200220 if this doesn't go in.

plbossart · 2020-02-19T19:15:21Z

CI is in a ternary logic mode it seems, it reports an error with BDW but no details available at all.
I've ignored all results this morning. @xiulipan @fredoh9 @wenqingfu FYI, CI cannot be trusted at the moment. I know everyone is trying to do their best but at this point we have to use our own local tests and engineering judgement...

@plbossart are the module load/unload failures because of missing modules in the kmod script?

@plbossart I think some network failure cause the CI failure recently, will check if the network is recovery now.

I think it's the new compress module. We need to add it to the kmod scripts:

@plbossart @xiulipan @ranj063 My local tests are all fine, tested on SDW, HDA and I2S platforms an no issues fine. CI looks good as well. The kmod error comes from the compress/probes patch, so that should be fine as well.

I'll give you and others a few more hours to test, but when Pierre you come online, let's go ahead and merge this.

@kv2019i so with a couple of different patches from you and @morimoto, how do we go about this? revert and then revisit when one of those patches is accepted?

@plbossart As it is a lot patches, just to double-check, should I use github "Create a merge commit" or "Rebase and merge" for this? I already the merge commit in the branch I pushed, so will it create another one if I choose "Create a merge commit"..?

I always use 'Create a merge commit', not sure what happens with the 'rebase' option.

Hmm, are you sure? :) I used that now, but it created a bit weird merge commit with my github account name in the from-field. When I looked at your merges, they look different. So either you have configured github differently, or you use the "rebase-and-merged" after all.

FYI @ranj063

Let me know if there is anything other odd in the merge.
