How about the status of this series, it's really bad, bad and still bad... to wait long time for the final judgement, especially you take extremely serious to rework it round by round, finaly you receive nothing. Everyone's work should be repected! Technically, I don't think it's very hard to say yes or no (what's your concerns) for the patch set. If you give your objections and convince me, then I will drop it, that's nothing. Hopefully our maintainers can take the responsibility that they should take, I totally understand that our maintainers are very busy and will face tens of thousands of mails. But, YOU ARE THE MAINTAINER! Responsiblity!Responsiblity!! Still TMD f*cking FucResponsiblity!!!

Everyone's work should be repected! I've trimmed the rest of your response as it wasn't especially constructive. Please can you try to keep things civil, even when you're frustrated? It's not very pleasant being on the end of a rant. One likely explanation for you not getting a reply on your patches is that I've discovered many of your emails have ended up in my spam, for some reason. I'm using gmail for my inbox so, if Bjorn is doing that as well, then there's a good chance he hasn't seen them either. The other thing to keep in mind is that the 5.16 merge window opened today and you posted the latest version of your patches on Wednesday. That doesn't really leave enough time for the patches to be reviewed (noting that patch 3 is new in this version and the kernel build robot was still complaining on Friday), queued and put into linux-next, so I would suspect that this series is looking more like 5.17 material and therefore not a priority for maintainers at the moment. Your best is probably to post a v5, with the kbuild warnings addressed, when -rc1 is released in a couple of weeks. I'm not sure how to fix the spam issue though :( Will
Hi Will, Thanks for the feedback!

I'm very sorry about the non-constructived response, and I'd like to take this chance to withdraw them entirely... personally this is not a good example in terms of the mood or the way of expression. > > One likely explanation for you not getting a reply on your patches is that > I've discovered many of your emails have ended up in my spam, for some > reason.

Good idea. There are other maintainers who would ignore you indefinitely for uncalled for explosions like that. And then you would have achieved the opposite of what you were aiming for, with that rant. To Will's point, you can always read Documentation/process/ while waiting for your patches to get reviewed - there the whole process is explained and what the best ways and times are to send a patchset. HTH.

Actually that's my original intention, especially when you take lots of serious effors to rework it round by round, but no one say YES or NO, which is really frustrating. Hopefully the newbies can also be treated fairly in the community. During my working experience in the community before, lot's of nice maintainers give me very deep impression. What a splendid memory! > > To Will's point, you can always read Documentation/process/ while > waiting for your patches to get reviewed - there the whole process is > explained and what the best ways and times are to send a patchset.

Well, try to put yourself in the maintainer's shoes, maybe that would answer some of that frustration: - Most of the maintainers are overworked and backlogged until forever. - If you rework something and you don't get an answer, maybe the maintainer is not sure yet and is thinking about the pros and cons of taking that patch. Greg has formulated this particular issue of the maintainers very nicely: "Seriously. It's easier for the maintainer to not accept your code at all. To accept it, it takes time to review it, apply it, send it on up the development chain, handle any problems that might happen with the patch, accept responsibility for the patch, possibly fix any problems that happen later on when you disappear, and maintain it for the next 20 years. That's a lot of work that you are asking someone else to do on your behalf… So your goal is, when sending a patch, to give me no excuse to not accept it. To make it such that if I ignore it, or reject it, I am the one that is the problem here, not you." And this thing is not really clear to all submitters - once their patch(es) is applied, they're done. But maintainers have to deal with that code forever. So before you send your patchset, try to think as a maintainer and think whether your change makes sense for the *whole* tree and whether maintaining it forward would be easy. - Did I say that maintainers are overworked? Submitters don't see the amount of work maintainers do in the background, testing everything and fixing build issues and bugs. Because most of the time, submitters submit and the cleanups and bugs get mopped after them by the maintainers - not the submitters. Look at how some trees resort to maintainer *groups* because a single maintainer simply doesn't scale, at the risk of a burnout or whatever nasty. And those maintainer groups have *all* their hands full. > Hopefully the newbies can also be treated fairly in the community. Newbies are treated fairly in the community - especially those who come prepared and try to understand why the maintainers say things they way they do and listen to feedback. If there are examples against that, we would all like to know about them. I sincerely hope that explains the situation and hope that it'll help you see it from the maintainers' POV too and maybe help you deal with future submissions a lot better. Thx.
The issue of commit d91525eb8ee6 ("ACPI, EINJ: Enhance error injection tolerance level") on x86 is also happened on our own ARM64 platform. We sent a patch[1] trying to fix this issue in an arch-specific way as x86 does at first, but according to the suggestion from Lorenzo Pieralisi and Catalin Marinas, we can consolidate the PCI MCFG part then fix it in a more common way, that's why this patch series comes. [1] https://marc.info/?l=linux-arm-kernel&m=163108478627166&w=2 --- Change from v3 to v4: - Add a new patch (patch #3) to address the quirk ECAM access issue. Because the normal ECAM config space can be accessed in a lockless way, so we don't need the mutual exclusion with the EINJ action. But those quirks maybe break this rule and corrupt the configuration access, reserve its MCFG address regions in this case to avoid that happens. - Add another patch (patch #4) to log the PCI MCFG entry parse message per the suggestion from Bjorn Helgaas. The output on ARM64 as: ACPI: MCFG entry for domain 0000 [bus 00-0f] at [mem 0x50000000-0x50ffffff] (base 0x50000000) - Commit message updated with more details of patch #2 Change from v2 to v3: - Address the comments of Lorenzo Pieralisi about the CONFIG_PCI dependence issue in APEI module (patch #2) Change from v1 to v2: - Fix the "undefined reference to `pci_mmcfg_list'" build error in case of PCI_CONFIG=n, reported by the kernel test robot Xuesong Chen (4): PCI: MCFG: Consolidate the separate PCI MCFG table entry list ACPI: APEI: Filter the PCI MCFG address with an arch-agnostic method ACPI: APEI: Reserve the MCFG address for quirk ECAM implementation PCI: MCFG: Add the MCFG entry parse log message arch/x86/include/asm/pci_x86.h | 17 +---------- arch/x86/pci/mmconfig-shared.c | 30 ------------------- drivers/acpi/apei/apei-base.c | 68 ++++++++++++++++++++++++++++++++---------- drivers/acpi/pci_mcfg.c | 46 +++++++++++++++------------- drivers/pci/pci.c | 2 ++ drivers/pci/quirks.c | 2 ++ include/linux/pci.h | 18 +++++++++++ 7 files changed, 101 insertions(+), 82 deletions(-)
