stable/LTS test report from KernelCI (2023-12-08)

by Gustavo Padovan

Hello, As discussed with Greg at LPC, we are starting an iterative process to deliver meaningful stable test reports from KernelCI. As Greg pointed out, he doesn't look at the current reports sent automatically from KernelCI. Those are not clean enough to help the stable release process, so we discussed starting over again. This reporting process is a learning exercise, growing over time. We are starting small with data we can verify manually (at first) to make sure we are not introducing noise or reporting flakes and false-positives. The feedback loop will teach us how to filter the results and report with incremental automation of the steps. Today we are starting with build and boot tests (for the hardware platforms in KernelCI with sustained availability over time). Then, at every iteration we try to improve it, increasing the coverage and data visualization. Feedback is really important. Eventually, we will also have this report implemented in the upcoming KernelCI Web Dashboard. This work is a contribution from Collabora(on behalf of its clients) to improve the Kernel Integration as whole. Moving forward, Shreeya Patel, from the Collabora team will be taking on the responsibilities of delivering these reports. Without further ado, here's our first report: ## stable-rc HEADs: Date: 2023-12-08 6.1: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/… 5:15: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/… 5.10: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/… 5:4: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/… * 6.6 stable-rc was not added in KernelCI yet, but we plan to add it next week. ## Build failures: No build failures seen for the stable-rc/queue commit heads for 6.1/5.15/5.10/5.4 \o/ ## Boot failures: No **new** boot failures seen for the stable-rc/queue commit heads for 6.1/5.15/5.10/5.4 \o/ (for the time being we are leaving existing failures behind) ## Considerations All this data is available in the legacy KernelCI Web Dashboard - https://linux.kernelci.org/ - but not easily filtered there. The data in this report was checked manually. As we evolve this report, we want to add traceability of the information, making it really easy for anyone to dig deeper for more info, logs, etc. The report covers the hardware platforms in KernelCI with sustained availability over time - we will detail this further in future reports. We opted to make the report really simple as you can see above. It is just an initial spark. From here your feedback will drive the process. So really really tell us what you want to see next. We want FEEDBACK! Best, - Gus -- Gustavo Padovan Kernel Lead Collabora Ltd. Platinum Building, St John's Innovation Park Cambridge CB4 0DS, UK Registered in England & Wales, no. 5513718

Further cleanups for pci_iounmap() and lib/iomap.c discussion

by Philipp Stanner

Hola, This is a discussion about whether we want to move lib/iomap.c and remove the remaining pci_io(un)map() definition of s390. That would be followup work on our pci_iounmap() cleanup [1] that was discussed here [2] (but is not yet merged). The summary from the last discussions was: * GENERIC_IOMAP is not generic anymore, but x86-specific * All (?) archs should be able to use generic pci_iounmap() I've been looking into GENERIC_IOMAP a bit and am unsure whether that's true. Notably, powerpc seems to do something with it; see platforms/Kconfig: config PPC_INDIRECT_PIO bool select GENERIC_IOMAP I've had a few ideas, but don't really want to pursue them until we had a discussion about it: 1. If GENERIC_IOMAP is really x86-specific, that should mean that we could move lib/iomap.c to x86 completely, since that file is only built when that symbol is defined. 2. If it's moved to x86, the question arises whether it's possible to provide exact variants for lib/iomap.c's PIO_* constants. The comment above them in that file hint at those being just rough estimates ("assuming that all the low addresses are always PIO"). 3. To really just have one pci_iounmap(), we'd have to jump into s390 and replace its pci_iounmap(), which might be a bad idea since it also has its own pci_iomap(). So my tendency would be to leave s390 alone, figure out what's going on with powerpc and then, if possible, move lib/iomap.c to x86 and consequently have the second "generic" definition of iomem_is_ioport() from asm-generic/iomap.h removed. Ideas? P. [1] https://lore.kernel.org/all/20231213104922.13894-1-pstanner@redhat.com/ [2] https://lore.kernel.org/all/619ea619-29e4-42fb-9b27-1d1a32e0ee66@app.fastma…

[PATCH v5 0/5] Regather scattered PCI-Code

by Philipp Stanner

@Stable-Kernel: You receive this patch series because its first patch fixes leaks in PCI. Changes in v5: - Add forgotten update to MAINTAINERS file. Changes in v4: - Apply Arnd's Reviewed-by's - Add ifdef CONFIG_HAS_IOPORT_MAP guard in drivers/pci/iomap.c (build error on openrisc) - Fix typo in patch no.5 Changes in v3: - Create a separate patch for the leaks in lib/iomap.c. Make it the series' first patch. (Arnd) - Turns out the aforementioned bug wasn't just accidentally removing iounmap() with the ifdef, it was also missing ioport_unmap() to begin with. Add it. - Move the ARCH_WANTS_GENERIC_IOMEM_IS_IOPORT-mechanism from asm-generic/io.h to asm-generic/ioport.h. (Arnd) - Adjust the implementation of iomem_is_ioport() in asm-generic/io.h so that it matches exactly what pci_iounmap() previously did in lib/pci_iomap.c. (Arnd) - Move the CONFIG_HAS_IOPORT guard in asm-generic/io.h so that iomem_is_ioport() will always be compiled and just returns false if there are no ports. - Add TODOs to several places informing about the generic iomem_is_ioport() in lib/iomap.c not being generic. - Add TODO about the followup work to make drivers/pci/iomap.c's pci_iounmap() actually generic. Changes in v2: - Replace patch 4, previously extending the comment about pci_iounmap() in lib/iomap.c, with a patch that moves pci_iounmap() from that file to drivers/pci/iomap.c, creating a unified version there. (Arnd) - Implement iomem_is_ioport() as a new helper in asm-generic/io.h and lib/iomap.c. (Arnd) - Move the build rule in drivers/pci/Makefile for iomap.o under the guard of #if PCI. This had to be done because when just checking for GENERIC_PCI_IOMAP being defined, the functions don't disappear, which was the case previously in lib/pci_iomap.c, where the entire file was made empty if PCI was not set by the guard #ifdef PCI. (Intel's Bots) - Rephares all patches' commit messages a little bit. Sooooooooo. I reworked v1. Please review this carefully, the IO-Ranges are obviously a bit tricky, as is the build-system / ifdef-ery. Arnd has suggested that architectures defining a custom inb() need their own iomem_is_ioport(), as well. I've grepped for inb() and found the following list of archs that define their own: - alpha - arm - m68k <-- - parisc - powerpc - sh - sparc - x86 <-- All of those have their own definitons of pci_iounmap(). Therefore, they don't need our generic version in the first place and, thus, also need no iomem_is_ioport(). The two exceptions are x86 and m68k. The former uses lib/iomap.c through CONFIG_GENERIC_IOMAP, as Arnd pointed out in the previous discussion (thus, CONFIG_GENERIC_IOMAP is not really generic in this regard). So as I see it, only m68k WOULD need its own custom definition of iomem_is_ioport(). But as I understand it it doesn't because it uses the one from asm-generic/pci_iomap.h ?? I wasn't entirely sure how to deal with the address ranges for the generic implementation in asm-generic/io.h. It's marked with a TODO. Input appreciated. I removed the guard around define pci_iounmap in asm-generic/io.h. An alternative would be to have it be guarded by CONFIG_GENERIC_IOMAP and CONFIG_GENERIC_PCI_IOMAP, both. Without such a guard, there is no collision however, because generic pci_iounmap() from drivers/pci/iomap.c will only get pulled in when CONFIG_GENERIC_PCI_IOMAP is actually set. I cross-built this for a variety of architectures, including the usual suspects (s390, m68k). So far successfully. But let's see what Intel's robots say :O P. Original cover letter: Hi! So it seems that since ca. 2007 the PCI code has been scattered a bit. PCI's devres code, which is only ever used by users of the entire PCI-subsystem anyways, resides in lib/devres.c and is guarded by an ifdef PCI, just as the content of lib/pci_iomap.c is. It, thus, seems reasonable to move all of that. As I were at it, I moved as much of the devres-specific code from pci.c to devres.c, too. The only exceptions are four functions that are currently difficult to move. More information about that can be read here [1]. I noticed these scattered files while working on (new) PCI-specific devres functions. If we can get this here merged, I'll soon send another patch series that addresses some API-inconsistencies and could move the devres-part of the four remaining functions. I don't want to do that in this series as this here is only about moving code, whereas the next series would have to actually change API behavior. I successfully (cross-)built this for x86, x86_64, AARCH64 and ARM (allyesconfig). I booted a kernel with it on x86_64, with a Fedora desktop environment as payload. The OS came up fine I hope this is OK. If we can get it in, we'd soon have a very consistent PCI API again. Regards, P.
