Fwd: System (Xeon Nvidia) hangs at boot terminal after kernel 6.4.7

by Bagas Sanjaya

Hi, I notice a regression report on Bugzilla [1]. Quoting from it: > Kernel 6.4.6 compiled from source worked AOK on my desktop with Intel Xeon cpu and Nvidia graphics - see below for system specs. > > Kernels 6.4.7 & 6.4.8 also compiled from source with identical configs hang with a frozen boot terminal screen after a significant way through the boot sequence (e.g. whilst running /etc/profile). The system may still be running as a sound is emitted when the power button is pressed (only way to escape from the system hang). > > The issue seems to be specific to the hardware of this desktop as the problem kernels do boot through to completion on other machines. > > A test was done with a different build (from Porteus) of kernel 6.5-RC4 and that did not hang - but kernel 6.4.7 from the same builder hung just like my build. > > I apologise that I cannot provide any detailed diagnostics - but I can put diagnostics into /etc/profile and provide screenshots if requested. > > Forum thread with more details and screenshots: > https://forum.puppylinux.com/viewtopic.php?p=95733#p95733 > > Computer Profile: > Machine Dell Inc. Precision WorkStation T5400 (version: Not Specified) > Mainboard Dell Inc. 0RW203 (version: NA) > • BIOS Dell Inc.

FYI, this is stable-specific regression since it doesn't appear on mainline. Also, I have asked the reporter to also open the issue on gitlab.freedesktop.org tracker (as it is the standard for DRM subsystem). To the reporter (on To: list): It'd been great if you also have netconsole output on your Bugzilla report, providing that you have another machine connecting to your problematic one. Anyway, I'm adding this regression to be tracked by regzbot: #regzbot introduced: v6.4.6..v6.4.7 https://bugzilla.kernel.org/show_bug.cgi?id=217776 #regzbot link: https://forum.puppylinux.com/viewtopic.php?p=95733#p95733 Thanks.

[PATCH v2 0/3] cpufreq: Add basic cpufreq scaling for Qualcomm MSM8909

by Stephan Gerhold

Add the necessary definitions to the qcom-cpufreq-nvmem driver to support basic cpufreq scaling on the Qualcomm MSM8909 SoC. In practice the necessary power domains vary depending on the actual PMIC the SoC was combined with. With PM8909 the VDD_APC power domain is shared with VDD_CX so the RPM firmware handles all voltage adjustments, while with PM8916 and PM660 Linux is responsible to do adaptive voltage scaling of a dedicated CPU regulator using CPR. Signed-off-by: Stephan Gerhold <stephan.gerhold(a)kernkonzept.com> --- Changes in v2: - Reword commit messages based on discussion with Uffe - Use generic power domain name "perf" (Uffe) - Fix pm_runtime error handling (Uffe) - Add allocation cleanup patch as preparation - Fix ordering of qcom,msm8909 compatible (Konrad) - cpufreq-dt-platdev blocklist/dt-bindings patches were applied already - Link to v1: https://lore.kernel.org/r/20230912-msm8909-cpufreq-v1-0-767ce66b544b@kernko… --- Stephan Gerhold (3): cpufreq: qcom-nvmem: Simplify driver data allocation cpufreq: qcom-nvmem: Enable virtual power domain devices cpufreq: qcom-nvmem: Add MSM8909 drivers/cpufreq/qcom-cpufreq-nvmem.c | 124 +++++++++++++++++++++++++---------- 1 file changed, 90 insertions(+), 34 deletions(-) --- base-commit: 2e12b516f5e6046ceabd4d24e24297e4d130b148 change-id: 20230906-msm8909-cpufreq-dff238de9ff3 Best regards, -- Stephan Gerhold <stephan.gerhold(a)kernkonzept.com> Kernkonzept GmbH at Dresden, Germany, HRB 31129, CEO Dr.-Ing.

[PATCH v2] coresight: etm4x: Fix width of CCITMIN field

by James Clark

CCITMIN is a 12 bit field and doesn't fit in a u8, so extend it to u16. This probably wasn't an issue previously because values higher than 255 never occurred. But since commit 0f55b43dedcd ("coresight: etm: Override TRCIDR3.CCITMIN on errata affected cpus"), a comparison with 256 was done to enable the errata, generating the following W=1 build error: coresight-etm4x-core.c:1188:24: error: result of comparison of constant 256 with expression of type 'u8' (aka 'unsigned char') is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (drvdata->ccitmin == 256) Cc: stable(a)vger.kernel.org Fixes: 2e1cdfe184b5 ("coresight-etm4x: Adding CoreSight ETM4x driver") Reviewed-by: Mike Leach <mike.leach(a)linaro.org> Signed-off-by: James Clark <james.clark(a)arm.com> --- Changes since V1: * Change the fixes commit to the original addition of ccitmin, rather than the last refactor of the struct. drivers/hwtracing/coresight/coresight-etm4x.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/hwtracing/coresight/coresight-etm4x.h b/drivers/hwtracing/coresight/coresight-etm4x.h index 20e2e4cb7614..da17b6c49b0f 100644 --- a/drivers/hwtracing/coresight/coresight-etm4x.h +++ b/drivers/hwtracing/coresight/coresight-etm4x.h @@ -1036,7 +1036,7 @@ struct etmv4_drvdata { u8 ctxid_size; u8 vmid_size; u8 ccsize; - u8 ccitmin; + u16 ccitmin; u8 s_ex_level; u8 ns_ex_level; u8 q_support; -- 2.34.1

[PATCH v5 1/7] eventfs: Remove "is_freed" union with rcu head

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> The eventfs_inode->is_freed was a union with the rcu_head with the assumption that when it was on the srcu list the head would contain a pointer which would make "is_freed" true. But that was a wrong assumption as the rcu head is a single link list where the last element is NULL. Instead, split the nr_entries integer so that "is_freed" is one bit and the nr_entries is the next 31 bits. As there shouldn't be more than 10 (currently there's at most 5 to 7 depending on the config), this should not be a problem.

So take advantage of a recent fix for arm64 reported in [1] which introduces the size of the mapping as an argument of set_huge_pte_at(): we can then use this size to compute the number of page table entries to set for a NAPOT region.
