2021-08-12x86/resctrl: Fix default monitoring groups reportingBabu Moger1-14/+13
Creating a new sub monitoring group in the root /sys/fs/resctrl leads to getting the "Unavailable" value for mbm_total_bytes and mbm_local_bytes on the entire filesystem. Steps to reproduce: 1. mount -t resctrl resctrl /sys/fs/resctrl/ 2. cd /sys/fs/resctrl/ 3. cat mon_data/mon_L3_00/mbm_total_bytes 23189832 4. Create sub monitor group: mkdir mon_groups/test1 5. cat mon_data/mon_L3_00/mbm_total_bytes Unavailable When a new monitoring group is created, a new RMID is assigned to the new group. But the RMID is not active yet. When the events are read on the new RMID, it is expected to report the status as "Unavailable". When the user reads the events on the default monitoring group with multiple subgroups, the events on all subgroups are consolidated together. Currently, if any of the RMID reads report as "Unavailable", then everything will be reported as "Unavailable". Fix the issue by discarding the "Unavailable" reads and reporting all the successful RMID reads. This is not a problem on Intel systems as Intel reports 0 on Inactive RMIDs.

2021-08-12powerpc/xive: Do not skip CPU-less nodes when creating the IPIsCédric Le Goater1-11/+24
On PowerVM, CPU-less nodes can be populated with hot-plugged CPUs at runtime. Today, the IPI is not created for such nodes, and hot-plugged CPUs use a bogus IPI, which leads to soft lockups. We can not directly allocate and request the IPI on demand because bringup_up() is called under the IRQ sparse lock. The alternative is to allocate the IPIs for all possible nodes at startup and to request the mapping on demand when the first CPU of a node is brought up.

2021-08-12x86/reboot: Limit Dell Optiplex 990 quirk to early BIOS versionsPaul Gortmaker1-1/+2
When this platform was relatively new in November 2011, with early BIOS revisions, a reboot quirk was added in commit 6be30bb7d750 ("x86/reboot: Blacklist Dell OptiPlex 990 known to require PCI reboot") However, this quirk (and several others) are open-ended to all BIOS versions and left no automatic expiry if/when the system BIOS fixed the issue, meaning that nobody is likely to come along and re-test. What is really problematic with using PCI reboot as this quirk does, is that it causes this platform to do a full power down, wait one second, and then power back on. This is less than ideal if one is using it for boot testing and/or bisecting kernels when legacy rotating hard disks are installed. It was only by chance that the quirk was noticed in dmesg - and when disabled it turned out that it wasn't required anymore (BIOS A24), and a default reboot would work fine without the "harshness" of power cycling the machine (and disks) down and up like the PCI reboot does. Doing a bit more research, it seems that the "newest" BIOS for which the issue was reported[1] was version A06, however Dell[2] seemed to suggest only up to and including version A05, with the A06 having a large number of fixes[3] listed. As is typical with a new platform, the initial BIOS updates come frequently and then taper off (and in this case, with a revival for CPU CVEs); a search for O990-A<ver>.exe reveals the following dates: A02 16 Mar 2011 A03 11 May 2011 A06 14 Sep 2011 A07 24 Oct 2011 A10 08 Dec 2011 A14 06 Sep 2012 A16 15 Oct 2012 A18 30 Sep 2013 A19 23 Sep 2015 A20 02 Jun 2017 A23 07 Mar 2018 A24 21 Aug 2018 While it's overkill to flash and test each of the above, it would seem likely that the issue was contained within A0x BIOS versions, given the dates above and the dates of issue reports[4] from distros. So rather than just throw out the quirk entirely, limit the scope to just those early BIOS versions, in case people are still running systems from 2011 with the original as-shipped early A0x BIOS versions.

2021-08-12riscv: Move early fdt mapping creation in its own functionAlexandre Ghiti1-36/+40
The code that handles the early fdt mapping is hard to read and does not create the same mapping size depending on the kernel: - for 64-bit, 2 PMD entries are used which amounts to a 4MB mapping - for 32-bit, 2 PGDIR entries are used which amounts to a 8MB mapping So keep using 2 PMD entries for 64-bit and use only one PGD entry for 32-bit needed to cover 4MB. Move that into a new function called create_fdt_early_page_table which, using the same naming as create_kernel_page_table.
