x86_platform_for_v5.11

c9624cb7 · x86/platform/uv: Update sysfs documentation · Dec 07, 2020

- Add a new uv_sysfs driver and expose read-only information from UV BIOS
(Justin Ernst and Mike Travis)

- The usual set of small fixes.

x86_cpu_for_v5.11

262bd572 · x86/cpu/amd: Remove dead code for TSEG region remapping · Dec 08, 2020

- Save the AMD's physical die ID into cpuinfo_x86.cpu_die_id and convert all
code to use it (Yazen Ghannam)

- Remove a dead and unused TSEG region remapping workaround on AMD (Arvind Sankar)

x86_misc_for_v5.11

f77f420d · x86/msr: Add a pointer to an URL which contains further details · Dec 08, 2020

The main part of this branch is the ongoing fight against windmills in
an attempt to have userspace tools not poke at naked MSRs. This round
deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct poking into it
by our in-tree tools in favor of the proper "energy_perf_bias" sysfs
interface which we already have.

In addition, the msr.ko write filtering's error message points to a new
summary page which contains the info we collected from helpful reporters
about which userspace tools write MSRs:

  https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about

along with the current status of their conversion.

Rest is the usual small fixes and improvements.

x86_mm_for_v5.11

1fcd0091 · x86/mm/ident_map: Check for errors from ident_pud_init() · Oct 28, 2020
```
- A single improvement to check ident_pud_init()'s return value (Arvind Sankar)
```

x86_sgx_for_v5.11

a4b9c48b · x86/sgx: Return -EINVAL on a zero length buffer in sgx_ioc_enclave_add_pages() · Dec 03, 2020

"Intel SGX is new hardware functionality that can be used by
applications to populate protected regions of user code and data called
enclaves. Once activated, the new hardware protects enclave code and
data from outside access and modification.

Enclaves provide a place to store secrets and process data with those
secrets. SGX has been used, for example, to decrypt video without
exposing the decryption keys to nosy debuggers that might be used to
subvert DRM. Software has generally been rewritten specifically to
run in enclaves, but there are also projects that try to run limited
unmodified software in enclaves."

Most of the functionality is concentrated into arch/x86/kernel/cpu/sgx/
except the addition of a new mprotect() hook to control enclave page
permissions and support for vDSO exceptions fixup which will is used by
SGX enclaves.

All this work by Sean Christopherson, Jarkko Sakkinen and many others.

x86_microcode_update_for_v5.11

- Pass error records logged by firmware through the MCE decoding chain
  to provide human-readable error descriptions instead of raw values
  (Smita Koralahalli)

- Some #MC handler fixes (Gabriele Paoloni)

- The usual small fixes and cleanups all over.

2020-12-14:
- rebased on top of v5.10
- added patch to chnage Vbus hold voltage to 4.5V on Pinephone (this makes PD charging more stable)
2020-12-11:
- rebased on top of linus/master
2020-12-07:
- rebased on top of 5.10-rc7
2020-12-05:
- modem power driver: add more powerup modes and change interface for dumb and fastboot powerup
  - you can now write 2, 3 or 4 to .../powered sysfs file to select differnt powerup mode from
    the normal one (1)
  - this is useful for selecting alternate userspace configurations early in boot to allow
    tracing the userspace processes from early on for reverse engineering, and in the near
    future, it will be used to switch between original and fully-FOSS userspace code
    running on the modem's APPS CPU on powerup
    - see https://xnux.eu/log/#028
2020-12-02:
- fix WiFi blocking suspend
- improve modem power driver interaction with kernel's autosleep
- shorten resume times from 1.2s to 400ms (wifi driver optimization)
2020-11-30:
- I improved the anx7688 driver to actually respect PD capabilities of the source,
  and don't overload it. This should make it more likely to work with the USB-C
  docks when docks are powered.
- Pine64 dock can provide either 500mA when powered from regular USB-A charger
  (regardless of what kind of charger it is, it can't use more current from it)
- With my 3A PD charger, Pine64 dock will advertise 2600mA and Pinephone will
  now respect this limit.
- rebase on linus/master (5.10-rc6 atm)
- increase I2C clock for sensors and touchscreen/anx7688 from 100kHz to 400kHz
- added patch from https://patchwork.kernel.org/project/dri-devel/cover/20200222024210.18697-1-yuq825@gmail.com/#23237865
  for easier GPU debugging (suggested by bshah)
2020-11-28:
- rebased on linus/master
- replaced my 60FPS fix with a more mainlineable and better working solution from Roman Beranek
- disable 8723cs CONCURRENT_MODE, enable wifi 802.11z TDLS
2020-11-25:
- enable wifi power saving mode (saves 350mW in idle, and doesn't seem to break the wifi so far)
2020-11-25:
- added a new 2020-10 wifi driver and cleaned up to work with PinePhone
- see wifi-5.10 branch

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

x86-urgent-2020-12-13

0d07c0ec · x86/kprobes: Fix optprobe to detect INT3 padding correctly · Dec 12, 2020

A set of x86 and membarrier fixes:

  - Correct a few problems in the x86 and the generic membarrier
    implementation. Small corrections for assumptions about visibility
    which have turned out not to be true.

  - Make the PAT bits for memory encryption correct vs. 4K and 2M/1G page
    table entries as they are at a different location.

  - Fix a concurrency issue in the the local bandwidth readout of resource
    control leading to incorrect values

  - Fix the ordering of allocating a vector for an interrupt. The order
    missed to respect the provided cpumask when the first attempt of
    allocating node local in the mask fails. It then tries the node instead
    of trying the full provided mask first. This leads to erroneous error
    messages and breaking the (user) supplied affinity request. Reorder it.

  - Make the INT3 padding detection in optprobe work correctly.

xfs-5.11-merge-3

1189686e · fs/xfs: convert comma to semicolon · Dec 12, 2020

New code for 5.11:
- Introduce a "needsrepair" "feature" to flag a filesystem as needing a
  pass through xfs_repair.  This is key to enabling filesystem upgrades
  (in xfs_db) that require xfs_repair to make minor adjustments to metadata.
- Refactor parameter checking of recovered log intent items so that we
  actually use the same validation code as them that generate the intent
  items.
- Various fixes to online scrub not reacting correctly to directory
  entries pointing to inodes that cannot be igetted.
- Refactor validation helpers for data and rt volume extents.
- Refactor XFS_TRANS_DQ_DIRTY out of existence.
- Fix a longstanding bug where mounting with "uqnoenforce" would start
  user quotas in non-enforcing mode but /proc/mounts would display
  "usrquota", implying that they are being enforced.
- Don't flag dax+reflink inodes as corruption since that is a valid (but
  not fully functional) combination right now.
- Clean up raid stripe validation functions.
- Refactor the inode allocation code to be more straightforward.
- Small prep cleanup for idmapping support.
