platform/mellanox: fix potential race in mlxbf-tmfifo driver

2023-06-09T08:48:00+00:00

[ Upstream commit 3d43f9f639542fadfb28f40b509bf147a6624d48 ]

This commit adds memory barrier for the 'vq' update in function
mlxbf_tmfifo_virtio_find_vqs() to avoid potential race due to
out-of-order memory write. It also adds barrier for the 'is_ready'
flag to make sure the initializations are visible before this flag
is checked.

platform/x86: intel_scu_pcidrv: Add back PCI ID for Medfield

2023-06-09T08:48:00+00:00

[ Upstream commit 4a9b6850c794e4394cad99e2b863d75f5bc8e92f ]

This id was removed in commit b47018a778c1 ("platform/x86: intel_scu_ipc:
Remove Lincroft support"), saying it is only used on Moorestown,
but apparently the same id is also used on Medfield.

Tested on the Medfield based Motorola RAZR i smartphone.

platform/x86/amd/pmf: Fix CnQF and auto-mode after resume

2023-06-05T07:29:30+00:00

[ Upstream commit b54147fa374dbeadcb01b1762db1a793e06e37de ]

After suspend/resume cycle there is an error message and auto-mode
or CnQF stops working.

[ 5741.447511] amd-pmf AMDI0100:00: SMU cmd failed. err: 0xff

[ 5741.447540] amd-pmf AMDI0100:00: [AUTO_MODE] avg power: 0 mW mode: QUIET

This is because the DRAM address used for accessing metrics table
needs to be refreshed after a suspend resume cycle. Add a resume
callback to reset this again.

commit 95e4b25192e9238fd2dbe85d96dd2f8fd1ce9d14 upstream.

platform/x86: ISST: Remove 8 socket limit

2023-05-30T13:17:26+00:00

commit bbb320bfe2c3e9740fe89cfa0a7089b4e8bfc4ff upstream.

Stop restricting the PCI search to a range of PCI domains fed to
pci_get_domain_bus_and_slot().  Instead, use for_each_pci_dev() and
look at all PCI domains in one pass.

On systems with more than 8 sockets, this avoids error messages like
"Information: Invalid level, Can't get TDP control information at
specified levels on cpu 480" from the intel speed select utility.

platform/x86/intel/ifs: Annotate work queue on stack so object debug does not complain

platform/x86: x86-android-tablets: Add Acer Iconia One 7 B1-750 data

2023-05-24T16:30:01+00:00

[ Upstream commit 2f0cf1e85ddb5ae17284050dc1adafb89e4f1d8f ]

The Acer Iconia One 7 B1-750 is a x86 ACPI tablet which ships with Android
x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there, causing various resource conflicts. Enumeration of these
is skipped through the acpi_quirk_skip_i2c_client_enumeration().

Add support for manually instantiating the I2C + other devices which are
actually present on this tablet by adding the necessary device info to
the x86-android-tablets module.

platform/x86: thinkpad_acpi: Add profile force ability

2023-05-17T12:01:54+00:00

commit 1684878952929e20a864af5df7b498941c750f45 upstream.

There has been a lot of confusion around which platform profiles are
supported on various platforms and it would be useful to have a debug
method to be able to override the profile mode that is selected.

I don't expect this to be used in anything other than debugging in
conjunction with Lenovo engineers - but it does give a way to get a
system working whilst we wait for either FW fixes, or a driver fix
to land upstream, if something is wonky in the mode detection logic
