platform/mellanox: mlxbf-pmc: fix sscanf() error checking

2023-05-30T13:17:27+00:00

commit 95e4b25192e9238fd2dbe85d96dd2f8fd1ce9d14 upstream.

The sscanf() function never returns negatives.  It returns the number of
items successfully read.

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/amd: pmc: Fix memory leak in amd_pmc_stb_debugfs_open_v2()

Function amd_pmc_stb_debugfs_open_v2() may be called when the STB
debug mechanism enabled.

When amd_pmc_send_cmd() fails, the 'buf' needs to be released.

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

platform/x86: thinkpad_acpi: Fix platform profiles on T490

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

commit 0c0cd3e25a5b64b541dd83ba6e032475a9d77432 upstream.

I had incorrectly thought that PSC profiles were not usable on Intel
platforms so had blocked them in the driver initialistion. This broke
platform profiles on the T490.

After discussion with the FW team PSC does work on Intel platforms and
should be allowed.

Note - it's possible this may impact other platforms where it is advertised
but special driver support that only Windows has is needed. But if it does
then they will need fixing via quirks. Please report any issues to me so I
can get them addressed - but I haven't found any problems in testing...yet
