Since the wildcard at the end of OF module aliases is gone, autoloading
of modules that don't match a device's last (most generic) compatible
value fails.For example the CODA960 VPU on i.MX6Q has the SoC specific compatible
"fsl,imx6q-vpu" and the generic compatible "cnm,coda960". Since the
driver currently only works with knowledge about the SoC specific
integration, it doesn't list "cnm,cod960" in the module device table.This results in the device compatible
"of:NvpuTCfsl,imx6q-vpuCcnm,coda960" not matching the module alias
"of:N*T*Cfsl,imx6q-vpu" anymore, whereas before commit 2f632369ab79
("modpost: don't add a trailing wildcard for OF module aliases") it
matched the module alias "of:N*T*Cfsl,imx6q-vpu*".This patch adds two module aliases for each compatible, one without the
wildcard and one with "C*" appended.$ modinfo coda | grep imx6q
alias: of:N*T*Cfsl,imx6q-vpuC*
alias: of:N*T*Cfsl,imx6q-vpuFixes: 2f632369ab79 ("modpost: don't add a trailing wildcard for OF module aliases")

Commit ac551828993e ("modpost: i2c aliases need no trailing wildcard")
removed the wildcard at the end of the I2C module aliases because I2C
devices have no IDs so the aliases are just arbitrary device names.This is also true for OF modaliases since a compatible string is used to
define a specific IP hardware block. So the modalias should match a
specific compatible string and not attempt to match a compatible string
whose name matches the beginning of another one.For example, the following driver module:
$ modinfo cros_ec_keyb | grep alias
alias: platform:cros-ec-keyb
alias: of:N*T*Cgoogle,cros-ec-keyb*will be tried to be loaded for an alias of:N*T*Cgoogle,cros-ec-keyb-v2
but there could be a different driver that supports the device for that
compatible string so it's better to remove the trailing wildcard for OF.Also, remove the word "always" from the add_wildcard() function comment
since that was carried from the time where a wildcard was always added
at the end of the module alias for all the devices.Signed-off-by: Javier Martinez Canillas

Device drivers typically use ACPI _HIDs/_CIDs listed in struct device_driver
acpi_match_table to match devices. However, for generic drivers, we do not
want to list _HID for all supported devices. Also, certain classes of devices
do not have _CID (e.g. SATA, USB). Instead, we can leverage ACPI _CLS,
which specifies PCI-defined class code (i.e. base-class, subclass and
programming interface). This patch adds support for matching ACPI devices using
the _CLS method.To support loadable module, current design uses _HID or _CID to match device's
modalias. With the new way of matching with _CLS this would requires modification
to the current ACPI modalias key to include _CLS. This patch appends PCI-defined
class-code to the existing ACPI modalias as following.acpi::::..:::
E.g:
# cat /sys/devices/platform/AMDI0600:00/modalias
acpi:AMDI0600:010601:where bb is th base-class code, ss is te sub-class code, and pp is the
programming interface codeSince there would not be _HID/_CID in the ACPI matching table of the driver,
this patch adds a field to acpi_device_id to specify the matching _CLS.static const struct acpi_device_id ahci_acpi_match[] = {
{ ACPI_DEVICE_CLASS(PCI_CLASS_STORAGE_SATA_AHCI, 0xffffff) },
{},
};In this case, the corresponded entry in modules.alias file would be:
alias acpi*:010601:* ahci_platform

UTMI+ Low Pin Interface (ULPI) is a commonly used PHY
interface for USB 2.0. The ULPI specification describes a
standard set of registers which the vendors can extend for
their specific needs. ULPI PHYs provide often functions
such as charger detection and ADP sensing and probing.There are two major issues that the bus type is meant to
tackle:Firstly, ULPI registers are accessed from the controller.
The bus provides convenient method for the controller
drivers to share that access with the actual PHY drivers.Secondly, there are already platforms that assume ULPI PHYs
are runtime detected, such as many Intel Baytrail based
platforms. They do not provide any kind of hardware
description for the ULPI PHYs like separate ACPI device
object that could be used to enumerate a device from.Signed-off-by: Heikki Krogerus

Add MIPS Common Device Memory Map (CDMM) support in the form of a bus in
the standard Linux device model. Each device attached via CDMM is
discoverable via an 8-bit type identifier and may contain a number of
blocks of memory mapped registers in the CDMM region. IRQs are expected
to be handled separately.Due to the per-cpu (per-VPE for MT cores) nature of the CDMM devices,
all the driver callbacks take place from workqueues which are run on the
right CPU for the device in question, so that the driver doesn't need to
be as concerned about which CPU it is running on. Callbacks also exist
for when CPUs are taken offline, so that any per-CPU resources used by
the driver can be disabled so they don't get forcefully migrated. CDMM
devices are created as children of the CPU device they are attached to.Any existing CDMM configuration by the bootloader will be inherited,
however platforms wishing to enable CDMM should implement the weak
mips_cdmm_phys_base() function (see asm/cdmm.h) so that the bus driver
knows where it should put the CDMM region in the physical address space
if the bootloader hasn't already enabled it.A mips_cdmm_early_probe() function is also provided to allow early boot
or particularly low level code to set up the CDMM region and probe for a
specific device type, for example early console or KGDB IO drivers for
the EJTAG Fast Debug Channel (FDC) CDMM device.Signed-off-by: James Hogan

The x86 CPU feature modalias handling existed before it was reimplemented
generically. This patch aligns the x86 handling so that it
(a) reuses some more code that is now generic;
(b) uses the generic format for the modalias module metadata entry, i.e., it
now uses 'cpu:type:x86,venVVVVfamFFFFmodMMMM:feature:,XXXX,YYYY' instead of
the 'x86cpu:vendor:VVVV:family:FFFF:model:MMMM:feature:,XXXX,YYYY' that was
used before.Signed-off-by: Ard Biesheuvel

This patch adds support for advertising optional CPU features over udev
using the modalias, and for declaring compatibility with/dependency upon
such a feature in a module.The mapping between feature numbers and actual features should be provided
by the architecture in a file called which exports the
following functions/macros:
- cpu_feature(FEAT), a preprocessor macro that maps token FEAT to a
numeric index;
- bool cpu_have_feature(n), returning whether this CPU has support for
feature #n;
- MAX_CPU_FEATURES, an upper bound for 'n' in the previous function.The feature can then be enabled by setting CONFIG_GENERIC_CPU_AUTOPROBE
for the architecture.For instance, a module that registers its module init function using
module_cpu_feature_match(FEAT_X, module_init_function)
will be probed automatically when the CPU's support for the 'FEAT_X'
feature is advertised over udev, and will only allow the module to be
loaded by hand if the 'FEAT_X' feature is supported.Signed-off-by: Ard Biesheuvel

Commit afe2dab4f6 ("USB: add hex/bcd detection to usb modalias generation")
changed the routine that generates alias ranges. Before that change, only
digits 0-9 were supported; the commit tried to fix the case when the range
includes higher values than 0x9.Unfortunately, the commit didn't fix the case when the range includes both
0x9 and 0xA, meaning that the final range must look like [x-9A-y] where
x = 0xA -- instead the [x-9A-x] range was produced.Modprobe doesn't complain as it sees no difference between no-match and
bad-pattern results of fnmatch().Fixing this simple bug to fix the aliases.
Also changing the hardcoded beginning of the range to uppercase as all the
other letters are also uppercase in the device version numbers.Fortunately, this affects only the dvb-usb-dib0700 module, AFAIK.

HID devices are only partially presented to userland. Hotplugged
devices emit events containing a modalias based on the basic bus,

depend on details such as a single usb interface or a particular item
in a report descriptor.This patch adds a device group to the hid device id, and broadcasts it
using uevent and the device modalias. The module alias generation is
modified to match. As a consequence, a device with a non-zero group
will be processed by the corresponding group driver instead of by the
generic hid driver.Signed-off-by: Henrik Rydberg

Handling of isapnp module aliases was broken by commit
626596e295d477c0fefa08cd5daa7dd011b1bb2c by changing "isapnp" string to "isa".
The code was then modified by commit
e49ce14150c64b29a8dd211df785576fa19a9858 but this bug remained.Change the string back to "isapnp".

We currently include commas on both sides of the feature ID in a
modalias, but this prevents the lowest numbered feature of a CPU from
being matched. Since all feature IDs have the same length, we do not
need to worry about substring matches, so omit commas from the
modalias entirely.Avoid generating multiple adjacent wildcards when there is no
feature ID to match.Signed-off-by: Ben Hutchings

There's a growing number of drivers that support a specific x86 feature
or CPU. Currently loading these drivers currently on a generic
distribution requires various driver specific hacks and it often
doesn't work.This patch adds auto probing for drivers based on the x86 cpuid
information, in particular based on vendor/family/model number
and also based on CPUID feature bits.For example a common issue is not loading the SSE 4.2 accelerated
CRC module: this can significantly lower the performance of BTRFS
which relies on fast CRC.Another issue is loading the right CPUFREQ driver for the current CPU.
Currently distributions often try all all possible driver until
one sticks, which is not really a good way to do this.It works with existing udev without any changes. The code
exports the x86 information as a generic string in sysfs
that can be matched by udev's pattern matching.This scheme does not support numeric ranges, so if you want to
handle e.g. ranges of model numbers they have to be encoded
in ASCII or simply all models or families listed. Fixing
that would require changing udev.Another issue is that udev will happily load all drivers that match,
there is currently no nice way to stop a specific driver from
being loaded if it's not needed (e.g. if you don't need fast CRC)
But there are not that many cpu specific drivers around and they're
all not that bloated, so this isn't a particularly serious issue.Originally this patch added the modalias to the normal cpu
sysdevs. However sysdevs don't have all the infrastructure
needed for udev, so it couldn't really autoload drivers.
This patch instead adds the CPU modaliases to the cpuid devices,
which are real devices with full support for udev. This implies
that the cpuid driver has to be loaded to use this.This patch just adds infrastructure, some driver conversions
in followups.Thanks to Kay for helping with some sysfs magic.
v2: Constifcation, some updates
v4: (trenn@suse.de):
- Use kzalloc instead of kmalloc to terminate modalias buffer
- Use uppercase hex values to match correctly against hex values containing

This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7.
Conflicts:
scripts/mod/file2alias.c
This change is wrong on many levels. First and foremost, it causes a
regression. On boot on Assabet, which this patch gives a codec id of
'ucb1x00', it gives:ucb1x00 ID not found: 1005
0x1005 is a valid ID for the UCB1300 device.
Secondly, this patch is way over the top in terms of complexity. The
only device which has been seen to be connected with this MCP code is
the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same
driver. Adding a match table, requiring the codec string to match the
hardware ID read out of the ID register, etc is completely over the top
when we can just read the hardware ID register.
