The size limit macros are located further down in printk.c and
behind ifdef conditionals. This complicates their usage for
upcoming changes. Move the macros into internal.h so that they
are still invisible outside of printk, but easily accessible
for printk.
Also, the maximum size of formatted extended messages does not
need to be known by any code outside of printk, so move it to
internal.h as well. And like CONSOLE_LOG_MAX, for !CONFIG_PRINTK
set CONSOLE_EXT_LOG_MAX to 0 to reduce the static memory
footprint.

The file locking definitions have lived in fs.h since the dawn of time,
but they are only used by a small subset of the source files that
include it.
Move the file locking definitions to a new header file, and add the
appropriate #include directives to the source files that need them. By
doing this we trim down fs.h a bit and limit the amount of rebuilding
that has to be done when we make changes to the file locking APIs.

mlx5-updates-2023-01-10
1) From Gal: Add debugfs entries for netdev nic driver
- ktls, flow steering and hairpin info
- useful for debug and performance analysis
- e.g hairpin queue attributes, dump ktls tx pool size, etc
2) From Maher: Update shared buffer configuration on PFC commands
2.1) For every change of buffer's headroom, recalculate the size of shared
buffer to be equal to "total_buffer_size" - "new_headroom_size".
The new shared buffer size will be split in ratio of 3:1 between
lossy and lossless pools, respectively.
2.2) For each port buffer change, count the number of lossless buffers.
If there is only one lossless buffer, then set its lossless pool
usage threshold to be infinite. Otherwise, if there is more than
one lossless buffer, set a usage threshold for each lossless buffer.
While at it, add more verbosity to debug prints when handling user
commands, to assist in future debug.
3) From Tariq: Throttle high rate FW commands
4) From Shay: Properly initialize management PF
5) Various cleanup patches

Certain connection-based device-offload protocols (like TLS) use
per-connection HW objects to track the state, maintain the context, and
perform the offload properly. Some of these objects are created,
modified, and destroyed via FW commands. Under high connection rate,
this type of FW commands might continuously populate all slots of the FW
command interface and throttle it, while starving other critical control
FW commands.
Limit these throttle commands to using only up to a portion (half) of
the FW command interface slots. FW commands maximal rate is not hit, and
the same high rate is still reached when applying this limitation.

Currently C22 and C45 transactions are mixed over a combined API calls
which make use of a special bit in the reg address to indicate if a
C45 transaction should be performed. This makes it impossible to know
if the bus driver actually supports C45. Additionally, many C22 only
drivers don't return -EOPNOTSUPP when asked to perform a C45
transaction, they mistaking perform a C22 transaction.
This is the first step to cleanly separate C22 from C45. To maintain
backwards compatibility until all drivers which are capable of
performing C45 are converted to this new API, the helper functions
will fall back to the older API if the new API is not
supported. Eventually this fallback will be removed.

ARM: SoC fixes
These are three fixes for mistakes I discovered during the preparation
of the boardfile removal. Robert noticed the accidental removal
of PXA310 and PXA320 support because of a misplaced Kconfig statement,
and the two OMAP patches were build failures that got introduced
earlier but that I found while testing the removal.
* 'armsoc-build-fixes' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
ARM: omap1: fix building gpio15xx
ARM: omap1: fix !ARCH_OMAP1_ANY link failures
ARM: pxa: enable PXA310/PXA320 for DT-only build
|
|
While compile-testing randconfig builds for the upcoming boardfile
removal, I noticed that an earlier patch of mine was completely
broken, and the introduction of CONFIG_ARCH_OMAP1_ANY only replaced
one set of build failures with another one, now resulting in
link failures like
ld: drivers/video/fbdev/omap/omapfb_main.o: in function `omapfb_do_probe':
drivers/video/fbdev/omap/omapfb_main.c:1703: undefined reference to `omap_set_dma_priority'
ld: drivers/dma/ti/omap-dma.o: in function `omap_dma_free_chan_resources':

drivers/usb/gadget/udc/omap_udc.c:820: undefined reference to `omap_get_dma_active_status'
I tried reworking it, but the resulting patch ended up much bigger than
simply avoiding the original problem of unused-function warnings like
arch/arm/mach-omap1/mcbsp.c:76:30: error: unused variable 'omap1_mcbsp_ops' [-Werror,-Wunused-variable]
As a result, revert the previous fix, and rearrange the code that
produces warnings to hide them. For mcbsp, the #ifdef check can
simply be removed as the cpu_is_omapxxx() checks already achieve
the same result, while in the io.c the easiest solution appears to
be to merge the common map bits into each soc specific portion.
This gets cleaned in a nicer way after omap7xx support gets dropped,
as the remaining SoCs all have the exact same I/O map.

Some genpd providers doesn't ensure that it has turned off at hardware.
This is fine until the consumer really requires during some special
scenarios that the power domain collapse at hardware before it is
turned ON again.
An example is the reset sequence of Adreno GPU which requires that the
'gpucc cx gdsc' power domain should move to OFF state in hardware at
least once before turning in ON again to clear the internal state.

There are unused clocks that need to remain untouched by clk_disable_unused,
and most likely could be disabled later on sync_state. So provide a generic
sync_state callback for the clock providers that register such clocks.
Then, use the same mechanism as clk_disable_unused from that generic
callback, but pass the device to make sure only the clocks belonging to
the current clock provider get disabled, if unused. Also, during the
default clk_disable_unused, if the driver that registered the clock has
the generic clk_sync_state_disable_unused callback set for sync_state,
skip disabling its clocks.

Until now, it is not possible for a PHY driver to disable interrupts
during runtime. If a driver offers the .config_intr() as well as the
.handle_interrupt() ops, it is eligible for interrupt handling.
Introduce a new flag for the dev_flags property of struct phy_device, which
can be set by PHY driver to skip interrupt setup and fall back to polling
mode.
At the moment, this is used for the MaxLinear PHY which has broken
interrupt handling and there is a need to disable interrupts in some

Make FS_IOC_ENABLE_VERITY support values of
fsverity_enable_arg::block_size other than PAGE_SIZE.
To make this possible, rework build_merkle_tree(), which was reading
data and hash pages from the file and assuming that they were the same
thing as "blocks".
For reading the data blocks, just replace the direct pagecache access
with __kernel_read(), to naturally read one block at a time.
(A disadvantage of the above is that we lose the two optimizations of
hashing the pagecache pages in-place and forcing the maximum readahead.
That shouldn't be very important, though.)
The hash block reads are a bit more difficult to handle, as the only way
to do them is through fsverity_operations::read_merkle_tree_page().
Instead, let's switch to the single-pass tree construction algorithm
that fsverity-utils uses. This eliminates the need to read back any
hash blocks while the tree is being built, at the small cost of an extra
block-sized memory buffer per Merkle tree level. This is probably what
I should have done originally.
Taken together, the above two changes result in page-size independent
code that is also a bit simpler than what we had before.

Add support for verifying data from verity files whose Merkle tree block
size is less than the page size. The main use case for this is to allow
a single Merkle tree block size to be used across all systems, so that
only one set of fsverity file digests and signatures is needed.
To do this, eliminate various assumptions that the Merkle tree block
size and the page size are the same:
- Make fsverity_verify_page() a wrapper around a new function
fsverity_verify_blocks() which verifies one or more blocks in a page.
- When a Merkle tree block is needed, get the corresponding page and
only verify and use the needed portion. (The Merkle tree continues to
be read and cached in page-sized chunks; that doesn't need to change.)
- When the Merkle tree block size and page size differ, use a bitmap
fsverity_info::hash_block_verified to keep track of which Merkle tree
blocks have been verified, as PageChecked cannot be used directly.

https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc into arm/soc
While going through the removal of board files on some other
platforms, I noticed a bit of outdated code on omap2+ that
was left behind after the platform became DT only.
This is a separate branch, to avoid conflicts with other omap2
changes.
* 'omap/omap2-cleanup' of https://git.kernel.org/pub/scm/linux/kernel/git/soc/soc:
ARM: omap2: make functions static
ARM: omap2: remove unused omap2_pm_init
ARM: omap2: remove unused declarations
ARM: omap2: remove unused functions
ARM: omap2: smartreflex: remove on_init control
ARM: omap2: remove APLL control
ARM: omap2: simplify clock2xxx header
ARM: omap2: remove unused omap_hwmod_reset.c
ARM: omap2: remove unused headers
ARM: omap2: remove unused USB code
ARM: remove CONFIG_UNUSED_BOARD_FILES

The current implementation of rtc-efi is expecting all the 4
time services GET{SET}_TIME{WAKEUP} must be supported by UEFI
firmware. As per the EFI_RT_PROPERTIES_TABLE, the platform
specific implementations can choose to enable selective time
services based on the RTC device capabilities.
This patch does the following changes to provide GET/SET RTC
services on platforms that do not support the WAKEUP feature.
1) Relax time services cap check when creating a platform device.
2) Clear RTC_FEATURE_ALARM bit in the absence of WAKEUP services.
3) Conditional alarm entries in '/proc/driver/rtc'.

Add the EC header changes need to support USB Type-C VDM (Vendor Defined
Messages) communication between the system and USB PD-enabled
peripherals.
The headers are already present in the EC code base, from which they've
been ported [1].

This reverts commit 66ee379d743c69c726b61d078119a34d5be96a35.
The feature flag introduced by Commit 66ee379d743c ("mfd: cros_ec: Add
SCP Core-1 as a new CrOS EC MCU") was not first added in the source EC
code base[1]. This can lead to the possible misinterpration of an EC's
supported feature set, as well as causes issues with all future feature
flag updates.

Provide stub functions when CONFIG_SOUNDWIRE is not set for functions
that are quite likely to be used from common code on devices supporting

The commit 167790abb90f ("soundwire: export sdw_write/read_no_pm
functions") exposed the single byte no_pm versions of the IO functions
that can be used without touching PM, export the multi byte no_pm
versions for the same reason.

The Device_ID registers already tell us if a device supports the SDCA
specification or not, in hindsight we never needed a property when the
information is reported by both hardware and ACPI.

The layout of perf_sample_data is designed to minimize cache-line
access. The perf_sample_data_init() used to initialize a couple of
fields unconditionally so they were placed together at the head.
But it's changed now to set the fields according to the actual
sample_type flags. The main user (the perf tools) sets the IP, TID,
TIME, PERIOD always. Also group relevant fields like addr, phys_addr
and data_page_size.

The macro PMU_FORMAT_ATTR facilitates the definition of both the "show"
function and "format_attr". But it only works for a non-hybrid platform.
For a hybrid platform, the name "format_attr_hybrid_" is used.
The definition of the "show" function can be shared between a non-hybrid
platform and a hybrid platform. Add a new macro PMU_FORMAT_ATTR_SHOW.
No functional change. The PMU_FORMAT_ATTR_SHOW will be used in the
following patch.
