The existing code derives the channel map used to program the HDaudio
link DMA from the hw_params, but that is not quite right in the case
of aggregation. The code in soc-pcm.c splits the hw_params depending
on the codec_ch_map, and we need to reconstruct the channel-map to
insert the data in the right places.
This issue is seen only on amplifier feedback capture where the data
from the second amplifier was replaced by that of the first amplifier.
Note that the loop iterator of the macro for_each_rtd_cpu_dais() is
reused in a following loop. This is different to all existing usages
of that macro, hence the use of a boolean flag to avoid an access to
an uninitialized variable.

There are bunch of codes in driver like
if (dma_set_mask_and_coherent(dev, DMA_BIT_MASK(64)))
dma_set_mask_and_coherent(dev, DMA_BIT_MASK(32))
Actually it is wrong because if dma_set_mask_and_coherent(64) fails,
dma_set_mask_and_coherent(32) will fail for the same reason.
And dma_set_mask_and_coherent(64) never returns failure.
According to the definition of dma_set_mask(), it indicates the width of
address that device DMA can access. If it can access 64-bit address, it
must access 32-bit address inherently. So only need set biggest address
width.
See below code fragment:
dma_set_mask(mask)
{
mask = (dma_addr_t)mask;
if (!dev->dma_mask || !dma_supported(dev, mask))
return -EIO;
arch_dma_set_mask(dev, mask);
*dev->dma_mask = mask;
return 0;
}
dma_supported() will call dma_direct_supported or iommux's dma_supported
call back function.
int dma_direct_supported(struct device *dev, u64 mask)
{
u64 min_mask = (max_pfn - 1) << PAGE_SHIFT;
/*
* Because 32-bit DMA masks are so common we expect every architecture
* to be able to satisfy them - either by not supporting more physical
* memory, or by providing a ZONE_DMA32. If neither is the case, the
* architecture needs to use an IOMMU instead of the direct mapping.
*/
if (mask >= DMA_BIT_MASK(32))
return 1;
...
}
The iommux's dma_supported() actually means iommu requires devices's
minimized dma capability.
An example:
static int sba_dma_supported( struct device *dev, u64 mask)()
{
...
* check if mask is >= than the current max IO Virt Address
* The max IO Virt address will *always* < 30 bits.
*/
return((int)(mask >= (ioc->ibase - 1 +
(ioc->pdir_size / sizeof(u64) * IOVP_SIZE) )));
...
}
1 means supported. 0 means unsupported.

When kmalloc_node() is called without __GFP_THISNODE and the target node
lacks sufficient memory, SLUB allocates a folio from a different node
other than the requested node, instead of taking a partial slab from it.
However, since the allocated folio does not belong to the requested
node, on the following allocation it is deactivated and added to the
partial slab list of the node it belongs to.
This behavior can result in excessive memory usage when the requested
node has insufficient memory, as SLUB will repeatedly allocate folios
from other nodes without reusing the previously allocated ones.
To prevent memory wastage, when a preferred node is indicated (not
NUMA_NO_NODE) but without a prior __GFP_THISNODE constraint:
1) try to get a partial slab from target node only by having
__GFP_THISNODE in pc.flags for get_partial()
2) if 1) failed, try to allocate a new slab from target node with
GFP_NOWAIT | __GFP_THISNODE opportunistically.
3) if 2) failed, retry with original gfpflags which will allow
get_partial() try partial lists of other nodes before potentially
allocating new page from other nodes
Without a preferred node, or with __GFP_THISNODE constraint, the
behavior remains unchanged.

Sometimes the readout of /sys/kernel/debug/swiotlb/io_tlb_used and
io_tlb_used_hiwater can be a huge number (e.g. 18446744073709551615),
which is actually a negative number if we use "%ld" to print the number.
When swiotlb_create_default_debugfs() is running from late_initcall,
mem->total_used may already be non-zero, because the storage driver
may have already started to perform I/O operations: if the storage
driver is built-in, its probe() callback is called before late_initcall.
swiotlb_create_debugfs_files() should not blindly set mem->total_used
and mem->used_hiwater to 0; actually it doesn't have to initialize the
fields at all, because the fields, as part of the global struct
io_tlb_default_mem, have been implicitly initialized to zero.
Also don't explicitly set mem->transient_nslabs to 0.

In current code, swiotlb_bounce() may do partial sync's correctly in
some circumstances, but may incorrectly fail in other circumstances.
The failure cases require both of these to be true:
1) swiotlb_align_offset() returns a non-zero "offset" value
2) the tlb_addr of the partial sync area points into the first
"offset" bytes of the _second_ or subsequent swiotlb slot allocated
for the mapping
Code added in commit 868c9ddc18 ("swiotlb: add overflow checks
to swiotlb_bounce") attempts to WARN on the invalid case where
tlb_addr points into the first "offset" bytes of the _first_
allocated slot. But there's no way for swiotlb_bounce() to distinguish
the first slot from the second and subsequent slots, so the WARN
can be triggered incorrectly when #2 above is true.
Related, current code calculates an adjustment to the orig_addr stored
in the swiotlb slot. The adjustment compensates for the difference
in the tlb_addr used for the partial sync vs. the tlb_addr for the full
mapping. The adjustment is stored in the local variable tlb_offset.
But when #1 and #2 above are true, it's valid for this adjustment to
be negative. In such case the arithmetic to adjust orig_addr produces
the wrong result due to tlb_offset being declared as unsigned.
Fix these problems by removing the over-constraining validations added
in 868c9ddc18. Change the declaration of tlb_offset to be signed
instead of unsigned so the adjustment arithmetic works correctly.
Tested with a test-only hack to how swiotlb_tbl_map_single() calls
swiotlb_bounce(). Instead of calling swiotlb_bounce() just once
for the entire mapped area, do a loop with each iteration doing
only a 128 byte partial sync until the entire mapped area is
sync'ed. Then with swiotlb=force on the kernel boot line, run a
variety of raw disk writes followed by read and verification of
all bytes of the written data. The storage device has DMA
min_align_mask set, and the writes are done with a variety of
original buffer memory address alignments and overall buffer
sizes. For many of the combinations, current code triggers the
WARN statements, or the data verification fails. With the fixes,
no WARNs occur and all verifications pass.

Allow a buffer pre-padding of up to alloc_align_mask, even if it requires
allocating additional IO TLB slots.
If the allocation alignment is bigger than IO_TLB_SIZE and min_align_mask
covers any non-zero bits in the original address between IO_TLB_SIZE and
alloc_align_mask, these bits are not preserved in the swiotlb buffer
address.
To fix this case, increase the allocation size and use a larger offset
within the allocated buffer. As a result, extra padding slots may be
allocated before the mapping start address.
Leave orig_addr in these padding slots initialized to INVALID_PHYS_ADDR.
These slots do not correspond to any CPU buffer, so attempts to sync the
data should be ignored.
The padding slots should be automatically released when the buffer is
unmapped. However, swiotlb_tbl_unmap_single() takes only the address of the
DMA buffer slot, not the first padding slot. Save the number of padding
slots in struct io_tlb_slot and use it to adjust the slot index in
swiotlb_release_slots(), so all allocated slots are properly freed.

limitations, which make up most of the queue limits, but it is wrong for
changes to the namespace configuration, where we do want to pick up the

+ rsnd_gen_regmap_init(..., 1, ..SDMC, conf_null);
Gen4 have only SSI0/SSIU0, we don't need to have multi channel settings.
- rsnd_gen_regmap_init(..., 10, ..SSI, ...);
+ rsnd_gen_regmap_init(..., 1, ..SSI, ...);
SSI_MODE2 address is different between Gen2/3 and Gen4, but it is not
used on Gen4. Thus we can share same regmap table.
Gen2/3 : 0x808
Gen4 : 0xa0c

Adds wrapper function snd_ctl_find_id_mixer_locked(). This is
identical to snd_ctl_find_id_mixer() except that it can be called
from code that is already holding controls_rwsem.

We got an error report about headphone type detection and button detection.
We fixed the headphone type detection error by adjusting the debounce timer
configuration. And we fixed the button detection error by disabling the
button detection feature when the headphone are unplugged and enabling it
when headphone are plugged in.

This patch improves the run-time calculation for program stats by
capturing the duration as soon as possible after the program returns.
Previously, the duration included u64_stats_t operations. While the
instrumentation overhead is part of the total time spent when stats are
enabled, distinguishing between the program's native execution time and
the time spent due to instrumentation is crucial for accurate
performance analysis.
By making this change, the patch facilitates more precise optimization
of BPF programs, enabling users to understand their performance in
environments without stats enabled.
I used a virtualized environment to measure the run-time over one minute
for a basic raw_tracepoint/sys_enter program, which just increments a
local counter. Although the virtualization introduced some performance
degradation that could affect the results, I observed approximately a
16% decrease in average run-time reported by stats with this change
(310 -> 260 nsec).

'no-emmc' is not a valid property.
The original intention was to use the 'no-mmc' property.
Change it accordingly to fix the following dt-schema warning:
imx7s-mba7.dtb: mmc@30b40000: Unevaluated properties are not allowed ('no-emmc' was unexpected)

This commit adds device tree support for the NXP S32G3-based
S32G-VNP-RDB3 Board [1].
The S32G3 features an 8-core ARM Cortex-A53 based SoC developed by NXP.
The device tree files are derived from the official NXP downstream
Linux tree [2].
This addition encompasses a limited selection of peripherals that
are upstream-supported. Apart from the ARM System Modules
(GIC, Generic Timer, etc.), the following IPs have been validated:
* UART: fsl-linflexuart
* SDHC: fsl-imx-esdhc
Clock settings for the chip rely on ATF Firmware [3].
Pin control integration into the device tree is pending and currently
relies on Firmware/U-Boot settings [4].
These changes were validated using BSP39 Firmware/U-Boot from NXP [5].
The modifications enable booting the official Ubuntu 22.04 from NXP on
the RDB3 with default settings from the SD card and eMMC.
