The domain ID allocator is currently protected by a spin_lock. However,
ida_alloc_range can potentially block if it needs to allocate memory to
grow its internal structures.
Replace the spin_lock with a mutex which allows sleep on block. Thus,
the memory allocation flags can be updated from GFP_ATOMIC to GFP_KERNEL
to allow blocking memory allocations if necessary.
Introduce a new mutex, did_lock, specifically for protecting the domain
ida. The existing spinlock will remain for protecting other intel_iommu
fields.

Switch the intel iommu driver to use the ida mechanism for managing domain
IDs, replacing the previous fixed-size bitmap.
The previous approach allocated a bitmap large enough to cover the maximum
number of domain IDs supported by the hardware, regardless of the actual
number of domains in use. This led to unnecessary memory consumption,
especially on systems supporting a large number of iommu units but only
utilizing a small number of domain IDs.
The ida allocator dynamically manages the allocation and freeing of integer
IDs, only consuming memory for the IDs that are currently in use. This
significantly optimizes memory usage compared to the fixed-size bitmap.

VT-D HW can do WO permissions on the second-stage but not the first-stage
page table formats. The commit eea53c5816 ("iommu/vt-d: Remove WO
permissions on second-level paging entries") wanted to make this uniform
for VT-D by disabling the support for WO permissions in the second-stage.
This isn't consistent with how other drivers are working. Instead if the
underlying HW can support WO, it should. For instance AMD already supports
WO on its second stage (v1) format and not its first (v2).
If WO support needs to be discoverable it should be done through an
iommu_domain capability flag.

To handle this case; while enumerating ACPI devices in
get_acpihid_device_id() count the number of matching ACPI devices with
a matching _HID. If there is exactly one _HID match then accept it even
if the UID doesn't match. Other operating systems allow this, but the

This should be clarified in future revisions of the spec. Output

New timestamping API was introduced in commit 66f7223039 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6.
It is time to convert the stmmac driver to the new API, so that
timestamping configuration can be removed from the ndo_eth_ioctl()
path completely.
The existing timestamping calls are guarded by netif_running(). For
stmmac_hwtstamp_get() that is probably unnecessary, since no hardware
access is performed. But for stmmac_hwtstamp_set() I've preserved it,
since at least some IPs probably need pm_runtime_resume_and_get() to
access registers, which is otherwise called by __stmmac_open().

Originally, MCC just took periodic NoA into account. When the connected GO
announces non-periodic NoA and GC side is during MCC, sometimes GC cannot
receive beacons well if the MCC scheduling conflicts with the non-periodic
NoA planning. After the loss exceeds the tolerable amount, beacon filter
will report connection loss. However, in this case, the loss is acceptable.
So now, MCC will calculate the range of non-periodic NoA. And then, don't
care beacon loss during the range.
Besides, rtw89_mcc_fill_role_limit() only makes sense for GC. Remove the

Each write takes 30 seconds to fail because that's the timeout currently
used for control messages in rtw_usb_write().
In this scenario the firmware download takes at least 2000 seconds.
Because this is done from the USB probe function, the long delay makes
other things in the system hang.
Reduce the timeout to 500 ms. This is the value used by the official USB
wifi drivers from Realtek.
Of course this only makes things hang for ~30 seconds instead of ~30
minutes. It doesn't fix the firmware download.
Tested with RTL8822CU, RTL8812BU, RTL8811CU, RTL8814AU, RTL8811AU,

RX tag is sequence number to ensure RX DMA is complete. On platform
Gigabyte X870 AORUS ELITE WIFI7, sometimes it needs longer retry times
to complete RX DMA, or driver throws warnings and connection drops:

rtw89_8922ae 0000:07:00.0: failed to update 163 RXBD info: -11

Due to mac80211 triggering the hardware to enter idle mode, it fails
to install WEP key causing connected station can't ping successfully.
Currently, it forces the hardware to leave idle mode before driver
adding WEP keys.
