Fixes for v6.9
Display:
- Fixes for PM refcount leak when DP goes to disconnected state and
also when link training fails. This is also one of the issues found
with the pm runtime series
- Add missing newlines to prints in msm_fb and msm_kms
- Change permissions of some dpu debugfs entries which write to const
data from catalog to read-only to avoid protection faults
- Fix the interface table for the catalog of X1E80100. This is an
important fix to bringup DP for X1E80100.
- Logging fix to print the callback symbol in the invalid IRQ message
case rather than printing when its known to be NULL.
- Bindings fix to add DP node as child of mdss for mdss node
- Minor typo fix in DP driver API which handles port status change
GPU:
- fix CHRASHDUMP_READ()
- fix HHB (highest bank bit) for a619 to fix UBWC corruption

Handle only bigjoiner masters in skl_commit_modeset_enables/disables,
slave crtcs should be handled by master hooks. Same for encoders.
That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave.
v2: - Moved skl_pfit_enable, intel_dsc_enable, intel_crtc_vblank_on to intel_enable_ddi,
so that it is now finally symmetrical with the disable case, because currently
for some weird reason we are calling those from skl_commit_modeset_enables, while
for the disable case those are called from the ddi disable hooks.
v3: - Create intel_ddi_enable_hdmi_or_sst symmetrical to
intel_ddi_post_disable_hdmi_or_sst and move it also under non-mst check.
v4: - Fix intel_enable_ddi sequence
- Call intel_crtc_update_active_timings for slave pipes as well
[v5: vsyrjala: Use the name 'pipe_crtc' for the per-pipe crtc pointer
Use consistent style and naming
Protect macro arguments properly
Drop superfluous changes to the modeset sequence,
this now follows the old non-joiner sequence 100%

Reorganize the crtc disable path to only deal with the
master pipes/transcoders in intel_old_crtc_state_disables()
and offload the handling of joined pipes to hsw_crtc_disable().
This makes the whole thing much more sensible since we can
actually control the order in which we do the per-pipe vs.
per-transcoder modeset steps.

intel_ddi_post_disable_hdmi_or_sst() by looping over all the

Extract the "not-MST" stuff from intel_ddi_post_disable() so that
the whole thing isn't so cluttered.
The bigjoiner slave handling was outside of the !MST check,
but it really should have been inside it as its the counterpart
to the master handling inside the check. So we pull that
in as well. There is no functional change here as we don't
currently support bigjoiner+MST anyway.
v2: Rebase
v3: Actually extract the slave code as claimed in
the commit message (presumably a rebase fail in v2)

Advertize more suitable cursor sizes via the new SIZE_HINTS
plane property.
We can't really enumerate all supported cursor sizes on
the platforms where the cursor height can vary freely, so
for simplicity we'll just expose all square+POT sizes between
each platform's min and max cursor limits.
Depending on the platform this will give us one of three
results:
- 64x64,128x128,256x256,512x512
- 64x64,128x128,256x256
- 64x64

Add a new immutable plane property by which a plane can advertise
a handful of recommended plane sizes. This would be mostly exposed
by cursor planes as a slightly more capable replacement for
the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare
a one size fits all limit for the whole device.
Currently eg. amdgpu/i915/nouveau just advertize the max cursor
size via the cursor size caps. But always using the max sized
cursor can waste a surprising amount of power, so a better
strategy is desirable.
Most other drivers don't specify any cursor size at all, in
which case the ioctl code just claims that 64x64 is a great
choice. Whether that is actually true is debatable.
A poll of various compositor developers informs us that
blindly probing with setcursor/atomic ioctl to determine
suitable cursor sizes is not acceptable, thus the
introduction of the new property to supplant the cursor
size caps. The compositor will now be free to select a
more optimal cursor size from the short list of options.
Note that the reported sizes (either via the property or the
caps) make no claims about things such as plane scaling. So
these things should only really be consulted for simple
"cursor like" use cases.

Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying
txn") introduced changes to how binder objects are copied. In doing so,
it unintentionally removed an offset alignment check done through calls
to binder_alloc_copy_from_buffer() -> check_buffer().
These calls were replaced in binder_get_object() with copy_from_user(),
so now an explicit offset alignment check is needed here. This avoids
later complications when unwinding the objects gets harder.
It is worth noting this check existed prior to commit 7a67a39320df
("binder: add function to copy binder object from buffer"), likely
removed due to redundancy at the time.

While vmk80xx does have endpoint checking implemented, some things
can fall through the cracks. Depending on the hardware model,
URBs can have either bulk or interrupt type, and current version
of vmk80xx_find_usb_endpoints() function does not take that fully
into account. While this warning does not seem to be too harmful,
at the very least it will crash systems with 'panic_on_warn' set on
them.
Fix the issue found by Syzkaller [1] by somewhat simplifying the
endpoint checking process with usb_find_common_endpoints() and
ensuring that only expected endpoint types are present.
This patch has not been tested on real hardware.

This reverts commit 058a38acba15fd8e7b262ec6e17c4204cb15f984.
It's not necessary to avoid a spinlock, a sleeping lock on PREEMPT_RT, in

The patch mentioned in the `Fixes` tag removed the explicit assignment
of tx_info->xdpf to NULL with the justification that there's no need
to set tx_info->xdpf to NULL and tx_info->num_of_bufs to 0 in case
of a mapping error. Both values won't be used once the mapping function
returns an error, and their values would be overridden by the next
transmitted packet.
While both values do indeed get overridden in the next transmission
call, the value of tx_info->xdpf is also used to check whether a TX
descriptor's transmission has been completed (i.e. a completion for it
was polled).
An example scenario:
1. Mapping failed, tx_info->xdpf wasn't set to NULL
2. A VF reset occurred leading to IO resource destruction and
a call to ena_free_tx_bufs() function
3. Although the descriptor whose mapping failed was freed by the
transmission function, it still passes the check
if (!tx_info->skb)
(skb and xdp_frame are in a union)
4. The xdp_frame associated with the descriptor is freed twice
This patch returns the assignment of NULL to tx_info->xdpf to make the
cleaning function knows that the descriptor is already freed.

ENA has two types of TX queues:
- queues which only process TX packets arriving from the network stack
- queues which only process TX packets forwarded to it by XDP_REDIRECT
or XDP_TX instructions
The ena_free_tx_bufs() cycles through all descriptors in a TX queue
and unmaps + frees every descriptor that hasn't been acknowledged yet
by the device (uncompleted TX transactions).
The function assumes that the processed TX queue is necessarily from
the first category listed above and ends up using napi_consume_skb()
for descriptors belonging to an XDP specific queue.
This patch solves a bug in which, in case of a VF reset, the
descriptors aren't freed correctly, leading to crashes.

Missing IO completions check is called every second (HZ jiffies).
This commit fixes several issues with this check:
1. Duplicate queues check:
Max of 4 queues are scanned on each check due to monitor budget.
Once reaching the budget, this check exits under the assumption that
the next check will continue to scan the remainder of the queues,
but in practice, next check will first scan the last already scanned
queue which is not necessary and may cause the full queue scan to
last a couple of seconds longer.
The fix is to start every check with the next queue to scan.
For example, on 8 IO queues:
Bug: [0,1,2,3], [3,4,5,6], [6,7]
Fix: [0,1,2,3], [4,5,6,7]
2. Unbalanced queues check:
In case the number of active IO queues is not a multiple of budget,
there will be checks which don't utilize the full budget
because the full scan exits when reaching the last queue id.
The fix is to run every TX completion check with exact queue budget
regardless of the queue id.
For example, on 7 IO queues:
Bug: [0,1,2,3], [4,5,6], [0,1,2,3]
Fix: [0,1,2,3], [4,5,6,0], [1,2,3,4]
The budget may be lowered in case the number of IO queues is less
than the budget (4) to make sure there are no duplicate queues on
the same check.
For example, on 3 IO queues:
Bug: [0,1,2,0], [1,2,0,1]
Fix: [0,1,2], [0,1,2]

Small unsigned types are promoted to larger signed types in
the case of multiplication, the result of which may overflow.
In case the result of such a multiplication has its MSB
turned on, it will be sign extended with '1's.
This changes the multiplication result.
Code example of the phenomenon:
-------------------------------
u16 x, y;
size_t z1, z2;
x = y = 0xffff;
printk("x=%x y=%x\n",x,y);
z1 = x*y;
z2 = (size_t)x*y;
printk("z1=%lx z2=%lx\n", z1, z2);
Output:
-------
x=ffff y=ffff
z1=fffffffffffe0001 z2=fffe0001
The expected result of ffff*ffff is fffe0001, and without the
explicit casting to avoid the unwanted sign extension we got
fffffffffffe0001.
This commit adds an explicit casting to avoid the sign extension
issue.

In Clause 5 of IEEE Std 802-2014, two sublayers of the data link layer
(DLL) of the Open Systems Interconnection basic reference model (OSI/RM)
are described; the medium access control (MAC) and logical link control
(LLC) sublayers. The MAC sublayer is the one facing the physical layer.
In 8.2 of IEEE Std 802.1Q-2022, the Bridge architecture is described. A
Bridge component comprises a MAC Relay Entity for interconnecting the Ports
of the Bridge, at least two Ports, and higher layer entities with at least
a Spanning Tree Protocol Entity included.
Each Bridge Port also functions as an end station and shall provide the MAC
Service to an LLC Entity. Each instance of the MAC Service is provided to a
distinct LLC Entity that supports protocol identification, multiplexing,
and demultiplexing, for protocol data unit (PDU) transmission and reception
by one or more higher layer entities.
It is described in 8.13.9 of IEEE Std 802.1Q-2022 that in a Bridge, the LLC
Entity associated with each Bridge Port is modeled as being directly
connected to the attached Local Area Network (LAN).
On the switch with CPU port architecture, CPU port functions as Management
Port, and the Management Port functionality is provided by software which
functions as an end station. Software is connected to an IEEE 802 LAN that
is wholly contained within the system that incorporates the Bridge.
Software provides access to the LLC Entity associated with each Bridge Port
by the value of the source port field on the special tag on the frame
received by software.
We call frames that carry control information to determine the active
topology and current extent of each Virtual Local Area Network (VLAN),
i.e., spanning tree or Shortest Path Bridging (SPB) and Multiple VLAN
Registration Protocol Data Units (MVRPDUs), and frames from other link
constrained protocols, such as Extensible Authentication Protocol over LAN
(EAPOL) and Link Layer Discovery Protocol (LLDP), link-local frames. They
are not forwarded by a Bridge. Permanently configured entries in the
filtering database (FDB) ensure that such frames are discarded by the
Forwarding Process. In 8.6.3 of IEEE Std 802.1Q-2022, this is described in
detail:
Each of the reserved MAC addresses specified in Table 8-1
(01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]) shall be
permanently configured in the FDB in C-VLAN components and ERs.
Each of the reserved MAC addresses specified in Table 8-2
(01-80-C2-00-00-[01,02,03,04,05,06,07,08,09,0A,0E]) shall be permanently
configured in the FDB in S-VLAN components.
Each of the reserved MAC addresses specified in Table 8-3
(01-80-C2-00-00-[01,02,04,0E]) shall be permanently configured in the FDB
in TPMR components.
The FDB entries for reserved MAC addresses shall specify filtering for all
Bridge Ports and all VIDs. Management shall not provide the capability to
modify or remove entries for reserved MAC addresses.
The addresses in Table 8-1, Table 8-2, and Table 8-3 determine the scope of
propagation of PDUs within a Bridged Network, as follows:
The Nearest Bridge group address (01-80-C2-00-00-0E) is an address that
no conformant Two-Port MAC Relay (TPMR) component, Service VLAN (S-VLAN)
component, Customer VLAN (C-VLAN) component, or MAC Bridge can forward.
PDUs transmitted using this destination address, or any other addresses
that appear in Table 8-1, Table 8-2, and Table 8-3
(01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]), can
therefore travel no further than those stations that can be reached via a
single individual LAN from the originating station.
The Nearest non-TPMR Bridge group address (01-80-C2-00-00-03), is an
address that no conformant S-VLAN component, C-VLAN component, or MAC
Bridge can forward; however, this address is relayed by a TPMR component.
PDUs using this destination address, or any of the other addresses that
appear in both Table 8-1 and Table 8-2 but not in Table 8-3
(01-80-C2-00-00-[00,03,05,06,07,08,09,0A,0B,0C,0D,0F]), will be relayed
by any TPMRs but will propagate no further than the nearest S-VLAN
component, C-VLAN component, or MAC Bridge.
The Nearest Customer Bridge group address (01-80-C2-00-00-00) is an
address that no conformant C-VLAN component, MAC Bridge can forward;
however, it is relayed by TPMR components and S-VLAN components. PDUs
using this destination address, or any of the other addresses that appear
in Table 8-1 but not in either Table 8-2 or Table 8-3
(01-80-C2-00-00-[00,0B,0C,0D,0F]), will be relayed by TPMR components and
S-VLAN components but will propagate no further than the nearest C-VLAN
component or MAC Bridge.
Because the LLC Entity associated with each Bridge Port is provided via CPU
port, we must not filter these frames but forward them to CPU port.
In a Bridge, the transmission Port is majorly decided by ingress and egress
rules, FDB, and spanning tree Port State functions of the Forwarding
Process. For link-local frames, only CPU port should be designated as
destination port in the FDB, and the other functions of the Forwarding
Process must not interfere with the decision of the transmission Port. We
call this process trapping frames to CPU port.
Therefore, on the switch with CPU port architecture, link-local frames must
be trapped to CPU port, and certain link-local frames received by a Port of
a Bridge comprising a TPMR component or an S-VLAN component must be
excluded from it.
A Bridge of the switch with CPU port architecture cannot comprise a
Two-Port MAC Relay (TPMR) component as a TPMR component supports only a
subset of the functionality of a MAC Bridge. A Bridge comprising two Ports
(Management Port doesn't count) of this architecture will either function
as a standard MAC Bridge or a standard VLAN Bridge.
Therefore, a Bridge of this architecture can only comprise S-VLAN
components, C-VLAN components, or MAC Bridge components. Since there's no
TPMR component, we don't need to relay PDUs using the destination addresses
specified on the Nearest non-TPMR section, and the proportion of the
Nearest Customer Bridge section where they must be relayed by TPMR
components.
One option to trap link-local frames to CPU port is to add static FDB
entries with CPU port designated as destination port. However, because that
Independent VLAN Learning (IVL) is being used on every VID, each entry only
applies to a single VLAN Identifier (VID). For a Bridge comprising a MAC
Bridge component or a C-VLAN component, there would have to be 16 times
4096 entries. This switch intellectual property can only hold a maximum of
2048 entries. Using this option, there also isn't a mechanism to prevent
link-local frames from being discarded when the spanning tree Port State of
the reception Port is discarding.
The remaining option is to utilise the BPC, RGAC1, RGAC2, RGAC3, and RGAC4
registers. Whilst this applies to every VID, it doesn't contain all of the
reserved MAC addresses without affecting the remaining Standard Group MAC
Addresses. The REV_UN frame tag utilised using the RGAC4 register covers
the remaining 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] destination
addresses. It also includes the 01-80-C2-00-00-22 to 01-80-C2-00-00-FF
destination addresses which may be relayed by MAC Bridges or VLAN Bridges.
The latter option provides better but not complete conformance.
This switch intellectual property also does not provide a mechanism to trap
link-local frames with specific destination addresses to CPU port by
Bridge, to conform to the filtering rules for the distinct Bridge
components.
Therefore, regardless of the type of the Bridge component, link-local
frames with these destination addresses will be trapped to CPU port:
01-80-C2-00-00-[00,01,02,03,0E]
In a Bridge comprising a MAC Bridge component or a C-VLAN component:
Link-local frames with these destination addresses won't be trapped to
CPU port which won't conform to IEEE Std 802.1Q-2022:
01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F]
In a Bridge comprising an S-VLAN component:
Link-local frames with these destination addresses will be trapped to CPU
port which won't conform to IEEE Std 802.1Q-2022:
01-80-C2-00-00-00
Link-local frames with these destination addresses won't be trapped to
CPU port which won't conform to IEEE Std 802.1Q-2022:
01-80-C2-00-00-[04,05,06,07,08,09,0A]
Currently on this switch intellectual property, if the spanning tree Port
State of the reception Port is discarding, link-local frames will be
discarded.
To trap link-local frames regardless of the spanning tree Port State, make
the switch regard them as Bridge Protocol Data Units (BPDUs). This switch
intellectual property only lets the frames regarded as BPDUs bypass the
spanning tree Port State function of the Forwarding Process.
With this change, the only remaining interference is the ingress rules.
When the reception Port has no PVID assigned on software, VLAN-untagged
frames won't be allowed in. There doesn't seem to be a mechanism on the
switch intellectual property to have link-local frames bypass this function
of the Forwarding Process.

port 2 of the MT7988 SoC works.

mt8183-mfgcfg has a mutual dependency with genpd during the probing
stage, which leads to a deadlock in the following call stack:
CPU0: genpd_lock --> clk_prepare_lock
genpd_power_off_work_fn()
genpd_lock()
generic_pm_domain::power_off()
clk_unprepare()
clk_prepare_lock()
CPU1: clk_prepare_lock --> genpd_lock
clk_register()
__clk_core_init()
clk_prepare_lock()
clk_pm_runtime_get()
genpd_lock()
Do a runtime PM get at the probe function to make sure clk_register()
won't acquire the genpd lock. Instead of only modifying mt8183-mfgcfg,
do this on all mediatek clock controller probings because we don't
believe this would cause any regression.
Verified on MT8183 and MT8192 Chromebooks.
