This reverts commit 3cc67fe1b3aa1ac4720e002f2aa2d08c9199a584.
Some users have reported flickerng with S/G display. We've
tried extensively to reproduce and debug the issue on a wide
variety of platform configurations (DRAM bandwidth, etc.) and
a variety of monitors, but so far have not been able to. We
disabled S/G display on a number of platforms to address this
but that leads to failure to pin framebuffers errors and
blank displays when there is memory pressure or no displays
at all on systems with limited carveout (e.g., Chromebooks).
We have a parameter to disable this as a debugging option as a
way for users to disable this, depending on their use case,
and for us to help debug this further. Having this enabled
seems like the lesser of to evils.

While checking Pin Assignments of the port and partner during probe, we
don't take into account whether the peripheral is a plug or receptacle.
This manifests itself in a mode entry failure on certain docks and
dongles with captive cables. For instance, the Startech.com Type-C to DP
dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail
the Pin Assignment compatibility check, despite it supporting
Pin Assignment C as a UFP.
Update the check to use the correct DP Pin Assign macros that
take the peripheral's receptacle bit into account.

This reverts commit 321b59870f850a10dbb211ecd2bd87b41497ea6f.
This commit broke USB networking on Ingenic SoCs and maybe elsewhere.
The actual reason is unknown; and while a proper fix would be better,
we're sitting at -rc7 now, so a revert is justified - and we can work on
re-introducing this change for 6.3.

Commit 550b33cfd445 ("arm64: efi: Force the use of SetVirtualAddressMap()
on Altra machines") identifies the Altra family via the family field in
the type#1 SMBIOS record. eMAG and Altra Max machines are similarly
affected but not detected with the strict strcmp test.
The type1_family smbios string is not an entirely reliable means of
identifying systems with this issue as OEMs can, and do, use their own
strings for these fields. However, until we have a better solution,
capture the bulk of these systems by adding strcmp matching for "eMAG"
and "Altra Max".

So it's clear that something in the PTP RX trapping logic went wrong.
Looking a bit at the code, I can see that there are 4 typos, which
populate "ipv4" VCAP IS2 key filter fields for IPv6 keys.
VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are
handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at
&filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6.
Simply put, when we populate the wrong key field, &filter->key.ipv6
fields "proto.mask" and "proto.value" remain all zeroes (or "don't care").
So is2_entry_set() will enter the "else" of this "if" condition:
if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP))
and proceed to ignore the "proto" field. The resulting rule will match
on all IPv6 traffic, trapping it to the CPU.
This is the reason why the local_termination.sh selftest sees it,
because control traps are stronger than the PGID_MCIPV6 used for
flooding (from the forwarding data path).
But the problem is in fact much deeper. We trap all IPv6 traffic to the
CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software
forwarding will not take place and IPv6 traffic will never reach its
destination.
The fix is simple - correct the typos.
I was intentionally inaccurate in the commit message about the breakage
occurring when any PTP timestamping is enabled. In fact it only happens
when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or
HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX
timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT.
I wanted people skimming through git logs to not think that the bug
doesn't affect them because they only use ptp4l in L2 mode.

extreme reduced blanking
The formula that determines the core clock requirement based on pixel
clock and blanking has been determined experimentally to minimise the
clock while supporting all modes we've seen.
A new reduced blanking mode (4kp60 at 533MHz rather than the standard
594MHz) has been seen that doesn't produce a high enough clock and
results in "flip_done timed out" error.
Increase the setup cost in the formula to make this work. The result is
a reduced blanking mode increases by up to 7MHz while leaving the
standard timing
mode untouched

Issue is some displays go blank at the point of firmware to kms
handover. Plugging/unplugging hdmi cable, power cycling display, or
switching standby off/on
typically resolve this case.
Finally managed to find a display that suffers from this, and track down
the issue.
The firmware uses AVMUTE in normal operation. It will set AVMUTE before
disabling hdmi clocks and phy. It will clear AVMUTE after clocks and phy
are set up for a new hdmi mode.
But with the hdmi handover from firmware to kms, AVMUTE will be set by
firmware.
kms driver typically has no GCP packet (except for deep colour modes).
The spec isn't clear on whether to consider the AVMUTE as continuing
indefinitely in the absence of a GCP packet, or to consider that state
to have ended.
Most displays behave as we want, but there are a number (from multiple
manufacturers) which need to see AVMUTE cleared before displaying a
picture.
Lets just always enable GCP packet with AVMUTE cleared. That resolves
the issue on problematic displays.
From HDMI 1.4 spec:
A CD field of zero (Color Depth not indicated) shall be used whenever
the Sink does not indicate support for Deep Color. This value may
also be used in Deep Color mode to transmit a GCP indicating only
non-Deep Color information (e.g. AVMUTE).
So use CD=0 where we were previously not enabling a GCP.

YUV images can either be presented as one allocation with offsets
for the different planes, or multiple allocations with 0 offsets.
The driver only ever calls drm_fb_[dma|cma]_get_gem_obj with plane
index 0, therefore any application using the second approach was
incorrectly rendered.
Correctly determine the address for each plane, removing the
assumption that the base address is the same for each.

Currently amdgpu calls drm_sched_fini() from the fence driver sw fini
routine - such function is expected to be called only after the
respective init function - drm_sched_init() - was executed successfully.
Happens that we faced a driver probe failure in the Steam Deck
recently, and the function drm_sched_fini() was called even without
its counter-part had been previously called, causing the following oops:
amdgpu: probe of 0000:04:00.0 failed with error -110

To prevent that, check if the drm_sched was properly initialized for a
given ring before calling its fini counter-part.
Notice ideally we'd use sched.ready for that; such field is set as the latest
thing on drm_sched_init(). But amdgpu seems to "override" the meaning of such
field - in the above oops for example, it was a GFX ring causing the crash, and
the sched.ready field was set to true in the ring init routine, regardless of
the state of the DRM scheduler. Hence, we ended-up using sched.ops as per
Christian's suggestion [0], and also removed the no_scheduler check [1].

The pid field corresponds to the result of gettid() in userspace.
However, userspace cannot reliably attribute PTE events to processes
with just the thread id. This patch allows userspace to easily
attribute PTE update events to specific processes by comparing this
field with the result of getpid().
For attributing events to specific threads, the thread id is also
contained in the common fields of each trace event.

Cursor gets clipped off in the middle of the screen with hw rotation
180. Fix a miscalculation of cursor offset when it's placed near the
edges in the pipe split case.
Cursor bugs with hw rotation were reported on AMD issue tracker:
https://gitlab.freedesktop.org/drm/amd/-/issues/2247
The issues on rotation 270 was fixed by:
https://lore.kernel.org/amd-gfx/20221118125935.4013669-22-Brian.Chang@amd.com/
that partially addressed the rotation 180 too. So, this patch is the
final bits for rotation 180.

io_acct_set was enabled for raid0/raid5 io accounting. bios that contain
md_io_acct are allocated in the i/o path. There isn't a good method to
monitor if these bios are all finished and freed. In the takeover process,
io_acct_set (which is used for bios with md_io_acct) need to be freed.
However, if some bios finish after io_acct_set is freed, it may trigger
the following panic:

Arınç reports that on his MT7621AT Unielec U7621-06 board and MT7623NI
Bananapi BPI-R2, packets received by the CPU over mt7530 switch port 0
(of which this driver acts as the DSA master) are not processed
correctly by software. More precisely, they arrive without a DSA tag
(in packet or in the hwaccel area - skb_metadata_dst()), so DSA cannot
demux them towards the switch's interface for port 0. Traffic from other
ports receives a skb_metadata_dst() with the correct port and is demuxed
properly.
Looking at mtk_poll_rx(), it becomes apparent that this driver uses the
skb vlan hwaccel area:
union {
u32 vlan_all;
struct {
__be16 vlan_proto;
__u16 vlan_tci;
};
};
as a temporary storage for the VLAN hwaccel tag, or the DSA hwaccel tag.
If this is a DSA master it's a DSA hwaccel tag, and finally clears up
the skb VLAN hwaccel header.
I'm guessing that the problem is the (mis)use of API.
skb_vlan_tag_present() looks like this:
#define skb_vlan_tag_present(__skb) (!!(__skb)->vlan_all)
So if both vlan_proto and vlan_tci are zeroes, skb_vlan_tag_present()
returns precisely false. I don't know for sure what is the format of the
DSA hwaccel tag, but I surely know that lowermost 3 bits of vlan_proto
are 0 when receiving from port 0:
unsigned int port = vlan_proto & GENMASK(2, 0);
If the RX descriptor has no other bits set to non-zero values in
RX_DMA_VTAG, then the call to __vlan_hwaccel_put_tag() will not, in
fact, make the subsequent skb_vlan_tag_present() return true, because
it's implemented like this:
static inline void __vlan_hwaccel_put_tag(struct sk_buff *skb,
__be16 vlan_proto, u16 vlan_tci)
{
skb->vlan_proto = vlan_proto;
skb->vlan_tci = vlan_tci;
}
What we need to do to fix this problem (assuming this is the problem) is
to stop using skb->vlan_all as temporary storage for driver affairs, and
just create some local variables that serve the same purpose, but
hopefully better. Instead of calling skb_vlan_tag_present(), let's look
at a boolean has_hwaccel_tag which we set to true when the RX DMA
descriptors have something. Disambiguate based on netdev_uses_dsa()
whether this is a VLAN or DSA hwaccel tag, and only call
__vlan_hwaccel_put_tag() if we're certain it's a VLAN tag.
Arınç confirms that the treatment works, so this validates the
assumption.

The special tag is only enabled when the first MAC uses DSA. However, it
must be enabled when any MAC uses DSA. Change the check accordingly.
This fixes hardware DSA untagging not working on the second MAC of the
MT7621 and MT7623 SoCs, and likely other SoCs too. Therefore, remove the
check that disables hardware DSA untagging for the second MAC of the MT7621
and MT7623 SoCs.

On some platforms, 100/1000/2500 speeds seem to have sometimes problems
reporting false positive tx unit hang during stressful UDP traffic. Likely
other Intel drivers introduce responses to a tx hang. Update the 'tx hang'
comparator with the comparison of the head and tail of ring pointers and
restore the tx_timeout_factor to the previous value (one).
This can be test by using netperf or iperf3 applications.
Example:
iperf3 -s -p 5001
iperf3 -c 192.168.0.2 --udp -p 5001 --time 600 -b 0
netserver -p 16604

After calling irq_set_affinity_and_hint(), the cpumask pointer is
saved in desc->affinity_hint, and will be used later when reading
/proc/irq/<num>/affinity_hint. So the cpumask variable needs to be
persistent. Otherwise, we are accessing freed memory when reading
the affinity_hint file.
Also, need to clear affinity_hint before free_irq(), otherwise there
is a one-time warning and stack trace during module unloading:
