Core Changes: Fixed regressions introduced by commit cd82d82cbc04
("drm/dp_mst: Add branch bandwidth validation to MST atomic check"),
which would cause us to:
* Calculate the available bandwidth on an MST topology incorrectly, and
as a result reject most display configurations that would try to enable
more then one sink on a topology
* Occasionally expose MST connectors to userspace before finishing
probing their PBN capabilities, resulting in us rejecting display
configurations because we assumed briefly that no bandwidth was
available

Sigh, this is mostly my fault for not giving commit cd82d82cbc04
("drm/dp_mst: Add branch bandwidth validation to MST atomic check")
enough scrutiny during review. The way we're checking bandwidth
limitations here is mostly wrong:
For starters, drm_dp_mst_atomic_check_bw_limit() determines the
pbn_limit of a branch by simply scanning each port on the current branch
device, then uses the last non-zero full_pbn value that it finds. It
then counts the sum of the PBN used on each branch device for that
level, and compares against the full_pbn value it found before.
This is wrong because ports can and will have different PBN limitations
on many hubs, especially since a number of DisplayPort hubs out there
will be clever and only use the smallest link rate required for each
downstream sink - potentially giving every port a different full_pbn
value depending on what link rate it's trained at. This means with our
current code, which max PBN value we end up with is not well defined.
Additionally, we also need to remember when checking bandwidth
limitations that the top-most device in any MST topology is a branch
device, not a port. This means that the first level of a topology
doesn't technically have a full_pbn value that needs to be checked.
Instead, we should assume that so long as our VCPI allocations fit we're
within the bandwidth limitations of the primary MSTB.
We do however, want to check full_pbn on every port including those of
the primary MSTB. However, it's important to keep in mind that this
value represents the minimum link rate /between a port's sink or mstb,
and the mstb itself/. A quick diagram to explain:
MSTB #1
/ \
/ \
Port #1 Port #2
full_pbn for Port #1 → | | ← full_pbn for Port #2
Sink #1 MSTB #2
|
etc...
Note that in the above diagram, the combined PBN from all VCPI
allocations on said hub should not exceed the full_pbn value of port #2,
and the display configuration on sink #1 should not exceed the full_pbn
value of port #1. However, port #1 and port #2 can otherwise consume as
much bandwidth as they want so long as their VCPI allocations still fit.
And finally - our current bandwidth checking code also makes the mistake
of not checking whether something is an end device or not before trying
to traverse down it.
So, let's fix it by rewriting our bandwidth checking helpers. We split
the function into one part for handling branches which simply adds up
the total PBN on each branch and returns it, and one for checking each
port to ensure we're not going over its PBN limit. Phew.
This should fix regressions seen, where we erroneously reject display
configurations due to thinking they're going over our bandwidth limits
when they're not.
Changes since v1:
* Took an even closer look at how PBN limitations are supposed to be
handled, and did some experimenting with Sean Paul. Ended up rewriting
these helpers again, but this time they should actually be correct!
Changes since v2:
* Small indenting fix
* Fix pbn_used check in drm_dp_mst_atomic_check_port_bw_limit()

We used to punt off reprobing path resources to the link address probe
work, but now that we handle CSNs asynchronously from the driver's HPD
handling we can do whatever the heck we want from the CSN!
So, reprobe the path resources from drm_dp_mst_handle_conn_stat(). Also,
get rid of the path resource reprobing code in
drm_dp_check_and_send_link_address() since it's needlessly complicated
when we already reprobe path resources from
drm_dp_handle_link_address_port(). And finally, teach
drm_dp_send_enum_path_resources() to return 1 on PBN changes so we know
if we need to send another hotplug or not.
This fixes issues where we've indicated to userspace that a port has
just been connected, before we actually probed it's available PBN -
something that results in unexpected atomic check failures.

DisplayPort specifications are fun. For a while, it's been really
unclear to us what available_pbn actually does. There's a somewhat vague
explanation in the DisplayPort spec (starting from 1.2) that partially
explains it:
The minimum payload bandwidth number supported by the path. Each node
updates this number with its available payload bandwidth number if its
payload bandwidth number is less than that in the Message Transaction
reply.
So, it sounds like available_pbn represents the smallest link rate in
use between the source and the branch device. Cool, so full_pbn is just
the highest possible PBN that the branch device supports right?
Well, we assumed that for quite a while until Sean Paul noticed that on
some MST hubs, available_pbn will actually get set to 0 whenever there's
any active payloads on the respective branch device. This caused quite a
bit of confusion since clearing the payload ID table would end up fixing
the available_pbn value.
So, we just went with that until commit cd82d82cbc04 ("drm/dp_mst: Add
branch bandwidth validation to MST atomic check") started breaking
people's setups due to us getting erroneous available_pbn values. So, we
did some more digging and got confused until we finally looked at the
definition for full_pbn:
The bandwidth of the link at the trained link rate and lane count
between the DP Source device and the DP Sink device with no time slots
allocated to VC Payloads, represented as a Payload Bandwidth Number. As
with the Available_Payload_Bandwidth_Number, this number is determined
by the link with the lowest lane count and link rate.
That's what we get for not reading specs closely enough, hehe. So, since
full_pbn is definitely what we want for doing bandwidth restriction
checks - let's start using that instead and ignore available_pbn
entirely.

So far we have the unfortunate situation that mdio_bus_phy_may_suspend()
is called in suspend AND resume path, assuming that function result is
the same. After the original change this is no longer the case,
resulting in broken resume as reported by Geert.
To fix this call mdio_bus_phy_may_suspend() in the suspend path only,
and let the phy_device store the info whether it was suspended by
MDIO bus PM.

The eswitch offloads table, which has the reps (vport) rx miss rules,
was moved from OFFLOADS namespace [0,0] (prio, level), to [1,0], so
the restore table (the new [0,0]) can come before it. The destinations
of these miss rules is the rep root ft (ttc for non uplink reps).
Uplink rep root ft is created as OFFLOADS namespace [0,1], and is used
as a hook to next RX prio (either ethtool or ttc), but this fails to
pass fs_core level's check.
Move uplink rep root ft to OFFLOADS prio 1, level 1 ([1,1]), so it
will keep the same relative position after the restore table
change.

Converting fallthrough comments to fallthrough; creates warnings
in this code when compiled with gcc.
This code is overly complicated and reads rather better with a
little refactoring and no fallthrough uses at all.
Remove the fallthrough comments and simplify the written source
code while reducing the object code size.
Consolidate duplicated switch/case blocks for IPV4 and IPV6.

Pull IPMI fix from Corey Minyard:
"Fix a message spew on some system
The call to platform_get_irq() was changed to print a log if the
interrupt was not available, and that was causing bogus messages to
spew out for the IPMI driver. People have requested that this get in
to 5.6 so I'm sending it along"
* tag 'for-linus-5.6-2' of git://github.com/cminyard/linux-ipmi:
ipmi_si: Avoid spurious errors for optional IRQs
|
|
Per the dt-binding the interrupt is optional so use
platform_get_irq_optional() instead of platform_get_irq(). Since
commit 7723f4c5ecdb ("driver core: platform: Add an error message to
platform_get_irq*()") platform_get_irq() produces an error message
orion-mdio f1072004.mdio: IRQ index 0 not found
which is perfectly normal if one hasn't specified the optional property
in the device tree.

Only the bottom 12 bits contain the ATU bin occupancy statistics. The

The RX buffer pool is allocated in qeth_alloc_qdio_queues().
A subsequent pool resizing is then handled in a very simple way:
first free the current pool, then allocate a new pool of the requested
size.
There's two ways where this can go wrong:
1. if the resize action happens _before_ the initial pool was allocated,
then a subsequent initialization will call qeth_alloc_qdio_queues()
and fill the pool with a second(!) set of pages. We consume twice the
planned amount of memory.
This is easy to fix - just skip the resizing if the queues haven't
been allocated yet.
2. if the initial pool was created by qeth_alloc_qdio_queues() but a
subsequent resizing fails, then the device has no(!) RX buffer pool.
The next initialization will _not_ call qeth_alloc_qdio_queues(), and
attempting to back the RX buffers with pages in
qeth_init_qdio_queues() will fail.
Not very difficult to fix either - instead of re-allocating the whole
pool, just allocate/free as many entries to match the desired size.
