Add support for the basic extended CAN controller (bxCAN) found in many
low- to middle-end STM32 SoCs. It supports the Basic Extended CAN
protocol versions 2.0A and B with a maximum bit rate of 1 Mbit/s.
The controller supports two channels (CAN1 as primary and CAN2 as
secondary) and the driver can enable either or both of the channels. They
share some of the required logic (e. g. clocks and filters), and that means
you cannot use the secondary CAN without enabling some hardware resources
managed by the primary CAN.
Each channel has 3 transmit mailboxes, 2 receive FIFOs with 3 stages and
28 scalable filter banks.
It also manages 4 dedicated interrupt vectors:
- transmit interrupt
- FIFO 0 receive interrupt
- FIFO 1 receive interrupt
- status change error interrupt
Driver uses all 3 available mailboxes for transmission and FIFO 0 for
reception. Rx filter rules are configured to the minimum. They accept
all messages and assign filter 0 to CAN1 and filter 14 to CAN2 in
identifier mask mode with 32 bits width. It enables and uses transmit,
receive buffers for FIFO 0 and error and status change interrupts.

The ENA driver allows for two distinct values for the number of bytes
of the packet's payload that can be written directly to the device.
For a value of 224 the driver turns on Large LLQ Header mode in which
the first 224 of the packet's payload are written to the LLQ.

Allow configuring the device with large LLQ headers. The Low Latency
Queue (LLQ) allows the driver to write the first N bytes of the packet,
along with the rest of the TX descriptors directly into device (N can be
either 96 or 224 for large LLQ headers configuration).
Having L4 TCP/UDP headers contained in the first 96 bytes of the packet
is required to get maximum performance from the device.

Currently, MAX_SKB_FRAGS value is 17.
For standard tcp sendmsg() traffic, no big deal because tcp_sendmsg()
attempts order-3 allocations, stuffing 32768 bytes per frag.
But with zero copy, we use order-0 pages.
For BIG TCP to show its full potential, we add a config option
to be able to fit up to 45 segments per skb.
This is also needed for BIG TCP rx zerocopy, as zerocopy currently
does not support skbs with frag list.
We have used MAX_SKB_FRAGS=45 value for years at Google before
we deployed 4K MTU, with no adverse effect, other than
a recent issue in mlx4, fixed in commit 26782aad00cc
("net/mlx4: MLX4_TX_BOUNCE_BUFFER_SIZE depends on MAX_SKB_FRAGS")
Back then, goal was to be able to receive full size (64KB) GRO
packets without the frag_list overhead.
Note that /proc/sys/net/core/max_skb_frags can also be used to limit
the number of fragments TCP can use in tx packets.
By default we keep the old/legacy value of 17 until we get
more coverage for the updated values.
Sizes of struct skb_shared_info on 64bit arches
MAX_SKB_FRAGS | sizeof(struct skb_shared_info):
==============================================
17 320
21 320+64 = 384
25 320+128 = 448
29 320+192 = 512
33 320+256 = 576
37 320+320 = 640
41 320+384 = 704
45 320+448 = 768
This inflation might cause problems for drivers assuming they could pack
both the incoming packet (for MTU=1500) and skb_shared_info in half a page,
using build_skb().
v3: fix build error when CONFIG_NET=n
v2: fix two build errors assuming MAX_SKB_FRAGS was "unsigned long"

LOOP_CONFIGURE is, as far as I understand it, supposed to be a way to
combine LOOP_SET_FD and LOOP_SET_STATUS64 into a single syscall. When
using LOOP_SET_FD+LOOP_SET_STATUS64, a single uevent would be sent for
each partition found on the loop device after the second ioctl(), but
when using LOOP_CONFIGURE, no such uevent was being sent.
In the old setup, uevents are disabled for LOOP_SET_FD, but not for
LOOP_SET_STATUS64. This makes sense, as it prevents uevents being
sent for a partially configured device during LOOP_SET_FD - they're
only sent at the end of LOOP_SET_STATUS64. But for LOOP_CONFIGURE,
uevents were disabled for the entire operation, so that final
notification was never issued. To fix this, reduce the critical
section to exclude the loop_reread_partitions() call, which causes
the uevents to be issued, to after uevents are re-enabled, matching
the behaviour of the LOOP_SET_FD+LOOP_SET_STATUS64 combination.
I noticed this because Busybox's losetup program recently changed from
using LOOP_SET_FD+LOOP_SET_STATUS64 to LOOP_CONFIGURE, and this broke
my setup, for which I want a notification from the kernel any time a
new partition becomes available.

For ACPI drivers that provide a ->notify() callback and set
ACPI_DRIVER_ALL_NOTIFY_EVENTS in their flags, that callback can be
invoked while either the ->add() or the ->remove() callback is running
without any synchronization at the bus type level which is counter to
the common-sense expectation that notification handling should only be
enabled when the driver is actually bound to the device. As a result,
if the driver is not careful enough, it's ->notify() callback may crash
when it is invoked too early or too late [1].
This issue has been amplified by commit d6fb6ee1820c ("ACPI: bus: Drop
driver member of struct acpi_device") that made acpi_bus_notify() check
for the presence of the driver and its ->notify() callback directly
instead of using an extra driver pointer that was only set and cleared
by the bus type code, but it was present before that commit although
it was harder to reproduce then.
It can be addressed by using the observation that
acpi_device_install_notify_handler() can be modified to install the
handler for all types of events when ACPI_DRIVER_ALL_NOTIFY_EVENTS is
set in the driver flags, in which case acpi_bus_notify() will not need
to invoke the driver's ->notify() callback any more and that callback
will only be invoked after acpi_device_install_notify_handler() has run
and before acpi_device_remove_notify_handler() runs, which implies the
correct ordering with respect to the other ACPI driver callbacks.
Modify the code accordingly and while at it, drop two redundant local
variables from acpi_bus_notify() and turn its description comment into
a proper kerneldoc one.

The device release callback function invoked to release the matrix device
uses the dev_get_drvdata(device *dev) function to retrieve the
pointer to the vfio_matrix_dev object in order to free its storage. The
problem is, this object is not stored as drvdata with the device; since the
kfree function will accept a NULL pointer, the memory for the
vfio_matrix_dev object is never freed.
Since the device being released is contained within the vfio_matrix_dev
object, the container_of macro will be used to retrieve its pointer.

For platforms with Alder Lake PCH (Alder Lake S and Raptor Lake S) the
slp_s0_residency attribute has been reporting the wrong value. Unlike other
platforms, ADL PCH does not have a counter for the time that the SLP_S0
signal was asserted. Instead, firmware uses the aggregate of the Low Power
Mode (LPM) substate counters as the S0ix value. Since the LPM counters run
at a different frequency, this lead to misreporting of the S0ix time.
Add a check for Alder Lake PCH and adjust the frequency accordingly when
display slp_s0_residency.

Currently i915_gem_object_is_framebuffer() doesn't treat the
BO containing the framebuffer's DPT as a framebuffer itself.
This means eg. that the shrinker can evict the DPT BO while
leaving the actual FB BO bound, when the DPT is allocated
from regular shmem.
That causes an immediate oops during hibernate as we
try to rewrite the PTEs inside the already evicted
DPT obj.
TODO: presumably this might also be the reason for the
DPT related display faults under heavy memory pressure,
but I'm still not sure how that would happen as the object
should be pinned by intel_dpt_pin() while in active use by
the display engine...

The commit renaming icl_tc_phy_is_in_safe_mode() to
icl_tc_phy_take_ownership() didn't flip the function's return value
accordingly, fix this up.
This didn't cause an actual problem besides state check errors, since
the function is only used during HW readout.

Keeping DC states enabled is incompatible with the _noarm()/_arm()
split we use for writing pipe/plane registers. When DC5 and PSR
are enabled, all pipe/plane registers effectively become self-arming
on account of DC5 exit arming the update, and PSR exit latching it.
What probably saves us most of the time is that (with PIPE_MISC[21]=0)
all pipe register writes themselves trigger PSR exit, and then
we don't re-enter PSR until the idle frame count has elapsed.
So it may be that the PSR exit happens already before we've
updated the state too much.
Also the PSR1 panel (at least on this KBL) seems to discard the first
frame we trasmit, presumably still scanning out from its internal
framebuffer at that point. So only the second frame we transmit is
actually visible. But I suppose that could also be panel specific
behaviour. I haven't checked out how other PSR panels behave, nor
did I bother to check what the eDP spec has to say about this.
And since this really is all about DC states, let's switch from
the MODESET domain to the DC_OFF domain. Functionally they are
100% identical. We should probably remove the MODESET domain...
And for good measure let's toss in an assert to the place where
we do the _noarm() register writes to make sure DC states are
in fact off.

Unlike SKL/GLK the ICL CSC unit suffers from a new issue where
CSC_MODE arming is sticky. That is, once armed it remains armed
causing the CSC coeff/offset registers to become effectively
self-arming.
CSC coeff/offset registers writes no longer disarm the CSC,
but fortunately register read still do. So we can use that
to disarm the CSC unit once the registers for the current
frame have been latched. This avoid s the self-arming behaviour
from persisting into the next frame's .color_commit_noarm()
call.

skl/glk
SKL/GLK CSC unit suffers from a nasty issue where a CSC
coeff/offset register read or write between DC5 exit and
PSR exit will undo the CSC arming performed by DMC, and
then during PSR exit the hardware will latch zeroes into
the active CSC registers. This causes any plane going
through the CSC to output all black.
We can sidestep the issue by making sure the PSR exit has
already actually happened before we touch the CSC coeff/offset
registers. Easiest way to guarantee that is to just move the
CSC programming back into the .color_commir_arm() as we force
a PSR exit (and crucially wait for it to actually happen)
prior to touching the arming registers.
When PSR (and thus also DC states) are disabled we don't
have anything to worry about, so we can keep using the
more optional _noarm() hook for writing the CSC registers.

We're going to want different behavior for skl/glk vs. icl
in .color_commit_noarm(), so split the hook into two. Arguably
we already had slightly different behaviour since
csc_enable/gamma_enable are never set on icl+, so the old
code was perhaps a bit confusing as well.

of functions across sysfs and PMU. Using common functions with sysfs in PMU
solves the issues of missing support for MTL and missing support for older

The blamed commit has introduced the following tests to
dwmac4_add_hw_vlan_rx_fltr(), called from stmmac_vlan_rx_add_vid():
if (hw->promisc) {
netdev_err(dev,
"Adding VLAN in promisc mode not supported\n");
return -EPERM;
}
"VLAN promiscuous" mode is keyed in this driver to IFF_PROMISC, and so,
vlan_vid_add() and vlan_vid_del() calls cannot take place in IFF_PROMISC
mode. I have the following 2 arguments that this restriction is.... hm,
how shall I put it nicely... unproductive :)
First, take the case of a Linux bridge. If the kernel is compiled with
CONFIG_BRIDGE_VLAN_FILTERING=y, then this bridge shall have a VLAN
database. The bridge shall try to call vlan_add_vid() on its bridge
ports for each VLAN in the VLAN table. It will do this irrespectively of
whether that port is *currently* VLAN-aware or not. So it will do this
even when the bridge was created with vlan_filtering 0.
But the Linux bridge, in VLAN-unaware mode, configures its ports in
promiscuous (IFF_PROMISC) mode, so that they accept packets with any
MAC DA (a switch must do this in order to forward those packets which
are not directly targeted to its MAC address).
As a result, the stmmac driver does not work as a bridge port, when the
kernel is compiled with CONFIG_BRIDGE_VLAN_FILTERING=y.
$ ip link add br0 type bridge && ip link set br0 up
$ ip link set eth0 master br0 && ip link set eth0 up
[ 2333.943296] br0: port 1(eth0) entered blocking state
[ 2333.943381] br0: port 1(eth0) entered disabled state
[ 2333.943782] device eth0 entered promiscuous mode
[ 2333.944080] 4033c000.ethernet eth0: Adding VLAN in promisc mode not supported
[ 2333.976509] 4033c000.ethernet eth0: failed to initialize vlan filtering on this port
RTNETLINK answers: Operation not permitted
Secondly, take the case of stmmac as DSA master. Some switch tagging
protocols are based on 802.1Q VLANs (tag_sja1105.c), and as such,
tag_8021q.c uses vlan_vid_add() to work with VLAN-filtering DSA masters.
But also, when a DSA port becomes promiscuous (for example when it joins
a bridge), the DSA framework also makes the DSA master promiscuous.
Moreover, for every VLAN that a DSA switch sends to the CPU, DSA also
programs a VLAN filter on the DSA master, because if the the DSA switch
uses a tail tag, then the hardware frame parser of the DSA master will
see VLAN as VLAN, and might filter them out, for being unknown.
Due to the above 2 reasons, my belief is that the stmmac driver does not
get to choose to not accept vlan_vid_add() calls while IFF_PROMISC is
enabled, because the 2 are completely independent and there are code
paths in the network stack which directly lead to this situation
occurring, without the user's direct input.
In fact, my belief is that "VLAN promiscuous" mode should have never
been keyed on IFF_PROMISC in the first place, but rather, on the
NETIF_F_HW_VLAN_CTAG_FILTER feature flag which can be toggled by the
user through ethtool -k, when present in netdev->hw_features.
In the stmmac driver, NETIF_F_HW_VLAN_CTAG_FILTER is only present in
"features", making this feature "on [fixed]".
I have this belief because I am unaware of any definition of promiscuity
which implies having an effect on anything other than MAC DA (therefore
not VLAN). However, I seem to be rather alone in having this opinion,
looking back at the disagreements from this discussion:
https://lore.kernel.org/netdev/20201110153958.ci5ekor3o2ekg3ky@ipetronik.com/
In any case, to remove the vlan_vid_add() dependency on !IFF_PROMISC,
one would need to remove the check and see what fails. I guess the test
was there because of the way in which dwmac4_vlan_promisc_enable() is
implemented.
For context, the dwmac4 supports Perfect Filtering for a limited number
of VLANs - dwmac4_get_num_vlan(), priv->hw->num_vlan, with a fallback on
Hash Filtering - priv->dma_cap.vlhash - see stmmac_vlan_update(), also
visible in cat /sys/kernel/debug/stmmaceth/eth0/dma_cap | grep 'VLAN
Hash Filtering'.
The perfect filtering is based on MAC_VLAN_Tag_Filter/MAC_VLAN_Tag_Data
registers, accessed in the driver through dwmac4_write_vlan_filter().
The hash filtering is based on the MAC_VLAN_Hash_Table register, named
GMAC_VLAN_HASH_TABLE in the driver and accessed by dwmac4_update_vlan_hash().
The control bit for enabling hash filtering is GMAC_VLAN_VTHM
(MAC_VLAN_Tag_Ctrl bit VTHM: VLAN Tag Hash Table Match Enable).
Now, the description of dwmac4_vlan_promisc_enable() is that it iterates
through the driver's cache of perfect filter entries (hw->vlan_filter[i],
added by dwmac4_add_hw_vlan_rx_fltr()), and evicts them from hardware by
unsetting their GMAC_VLAN_TAG_DATA_VEN (MAC_VLAN_Tag_Data bit VEN - VLAN
Tag Enable) bit. Then it unsets the GMAC_VLAN_VTHM bit, which disables
hash matching.
This leaves the MAC, according to table "VLAN Match Status" from the
documentation, to always enter these data paths:
VID |VLAN Perfect Filter |VTHM Bit |VLAN Hash Filter |Final VLAN Match
|Match Result | |Match Result |Status
-------|--------------------|---------|-----------------|----------------
VID!=0 |Fail |0 |don't care |Pass
So, dwmac4_vlan_promisc_enable() does its job, but by unsetting
GMAC_VLAN_VTHM, it conflicts with the other code path which controls
this bit: dwmac4_update_vlan_hash(), called through stmmac_update_vlan_hash()
from stmmac_vlan_rx_add_vid() and from stmmac_vlan_rx_kill_vid().
This is, I guess, why dwmac4_add_hw_vlan_rx_fltr() is not allowed to run
after dwmac4_vlan_promisc_enable() has unset GMAC_VLAN_VTHM: because if
it did, then dwmac4_update_vlan_hash() would set GMAC_VLAN_VTHM again,
breaking the "VLAN promiscuity".
It turns out that dwmac4_vlan_promisc_enable() is way too complicated
for what needs to be done. The MAC_Packet_Filter register also has the
VTFE bit (VLAN Tag Filter Enable), which simply controls whether VLAN
tagged packets which don't match the filtering tables (either perfect or
hash) are dropped or not. At the moment, this driver unconditionally
sets GMAC_PACKET_FILTER_VTFE if NETIF_F_HW_VLAN_CTAG_FILTER was detected
through the priv->dma_cap.vlhash capability bits of the device, in
stmmac_dvr_probe().
I would suggest deleting the unnecessarily complex logic from
dwmac4_vlan_promisc_enable(), and simply unsetting GMAC_PACKET_FILTER_VTFE
when becoming IFF_PROMISC, which has the same effect of allowing packets
with any VLAN tags, but has the additional benefit of being able to run
concurrently with stmmac_vlan_rx_add_vid() and stmmac_vlan_rx_kill_vid().
As much as I believe that the VTFE bit should have been exclusively
controlled by NETIF_F_HW_VLAN_CTAG_FILTER through ethtool, and not by
IFF_PROMISC, changing that is not a punctual fix to the problem, and it
would probably break the VFFQ feature added by the later commit
e0f9956a3862 ("net: stmmac: Add option for VLAN filter fail queue
enable"). From the commit description, VFFQ needs IFF_PROMISC=on and
VTFE=off in order to work (and this change respects that). But if VTFE
was changed to be controlled through ethtool -k, then a user-visible
change would have been introduced in Intel's scripts (a need to run
"ethtool -k eth0 rx-vlan-filter off" which did not exist before).
The patch was tested with this set of commands:
ip link set eth0 up
ip link add link eth0 name eth0.100 type vlan id 100
ip addr add 192.168.100.2/24 dev eth0.100 && ip link set eth0.100 up

# Wait for VLAN-tagged pings from the other end...
# Check with "tcpdump -i eth0 -e -n -p" and we shouldn't see them

Instead of registering one interrupt handler for all four SBUS Quattro
HMEs, let each HME register its own handler. To make this work, we don't
handle the IRQ if none of the status bits are set. This reduces the
complexity of the driver, and makes it easier to ensure things happen
before/after enabling IRQs.
I'm not really sure why we request IRQs in two different places (and leave
them running after removing the driver!). A lot of things in this driver
seem to just be crusty, and not necessarily intentional. I'm assuming
that's the case here as well.
This really needs to be tested by someone with an SBUS Quattro card.
