Per confirmation with RLC firmware team, the RLC should
be unhalted after all RLC related firmwares uploaded.
However, in fact the RLC is unhalted immediately after
RLCG firmware uploaded. And that may causes unexpected
PSP hang on loading the succeeding RLC save restore
list related firmwares.
So, we correct the firmware loading sequence to load
RLC save restore list related firmwares before RLCG
ucode. That will help to get around this issue.

When smu version is larger than 0x41e2b, it will load
raven_kicker_rlc.bin.To enable gfxoff for raven_kicker_rlc.bin,it
needs to avoid adev->pm.pp_feature &= ~PP_GFXOFF_MASK when it loads

When the HDMI unbinds drm_connector_cleanup() and drm_encoder_cleanup()
are called. This also happens when the connector and the encoder are
destroyed. This double call triggers a NULL pointer exception.
The patch fixes this by removing the cleanup calls in the unbind
function.

There are some extra data transfer in dsi.
ex. LPX, hs_prepare, hs_zero, hs_exit and the sof/eof of dsi packet.
This signal will enlarge the line time. So the real frame on dsi bus
will be lower than calc by video timing.
So dsi driver reduces the hbp and hfp to keep the line time.

The original logic is ok for primary display, but will not find out
component for external display.
For example, plane->index is 6 for external display, but there are only
2 layer nr in external display, and this condition will never happen:
if (plane->index < (count + mtk_ddp_comp_layer_nr(comp)))
Fix this by using the offset of the plane to mtk_crtc->planes as index,
instead of plane->index.

In a case when a ptp chardev (like /dev/ptp0) is open but an underlying

easily in a kvm virtual machine:

int main() { ... fp = fopen("/dev/ptp0", "r"); ... sleep(10); }
ts# uname -r

ts# cat /proc/cmdline
... slub_debug=FZP
ts# modprobe ptp_kvm
ts# ./openptp0 &

opened /dev/ptp0, sleeping 10s...
ts# rmmod ptp_kvm
ts# ls /dev/ptp*
ls: cannot access '/dev/ptp*': No such file or directory

[ 48.045001] Fixing recursive fault but reboot is needed!
This happens in:
static void __fput(struct file *file)
{ ...
if (file->f_op->release)
file->f_op->release(inode, file); <<< cdev is kfree'd here
if (unlikely(S_ISCHR(inode->i_mode) && inode->i_cdev != NULL &&
!(mode & FMODE_PATH))) {
cdev_put(inode->i_cdev); <<< cdev fields are accessed here
Namely:
__fput()
posix_clock_release()
kref_put(&clk->kref, delete_clock) <<< the last reference
delete_clock()
delete_ptp_clock()
kfree(ptp) <<< cdev is embedded in ptp
cdev_put
module_put(p->owner) <<< *p is kfree'd, bang!
Here cdev is embedded in posix_clock which is embedded in ptp_clock.
The race happens because ptp_clock's lifetime is controlled by two
refcounts: kref and cdev.kobj in posix_clock. This is wrong.
Make ptp_clock's sysfs device a parent of cdev with cdev_device_add()
created especially for such cases. This way the parent device with its
ptp_clock is not released until all references to the cdev are released.
This adds a requirement that an initialized but not exposed struct
device should be provided to posix_clock_register() by a caller instead
of a simple dev_t.
This approach was adopted from the commit 72139dfa2464 ("watchdog: Fix
the race between the release of watchdog_core_data and cdev"). See
details of the implementation in the commit 233ed09d7fda ("chardev: add
helper function to register char devs with a struct device").

For first-generation switches (SJA1105E and SJA1105T):
- TPID means C-Tag (typically 0x8100)
- TPID2 means S-Tag (typically 0x88A8)
While for the second generation switches (SJA1105P, SJA1105Q, SJA1105R,
SJA1105S) it is the other way around:
- TPID means S-Tag (typically 0x88A8)
- TPID2 means C-Tag (typically 0x8100)
In other words, E/T tags untagged traffic with TPID, and P/Q/R/S with
TPID2.
So the patch mentioned below fixed VLAN filtering for P/Q/R/S, but broke
it for E/T.
We strive for a common code path for all switches in the family, so just
lie in the static config packing functions that TPID and TPID2 are at
swapped bit offsets than they actually are, for P/Q/R/S. This will make

The check originates from the initial implementation which was not based
on PTP time but on a standalone clock source. In the meantime we can now
program the PTPSCHTM register at runtime with the dynamic base time
(actually with a value that is 200 ns smaller, to avoid writing DELTA=0
in the Schedule Entry Points Parameters Table). And we also have logic
for moving the actual base time in the future of the PHC's current time
base, so the check for zero serves no purpose, since even if the user
will specify zero, that's not what will end up in the static config
table where the limitation is.

When activating tc-taprio offload on the switch ports, the TAS state
machine will try to check whether it is running or not, but will find
both the STARTED and STOPPED bits as false in the
sja1105_tas_check_running function. So the function will return -EINVAL
(an abnormal situation) and the kernel will keep printing this from the
TAS FSM workqueue:
[ 37.691971] sja1105 spi0.1: An operation returned -22
The reason is that the underlying function that gets called,
sja1105_ptp_commit, does not actually do a SPI_READ, but a SPI_WRITE. So
the command buffer remains initialized with zeroes instead of retrieving
the hardware state. Fix that.

The PTP egress timestamp N must be captured from register PTPEGR_TS[n],
where n = 2 * PORT + TSREG. There are 10 PTPEGR_TS registers, 2 per
port. We are only using TSREG=0.
As opposed to the management slots, which are 4 in number
(SJA1105_NUM_PORTS, minus the CPU port). Any management frame (which
includes PTP frames) can be sent to any non-CPU port through any
management slot. When the CPU port is not the last port (#4), there will
be a mismatch between the slot and the port number.
Luckily, the only mainline occurrence with this switch
(arch/arm/boot/dts/ls1021a-tsn.dts) does have the CPU port as #4, so the
issue did not manifest itself thus far.

Currently, VRRP packets and packets that hit exceptions during routing
(e.g., MTU error) are policed using the same policer towards the CPU.
This means, for example, that misconfiguration of the MTU on a routed
interface can prevent VRRP packets from reaching the CPU, which in turn
can cause the VRRP daemon to assume it is the Master router.
Fix this by using a dedicated policer for VRRP packets.

When a router interface (RIF) is created the MAC address of the backing
netdev is verified to have the same MSBs as existing RIFs. This is
required in order to avoid changing existing RIF MAC addresses that all
share the same MSBs.
Loopback RIFs are special in this regard as they do not have a MAC
address, given they are only used to loop packets from the overlay to
the underlay.
Without this change, an error is returned when trying to create a RIF
after the creation of a GRE tunnel that is represented by a loopback
RIF. 'rif->dev->dev_addr' points to the GRE device's local IP, which
does not share the same MSBs as physical interfaces. Adding an IP
address to any physical interface results in:
Error: mlxsw_spectrum: All router interface MAC addresses must have the
same prefix.
Fix this by skipping loopback RIFs during MAC validation.

GXBB and newer SoCs use the fixed FCLK_DIV2 (1GHz) clock as input for
the m250_sel clock. Meson8b and Meson8m2 use MPLL2 instead, whose rate
can be adjusted at runtime.
So far we have been running MPLL2 with ~250MHz (and the internal
m250_div with value 1), which worked enough that we could transfer data
with an TX delay of 4ns. Unfortunately there is high packet loss with
an RGMII PHY when transferring data (receiving data works fine though).
Odroid-C1's u-boot is running with a TX delay of only 2ns as well as
the internal m250_div set to 2 - no lost (TX) packets can be observed
with that setting in u-boot.
Manual testing has shown that the TX packet loss goes away when using
the following settings in Linux (the vendor kernel uses the same
settings):
- MPLL2 clock set to ~500MHz
- m250_div set to 2
- TX delay set to 2ns on the MAC side
Update the m250_div divider settings to only accept dividers greater or
equal 2 to fix the TX delay generated by the MAC.

I stumbled over an old OSA model that claims to support DIAG_ASSIST,
but then rejects the cmd to query its DIAG capabilities.
In the old code this was ok, as the returned raw error code was > 0.
Now that we translate the raw codes to errnos, the "rc < 0" causes us
to fail the initialization of the device.
The fix is trivial: don't bail out when the DIAG query fails. Such an
error is not critical, we can still use the device (with a slightly
reduced set of features).

Symptom: After vnicc/rx_bcast has been manually set to 0,
bridge_* sysfs parameters can still be set or written.
Only occurs on HiperSockets, as OSA doesn't support changing rx_bcast.
Vnic characteristics and bridgeport settings are mutually exclusive.
rx_bcast defaults to 1, so manually setting it to 0 should disable
bridge_* parameters.
Instead it makes sense here to check the supported mask. If the card
does not support vnicc at all, bridge commands are always allowed.

Symptom: Error message "Configuring the VNIC characteristics failed"
in dmesg whenever an OSA interface on z15 is set online.
The VNIC characteristics get re-programmed when setting a L2 device
online. This follows the selected 'wanted' characteristics - with the
exception that the INVISIBLE characteristic unconditionally gets
switched off.
For devices that don't support INVISIBLE (ie. OSA), the resulting
IO failure raises a noisy error message
("Configuring the VNIC characteristics failed").
For IQD, INVISIBLE is off by default anyways.
So don't unnecessarily special-case the INVISIBLE characteristic, and
thereby suppress the misleading error message on OSA devices.

qeth_l?_set_online() goes through a number of initialization steps, and
on any error uses qeth_l?_stop_card() to tear down the residual state.
The first initialization step is qeth_core_hardsetup_card(). When this
fails after having established a QDIO context on the device
(ie. somewhere after qeth_mpc_initialize()), qeth_l?_stop_card() doesn't
shut down this QDIO context again (since the card state hasn't
progressed from DOWN at this stage).
Even worse, we then call qdio_free() as final teardown step to free the
QDIO data structures - while some of them are still hooked into wider
QDIO infrastructure such as the IRQ list. This is inevitably followed by
use-after-frees and other nastyness.
Fix this by unconditionally calling qeth_qdio_clear_card() to shut down
the QDIO context, and also to halt/clear any pending activity on the
various IO channels.
Remove the naive attempt at handling the teardown in
qeth_mpc_initialize(), it clearly doesn't suffice and we're handling it
properly now in the wider teardown code.

The MTU update code is supposed to be invoked in response to real
networking events that update the PMTU. In IPv6 PMTU update function
__ip6_rt_update_pmtu() we called dst_confirm_neigh() to update neighbor
confirmed time.
But for tunnel code, it will call pmtu before xmit, like:
- tnl_update_pmtu()
- skb_dst_update_pmtu()
- ip6_rt_update_pmtu()
- __ip6_rt_update_pmtu()
- dst_confirm_neigh()
If the tunnel remote dst mac address changed and we still do the neigh
confirm, we will not be able to update neigh cache and ping6 remote
will failed.
So for this ip_tunnel_xmit() case, _EVEN_ if the MTU is changed, we
should not be invoking dst_confirm_neigh() as we have no evidence
of successful two-way communication at this point.
On the other hand it is also important to keep the neigh reachability fresh
for TCP flows, so we cannot remove this dst_confirm_neigh() call.
To fix the issue, we have to add a new bool parameter for dst_ops.update_pmtu
to choose whether we should do neigh update or not. I will add the parameter
in this patch and set all the callers to true to comply with the previous
way, and fix the tunnel code one by one on later patches.
v5: No change.
v4: No change.
v3: Do not remove dst_confirm_neigh, but add a new bool parameter in
dst_ops.update_pmtu to control whether we should do neighbor confirm.
Also split the big patch to small ones for each area.

overwriting the next fields in CFP_DATA(6) which would render the rule
inoperative.

The sector size of the block layer is 512 bytes, but integrity interval
size might be different (in case of 4K block size of the media). At the
initiator side the virtual start sector is the one that was originally
submitted by the block layer (512 bytes) for the Reftag usage. The
initiator converts the Reftag to integrity interval units and sends it to
the target. So the target virtual start sector should be calculated at
integrity interval units. prepare_fn() and complete_fn() don't remap
correctly the Reftag when using incorrect units of the virtual start
sector, which leads to the following protection error at the device:
"blk_update_request: protection error, dev sdb, sector 2048 op 0x0:(READ)
flags 0x10000 phys_seg 1 prio class 0"
To fix that, set the seed in integrity interval units.

If cxgb4i_ddp_init() fails then cdev->cdev2ppm will be NULL, so add a check
for NULL pointer before dereferencing it.

Since obj->frontbuffer is no longer protected by the struct_mutex, as we
are processing the execbuf, it may be removed. Mark the
intel_frontbuffer as rcu protected, and so acquire a reference to
the struct as we track activity upon it.
