UEFI/RM no longer use IED scripts from the VBIOS, though they appear to

Unfortunately, we require some hacks to do so, as the BeforeLinkTraining
IED script became a pointer to an array of scripts instead, without a
revbump of the relevant tables.

There's also some changes to SOR clock divider fiddling, which are

to improve review rate. We have a check in patchwork which validates

to force people to CC maintainers who we haven't seen on the mailing
list for years. This series removes from maintainers folks who didn't
provide any tag (incl. authoring a patch) in the last 5 years.
To ensure reasonable signal to noise ratio we only considered
MAINTAINERS entries which had more than 100 patches fall under
them in that time period.

All this is purely a process-greasing exercise, I hope nobody
sees this series as an affront. Most folks are moved to CREDITS,
a couple entries are simply removed.

The following inactive maintainers are kept, because they indicated

 - Christian Benvenuti (Cisco drivers)
 - Felix Fietkau (mtk-eth)

3 years agonet: avoid 32 x truesize under-estimation for tiny skbs
Eric Dumazet [Wed, 13 Jan 2021 16:18:19 +0000 (08:18 -0800)]
net: avoid 32 x truesize under-estimation for tiny skbs

Both virtio net and napi_get_frags() allocate skbs
with a very small skb->head

While using page fragments instead of a kmalloc backed skb->head might give
a small performance improvement in some cases, there is a huge risk of
under estimating memory usage.

For both GOOD_COPY_LEN and GRO_MAX_HEAD, we can fit at least 32 allocations
per page (order-3 page in x86), or even 64 on PowerPC

We have been tracking OOM issues on GKE hosts hitting tcp_mem limits
but consuming far more memory for TCP buffers than instructed in tcp_mem[2]

Even if we force napi_alloc_skb() to only use order-0 pages, the issue
would still be there on arches with PAGE_SIZE >= 32768

This patch makes sure that small skb head are kmalloc backed, so that
other objects in the slab page can be reused instead of being held as long
as skbs are sitting in socket queues.

Note that we might in the future use the sk_buff napi cache,
instead of going through a more expensive __alloc_skb()

Another idea would be to use separate page sizes depending
on the allocated length (to never have more than 4 frags per page)

I would like to thank Greg Thelen for his precious help on this matter,
analysing crash dumps is always a time consuming task.

3 years agonet: stmmac: fix taprio configuration when base_time is in the past
Yannick Vignon [Wed, 13 Jan 2021 13:15:57 +0000 (14:15 +0100)]
net: stmmac: fix taprio configuration when base_time is in the past

The Synopsys TSN MAC supports Qbv base times in the past, but only up to a
certain limit. As a result, a taprio qdisc configuration with a small
base time (for example when treating the base time as a simple phase
offset) is not applied by the hardware and silently ignored.

This was observed on an NXP i.MX8MPlus device, but likely affects all
TSN-variants of the MAC.

Fix the issue by making sure the base time is in the future, pushing it by
an integer amount of cycle times if needed. (a similar check is already
done in several other taprio implementations, see for example
drivers/net/ethernet/intel/igc/igc_tsn.c#L116 or
drivers/net/dsa/sja1105/sja1105_ptp.h#L39).

Yannick Vignon [Wed, 13 Jan 2021 13:15:56 +0000 (14:15 +0100)]
net: stmmac: fix taprio schedule configuration

When configuring a 802.1Qbv schedule through the tc taprio qdisc on an NXP
i.MX8MPlus device, the effective cycle time differed from the requested one
by N*96ns, with N number of entries in the Qbv Gate Control List. This is
because the driver was adding a 96ns margin to each interval of the GCL,
apparently to account for the IPG. The problem was observed on NXP
i.MX8MPlus devices but likely affected all devices relying on the same
configuration callback (dwmac 4.00, 4.10, 5.10 variants).

Fix the issue by removing the margins, and simply setup the MAC with the
provided cycle time value. This is the behavior expected by the user-space
API, as altering the Qbv schedule timings would break standards conformance.
This is also the behavior of several other Ethernet MAC implementations
supporting taprio, including the dwxgmac variant of stmmac.

This occurs when, for example, when on an x86_64 with a single NUMA node
because kfd_fill_iolink_info_for_cpu() is a no-op, but afterwards the
sub_type_hdr->length, which is out-of-bounds, is read and multiplied by
entries. Fortunately, entries is 0 in this case so the overall
crat_table->length is still correct.

Revert "drm/amd/display: Fixed Intermittent blue screen on OLED panel"

commit a861736dae64 ("drm/amd/display: Fixed Intermittent blue screen on OLED panel")

causes power regression for many users. It seems that this change causes
the MCLK to get forced high; this creates a regression for many users
since their devices were not able to drop to a low state after this
change. For this reason, this reverts commit
a861736dae644a0d7abbca0c638ae6aad28feeb8.

drm/amd/display: disable dcn10 pipe split by default

[Why]
The initial purpose of dcn10 pipe split is to support some high
bandwidth mode which requires dispclk greater than max dispclk. By
initial bring up power measurement data, it showed power consumption is
less with pipe split for dcn block. This could be reason for enable pipe
split by default. By battery life measurement of some Chromebooks,
result shows battery life is longer with pipe split disabled.

[How]
Disable pipe split by default. Pipe split could be still enabled when
required dispclk is greater than max dispclk.

x86/xen: Fix xen_hvm_smp_init() when vector callback not available

Only the IPI-related functions in the smp_ops should be conditional
on the vector callback being available. The rest should still happen:

 • xen_hvm_smp_prepare_boot_cpu()

   This function does two things, both of which should still happen if
   there is no vector callback support.

   The call to xen_vcpu_setup() for vCPU0 should still happen as it just
   sets up the vcpu_info for CPU0. That does happen for the secondary
   vCPUs too, from xen_cpu_up_prepare_hvm().

   The second thing it does is call xen_init_spinlocks(), which perhaps
   counter-intuitively should *also* still be happening in the case
   without vector callbacks, so that it can clear its local xen_pvspin
   flag and disable the virt_spin_lock_key accordingly.

   Checking xen_have_vector_callback in xen_init_spinlocks() itself
   would affect PV guests, so set the global nopvspin flag in
   xen_hvm_smp_init() instead, when vector callbacks aren't available.

 • xen_hvm_smp_prepare_cpus()

   This does some IPI-related setup by calling xen_smp_intr_init() and
   xen_init_lock_cpu(), which can be made conditional. And it sets the
   xen_vcpu_id to XEN_VCPU_ID_INVALID for all possible CPUS, which does
   need to happen.

 • xen_smp_cpus_done()

   This offlines any vCPUs which doesn't fit in the global shared_info
   page, if separate vcpu_info placement isn't available. That part also
   needs to happen regardless of vector callback support.

 • xen_hvm_cpu_die()

   This doesn't actually do anything other than commin_cpu_die() right
   right now in the !vector_callback case; all three teardown functions
   it calls should be no-ops. But to guard against future regressions
   it's useful to call it anyway, and for it to explicitly check for
   xen_have_vector_callback before calling those additional functions.

3 years agoxen: Fix event channel callback via INTX/GSI
David Woodhouse [Wed, 13 Jan 2021 13:26:02 +0000 (13:26 +0000)]
xen: Fix event channel callback via INTX/GSI

For a while, event channel notification via the PCI platform device
has been broken, because we attempt to communicate with xenstore before
we even have notifications working, with the xs_reset_watches() call
in xs_init().

We tend to get away with this on Xen versions below 4.0 because we avoid
calling xs_reset_watches() anyway, because xenstore might not cope with
reading a non-existent key. And newer Xen *does* have the vector
callback support, so we rarely fall back to INTX/GSI delivery.

To fix it, clean up a bit of the mess of xs_init() and xenbus_probe()
startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM
case, deferring it to be called from xenbus_probe() in the XS_HVM case
instead.

Then fix up the invocation of xenbus_probe() to happen either from its
device_initcall if the callback is available early enough, or when the
callback is finally set up. This means that the hack of calling
xenbus_probe() from a workqueue after the first interrupt, or directly
from the PCI platform device setup, is no longer needed.
