Subject: earlycon: Initialize port->uartclk based on clock-frequency property
From: Michal Simek <michal.simek@xilinx.com>
commit 814453adea7d081ad8917aa0f32d6a14165a3563 upstream.
On DT based platforms when current-speed property is present baudrate
is setup. Also port->uartclk is initialized to bogus BASE_BAUD * 16
value. Drivers like uartps/ns16550 contain logic when baudrate and
uartclk is used for baudrate calculation.
The patch is reading optional clock-frequency property to replace bogus
BASE_BAUD * 16 calculation to have proper baudrate calculation.
[-stable comment: commit 31cb9a8575ca ("earlycon: initialise baud field
of earlycon device structure") has changed 8250_early.c behavior which
now tries to setup UART speed. Ignoring clock-frequency results in
wrong value of calculated divisor & malformed early console output.]

Subject: earlycon: Remove hardcoded port->uartclk initialization in of_setup_earlycon
From: Michal Simek <michal.simek@xilinx.com>
commit 182ead3e418a20328b73152b8e81fc8b4cac3b0b upstream.
There is no reason to initialize uartclk to BASE_BAUD * 16 for DT based
systems.
[-stable comment: commit 31cb9a8575ca ("earlycon: initialise baud field

Already-backported upstream commit 0ff3ab701963 ("serial: 8250_early:
Only set divisor if valid clk & baud") handles properly uartclk not
being set but it still requires backporting fix for wrong uartclk val.
This fixes malformed early console output on arch-es with BASE_BAUD.]

It was reported that emulated e1000e devices in vmware esxi 6.5 Build
7526125 do not link up after commit 4aea7a5c5e94 ("e1000e: Avoid receiver
overrun interrupt bursts", v4.15-rc1). Some tracing shows that after
e1000e_trigger_lsc() is called, ICR reads out as 0x0 in e1000_msix_other()
on emulated e1000e devices. In comparison, on real e1000e 82574 hardware,
icr=0x80000004 (_INT_ASSERTED | _LSC) in the same situation.
Some experimentation showed that this flaw in vmware e1000e emulation can
be worked around by not setting Other in EIAC. This is how it was before
16ecba59bc33 ("e1000e: Do not read ICR in Other interrupt", v4.5-rc1).

This partially reverts commit 4aea7a5c5e940c1723add439f4088844cd26196d.
We keep the fix for the first part of the problem (1) described in the log
of that commit, that is to read ICR in the other interrupt handler. We
remove the fix for the second part of the problem (2), Other interrupt
throttling.
Bursts of "Other" interrupts may once again occur during rxo (receive
overflow) traffic conditions. This is deemed acceptable in the interest of
avoiding unforeseen fallout from changes that are not strictly necessary.
As discussed, the e1000e driver should be in "maintenance mode".

Restores the ICS write for Rx/Tx queue interrupts which was present before
commit 16ecba59bc33 ("e1000e: Do not read ICR in Other interrupt", v4.5-rc1)
but was not restored in commit 4aea7a5c5e94
("e1000e: Avoid receiver overrun interrupt bursts", v4.15-rc1).
This re-raises the queue interrupts in case the txq or rxq bits were set in
ICR and the Other interrupt handler read and cleared ICR before the queue
interrupt was raised.
Fixes: 4aea7a5c5e94 ("e1000e: Avoid receiver overrun interrupt bursts")

From: Benjamin Poirier <bpoirier@suse.com>
The 82574 specification update errata 12 states that interrupts may be
missed if ICR is read while INT_ASSERTED is not set. Avoid that problem by
setting all bits related to events that can trigger the Other interrupt in
IMS.
The Other interrupt is raised for such events regardless of whether or not
they are set in IMS. However, only when they are set is the INT_ASSERTED
bit also set in ICR.
By doing this, we ensure that INT_ASSERTED is always set when we read ICR
in e1000_msix_other() and steer clear of the errata. This also ensures that
ICR will automatically be cleared on read, therefore we no longer need to
clear bits explicitly.
