dwc3 core IRQ's depth (disable depth) is going out of sync due to
disabling it from dwc3's state machine when there are multiple
time USB composition switch is being performed before USB cable
connect. Linux IRQ framework doesn't decrement disable depth
count with enable_irq() when IRQ is enabled previously but it does
increment disable depth every time disable_irq() is called. This
results into dwc3 core IRQ to remain disable causing USB enumeration
failure as unknown device due to USB controller driver is not
seeing any of RESET and CONNECT DONE interrupt although USB controller
has posted those events into event buffer. Fix this issue by
making sure that USB core IRQ is disabled by default, and
enable/disable it from dwc3 suspend/resume only.

request_irq() for dwc irq is called in dwc3_gadget_start()
when msm-dwc3 is in suspended state because usb cable is not
connected. dwc3 resume happens upon USB connect, it enables
already enabled irq. This result into unbalanced enable irq
warning. Fix this by moving request_irq to dwc3_probe().

Add lineptr interrupt support by making use of INTR_PROG_LINE
register part of the interfaces. This would generate the interrupt
when the configured pixel location in the panel video timing in terms
of video raster structure is reached for the frame. The lineptr can
be updated through the lineptr_value node. Any modification to the value
would take effect immediately for video mode panels.
Write a value from 1 to [line size] to enable interrupts, 0 to disable:
/sys/devices/virtual/graphics/fb0/lineptr_value
To handle interrupt, read from:
/sys/devices/virtual/graphics/fb0/lineptr_event

The current GRO implementation relies on NET_RX to complete
processing or the max possible TCP segment size for it to flush the
GRO coalesced packets. This leads to coalescing a large number of
packets which translates to very few ACKs. Since the number of
ACKs are very few and delayed during the slow start phase (stretch
ACK's), we see that the initial throughput ramp up is slow compared
to normal RFC TCP where we send an ACK per two packets. Note that
there is no difference between GRO and non GRO after the max window
size is reached.
Add a mechanism within rmnet_data to force the flush of packets
every 10 micro seconds (experimentally determined) by default. This
is controlled by the module parameter "gro_flush_time" and can be
configured to any value less than a second. To disable this feature,
set this entry to 0.
This reduces the coalesce of packets which translates to increased
number of ACK's compared to normal GRO but lesser ACK's compared
to NO GRO. There is no increase in power for a day to day use case.
Note that this optimization is specific to TCP GRO path only.
Some useful stats below for TCP DL at 400Mbps -
|TCP GRO Default | TCP GRO flush timer 10us
==================================================================
iperf 1st second tput | 300Mbps | 330Mbps
coalesce ratio | 15 | 4.5
