for physical objects, so it won't really matter allocation-wise.

Now this never really surfaced because sane 32bit kernels only have 1G

to adjust lowmem via a kconfig option. And the kernel seems to favour
high allocations on boot-up, hence the overlay blowing up reliably.

Because the patch is tiny and nicely shows how broken gen2 is it's imho
worth to merge despite the fact that mucking around with the lowmem/

Chris Wilson [Fri, 20 Aug 2010 08:13:36 +0000 (09:13 +0100)]
drm/kms: Add a module parameter to disable polling

Polling for a VGA device on an old system can be quite expensive,
causing latencies on the order of 600ms. As we hold the mode mutex for
this time and also need the same mutex to move the cursor, we trigger a
user-visible stall.

The real solution would involve improving the granulatity of the
locking and so perhaps performing some of the probing not under the lock
or some other updates can be done under different locks. Also reducing the
cost of probing for a non-existent monitor would be worthwhile. However,
exposing a parameter to disable polling is a simple workaround in the
meantime.

In order to accommodate users turning polling on and off at runtime, the
polling is potentially re-enabled on every probe. This is coupled to
the user calling xrandr, which seems to be a vaild time to reset the
polling timeout since the information on the connection has just been
updated. (The presumption being that all connections are probed in a
single xrandr pass, which is currently valid.)

usb: allow drivers to use allocated bandwidth until unbound

When using the remove sysfs file, the device configuration is set to -1
(unconfigured). This eventually unbind drivers with the bandwidth_mutex
held. Some drivers may call functions that hold said mutex, like
usb_reset_device. This is the case for rtl8187, for example. This will
lead to the same process holding the mutex twice, which deadlocks.

Besides, according to Alan Stern:
"The deadlock problem probably could be handled somehow, but there's a
separate issue: Until the usb_disable_device call finishes unbinding
the drivers, the drivers are free to continue using their allocated
bandwidth.  We musn't change the bandwidth allocations until after the
unbinding is done.  So this patch is indeed necessary."

Unbinding the driver before holding the bandwidth_mutex solves the
problem. If any operation after that fails, drivers are not bound again.
But that would be a problem anyway that the user may solve resetting the
device configuration to one that works, just like he would need to do in
most other failure cases.

tty: fix tty_line must not be equal to number of allocated tty pointers in tty driver

I found a bug "by chance" in drivers/char/tty_io.c

I mean "by chance" because I was just reading the code of the
tty_find_polling_driver() to make a new tty_find_by_name() function.

In tty_find_polling_driver() the driver actually test "tty_line <=
p->num" while num refers to the number of struct tty_struct pointers
allocated for the p->ttys (p is a tty_driver), and tty_line is scanned
in a tty name, which can be for example ttyS2. Then tty_line equals 2.
And if p->num is 2, we have only p->ttys[0] and p->ttys[1], but no
p->ttys[2].

This is actually unharmful, for tty_find_polling_driver() is used only
in drivers/serial/kgdboc.c, and there's a test over there to find a
console with a matching index, which will never happen.

This is still a bug anyway.

vt: Fix console corruption on driver hand-over.

After 02f0777a0d6560eb995aade34a1b82f95c0452da "vc_origin" is no
longer reset to the screen buffer before calling the con_init() hook
of the new console driver.

If the old driver wasn't using a fixed scanout buffer (e.g. the case
of vgacon) "vc_origin" may be a pointer to a VRAM location, and its
contents aren't guaranteed to be preserved after calling con_deinit()
on the old driver and con_init() on the new driver, i.e. the
subsequent console resize may fill the framebuffer with garbage.

It can be reproduced in the transition from vgacon to the nouveau
framebuffer driver: in that case the legacy VGA aperture "vc_origin"
points to becomes unreadable after fbcon_init().

This patch reverts the mentioned commit. To avoid the problem it
intended to fix, stop using "vc_scr_end" in vc_do_resize() to
calculate how many rows we have to copy (actually the code looks
simpler this way without the help of "vc_scr_end").

firewire: ohci: work around VIA and NEC PHY packet reception bug

VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.
