[PATCH] rocket.c: Fix ldisc ref count handling

2005-08-05T07:04:15+00:00

If bailing out because there is nothing to receive in rp_do_receive(),
tty_ldisc_deref is not called.  Failure to do so increases the ref count=20
and causes release_dev() to hang since it can't get the ref count to 0.

[PATCH] coverity: tty_ldisc_ref return null check

2005-07-15T21:15:26+00:00

We add a check of the return value of tty_ldisc_ref(), which
is checked 7 out of 8 times, e.g.:

149  		ld = tty_ldisc_ref(tty);
150  		if (ld != NULL) {
151  			if (ld->set_termios)
152  				(ld->set_termios)(tty, &old_termios);
153  			tty_ldisc_deref(ld);
154  		}

This defect was found automatically by Coverity Prevent, a static analysis
tool.

(akpm: presumably `ld' is never NULL.  Oh well)

[PATCH] tpm breaks 8139cp

2005-07-15T21:15:25+00:00

A problem was reported that the tpm driver was interfereing with
networking on the 8139 chipset.  The tpm driver was using a hard coded
the memory address instead of the value the BIOS was putting the chip
at.  This was in the tpm_lpc_bus_init function.  That function can be
replaced with querying the value at Vendor specific locations.  This
patch replaces all calls to tpm_lpc_bus_init and the hardcoding of the
base address with a lookup of the address at the correct vendor
location.

[PATCH] remove bogus hack from radeon IRQ handler

2005-06-10T09:27:51+00:00

This removes a bogus hack from the radeon IRQ handler.
There is a better fix from myself and benh in DRM CVS but I'll wait
until 2.6.13-rc so it gets more testing.

[PATCH] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).

2005-06-07T19:35:44+00:00

[AGPGART] Replace check_bridge_mode() with (bridge->mode & AGSTAT_MODE_3_0).

As mentioned earlier, the current check_bridge_mode() code assumes
that AGP bridges are PCI devices.  This isn't always true.  Definitely
not for HP zx1 chipset and the same seems to be the case for SGI's AGP
bridge.

The patch below fixes the problem by picking up the AGP_MODE_3_0 bit
from bridge->mode.  I feel like I may be missing something, since I
can't see any reason why check_bridge_mode() wasn't doing that in the
first place.  According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is
determined during the hardware reset and cannot be changed, so it
seems to me it should be safe to pick it up from bridge->mode.

With the patch applied, I can definitely use AGP acceleration both
with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an
ATI FireGL card).

Unless someone spots a problem, please apply this patch so 3d
acceleration can work on zx1 boxes again.

This makes AGP work again on machines with an AGP bridge that isn't a
PCI device.

[PATCH] AGP fix for Xen VMM

2005-06-07T19:35:43+00:00

When Linux is running on the Xen virtual machine monitor, physical
addresses are virtualised and cannot be directly referenced by the AGP
GART.  This patch fixes the GART driver for Xen by adding a layer of
abstraction between physical addresses and 'GART addresses'.

Architecture-specific functions are also defined for allocating and freeing
the GATT.  Xen requires this to ensure that table really is contiguous from
the point of view of the GART.

These extra interface functions are defined as 'no-ops' for all existing
architectures that use the GART driver.
