Sanity check the flags passed to change_mnt_propagation(). Exactly one flag should be set. Return EINVAL otherwise. Userspace can pass in arbitrary combinations of MS_* flags to mount(). do_change_type() is called if any of MS_SHARED, MS_PRIVATE, MS_SLAVE, or MS_UNBINDABLE is set. do_change_type() clears MS_REC and then calls change_mnt_propagation() with the rest of the user-supplied flags. change_mnt_propagation() clearly assumes only one flag is set but do_change_type() does not check that this is true. For example, mount() with flags MS_SHARED | MS_RDONLY does not actually make the mount shared or read-only but does clear MNT_UNBINDABLE. Signed-off-by:

Arguably this is a bug in drm-core in that we should not be called twice in succession with DPMS_ON, however this is still occuring and we see FDI link training failures on the second call leading to the occassional blank display.

We were passing garbage values into the panel-fitter control register when disabling it on Ironlake - those values (filter modes and reserved MBZ bits) would have then be re-used the next time panel-fitting was enabled. Signed-off-by: -

When we miss the flip prepare interrupt, we never get into the software state needed to restart userspace, resulting in a freeze of a full-screen OpenGL application (such as a compositor). Work around this by checking DSPxSURF/DSPxBASE to see if the page flip has actually happened. If it has, do the work we would have done when the flip prepare interrupt comes in. Also, add debugfs information to tell us what's going on (based on the patch from Chris Wilson attached to bugs.fdo bug #29798). Signed-off-by:

We reset intel_encoder for every matching encoder whilst iterating over the encoders attached to this crtc when changing mode. As such in a cloned configuration intel_encoder may not correspond to the correct is_edp encoder. By scoping intel_encoder to the loop, not only is the compiler able to spot this mistake, we also improve readiability for ourselves. [It might not be a mistake, within this function it is unclear as to whether it is permissable for eDP to be cloned...] Signed-off-by: -

If the VBIOS tells us the mapping of the SDVO device onto the DDC bus, use it. However, if there is no VBIOS available that mapping is uninitialised and we should fallback to our earlier guess. Fix regression introduced in b1083333 (which in turn is a fix for the regression caused by the introduction of this guess, 14571b4c).

i965 uses the Display Registers to compute the offset from the display base so the new base does not need adjusting when flipping. The older chipsets use a fence to access the display and so do perceive the surface as linear and have a single base register which is reprogrammed using the flip. Signed-off-by:

So set the coherent dma mask accordingly. This dma mask is only used for physical objects, so it won't really matter allocation-wise. Now this never really surfaced because sane 32bit kernels only have 1G of lowmem. But some eager testers (distros?) still carry around the patch 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/ highmem division is (no longer) supported.

Only fallback to a set of default modes on a connector iff that connector is known to be connected. The issue occurs that with limited hardware which cannot probe a connector and so reports the connector status as unknown will then attempt to retrieve the modes for it during drm_helper_probe_single_connector_modes(). Should that fail, the helper then generates a default set which fools the fb_helper and causes havoc with the console and beyond. Signed-off-by:

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.)

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. Signed-off-by:
