If the connector is eDP, it can only be DP, not TMDS. Always set the detected sink type. If the sink is detected as non-DP, but there is no EDID, you can still manually force the port on. If the sink type is DP and there's no DPCD, there's no way to force the monitor on since you need both ends to train the link. Signed-off-by:

The pins for ddc and aux are shared so you need to switch the mode when doing ddc. The ProcessAuxChannel table already sets the pin mode to DP. This should fix unreliable ddc issues on DP ports using non-DP monitors. Signed-off-by:

If we aren't changing the power state, no need to take locks and schedule fences, etc. There seem to be lock ordering issues in the CP and fence code in some cases; see bug 29140 below.

Always zero-init a structure on the stack which is returned by a function. Otherwise you may leak random stack data from previous function calls. This fixes the following warning I was seeing: CC [M] drivers/gpu/drm/radeon/radeon_atombios.o drivers/gpu/drm/radeon/radeon_atombios.c: In function "radeon_atom_get_hpd_info_from_gpio": drivers/gpu/drm/radeon/radeon_atombios.c:261: warning: "hpd.plugged_state" is used uninitialized in this function Signed-off-by:

With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory. This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation. Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau. v2: fix nouveau pushbuf arg (thanks to Ben for pointing it out) Reported-by:

non-critical issue, CVE-2010-2803 Userspace controls the amount of memory to be allocate, so it can get the ioctl to allocate more memory than the kernel uses, and get access to kernel stack. This can only be done for processes authenticated to the X server for DRI access, and if the user has DRI access. Fix is to just memset the data to 0 if the user doesn't copy into it in the first place. Reported-by:

When removing of the BKL the locking around lastclose() was rearranged and resulted in the holding of the open_count spinlock over the call into drm_lastclose(). The drivers were not ready for this path to be atomic - it may indeed involve long waits to release old objects and cleanup the GPU - and so we ended up scheduling whilst atomic.

This is consistent with trying to access a filename that not exist within a directory which is a good analogy here. The main reason for the change is that it is easy to confuse the error code of EBADF as an performing an ioctl on an invalid file descriptor (rather than an unknown object). Signed-off-by:

Smatch complained that the ERR_PTR from hwmon_device_register() wasn't handled. I added some error handling in radeon_hwmon_init() to silence the warning. Unfortunately errors from radeon_pm_init() aren't handled so this doesn't really make a difference beyond silencing the warning. Also I changed DRM_ERROR() to dev_err() which is the new preferred method. Signed-off-by:

Previously we added i2c buses as needed when enumerating connectors power management, etc. This only exposed the actual buses used and could have lead to the same buse getting created more than once if one buses was used for more than one purpose.

(For some reason I thought that went in ages ago ...) This fixes support for PCI domains in what should hopefully be a backward compatible way along with a change to libdrm. When the interface version is set to 1.4, we assume userspace understands domains and the world is at peace. We thus pass proper domain numbers instead of 0 to userspace. The newer libdrm will then try 1.4 first, and fallback to 1.1, along with ignoring domains in the later case (well, except on alpha of course) Signed-off-by:
