CEA actually specifies an interlaced mode with even vtotal and supplies a diagram showing how this is supposed to work. Note that interlaced modes with an even vtotal seem to be a fairly recent invention. All modelines lore I could dig up with googling says that vtotal for interlaced modes _needs_ to be odd. But the even modelines in CEA are not a spec-bug, there's a figure in CEA-861-E called "Figure 5 Special Interlaced Video Format Timing (Even Vtotal)" that explains how it's supposed to work. Furthermore intel Bspec explicitly mentions that both odd and even interlaced vtotal are supported (VTOTAL register in the south display engine of PCH split chips). Acked-by:

The drm drivers set the fb_info->pixmap fields without setting fb_info->pixmap.addr. If this is not set the fb core will overwrite these all fb_info->pixmap fields anyway, so there is not much point in setting them in the first place. [airlied: dropped nvidiafb piece - not mine] Signed-off-by:

This allows to avoid talking to a non-responding bus repeatedly until we finally timeout after 15 attempts. We can do this by catching the -ENXIO error, provided by i2c_algo_bit:bit_doAddress call. Within the bit_doAddress we already try 3 times to get the edid data, so if the routine tells us that bus is not responding, it is mostly pointless to keep re-trying those attempts over and over again until we reach final number of retries. This change should fix https://bugs.freedesktop.org/show_bug.cgi?id=41059 and improve overall edid detection timing by 10-30% in most cases, and by a much larger margin in case of phantom outputs (up to 30x in one worst case). Timing results for i915-powered machines for 'time xrandr' command: Machine 1: from 0.840s to 0.290s Machine 2: from 0.315s to 0.280s Machine 3: from +/- 4s to 0.184s Timing results for HD5770 with 'time xrandr' command: Machine 4: from 3.210s to 1.060s Reviewed-by:

Starting with DCE3 hardware, atom contains a general purpose ProcessI2cChannelTransaction similar to ProcessAuxChannelTransaction. Add an implementation using the atom tables for DCE3+ hardware. This should be a little less CPU intensive than bit banging and may work better in certain cases. Enable it by setting the radeon hw_i2c module parameter to 1. E.g., radeon.hw_i2c=1 on the kernel command line in grub. Signed-off-by:

A udelay value of 20 leads to an I2C bus running at only 25 kbps. I2C devices can typically operate faster than this, 50 kbps should be fine for all devices (and compliant devices can always stretch the clock if needed.) FWIW, the vast majority of framebuffer drivers set udelay to 10 already. So set it to 10 in DRM drivers too, this will make EDID block reads faster. We might even lower the udelay value later if no problem is reported. Signed-off-by:

Its useful to be able to call the mode setting getter ioctls. Not requiring master fd, enables writing a simple program which can query the state of the video system. Since these ioctls are only "getters" there is no security or synchronization issues which would require master fd. Opening an new fd is already protected by the file permissions on the device file.

The rbd_client structure uses a kref to arrange for cleaning up and freeing an instance when its last reference is dropped. The cleanup routine is rbd_client_release(), and one of the things it does is delete the rbd_client from rbd_client_list. It acquires node_lock to do so, but the way it is done is still not safe. The problem is that when attempting to reuse an existing rbd_client, the structure found might already be in the process of getting destroyed and cleaned up. Here's the scenario, with "CLIENT" representing an existing rbd_client that's involved in the race: Thread on CPU A | Thread on CPU B --------------- | --------------- rbd_put_client(CLIENT) | rbd_get_client() kref_put() | (acquires node_lock) kref->refcount becomes 0 | __rbd_client_find() returns CLIENT calls rbd_client_release() | kref_get(&CLIENT->kref); | (releases node_lock) (acquires node_lock) | deletes CLIENT from list | ...and starts using CLIENT... (releases node_lock) | and frees CLIENT | <-- but CLIENT gets freed here Fix this by having rbd_put_client() acquire node_lock. The result could still be improved, but at least it avoids this problem. Signed-off-by:Alex Elder <elder@dreamhost.com> Signed-off-by:

This fixes the race in process_vm_core found by Oleg (see http://article.gmane.org/gmane.linux.kernel/1235667/ for details). This has been updated since I last sent it as the creation of the new mm_access() function did almost exactly the same thing as parts of the previous version of this patch did. In order to use mm_access() even when /proc isn't enabled, we move it to kernel/fork.c where other related process mm access functions already are. Signed-off-by:
