2012-02-13drm/modes: do not enforce an odd vtotal for interlaced modesDaniel Vetter
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).

2012-02-03drm: give up on edid retries when i2c bus is not respondingEugeni Dodonov
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: Chris Wilson <chris@hchris-wilson.co.uk> Reviewed-by: Keith Packard <keithp@keithp.com> Tested-by: Sean Finney <seanius@seanius.net> Tested-by: Soren Hansen <soren@linux2go.dk> Tested-by: Hernando Torque <sirius@sonnenkinder.org> Tested-by: Mike Lothian <mike@fireburn.co.uk> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=41059 Signed-off-by: Eugeni Dodonov <eugeni.dodonov@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2012-02-03drm/kms: Make i2c buses fasterJean Delvare
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.

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.

2012-02-02rbd: fix safety of rbd_put_client()Alex Elder
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: Sage Weil <sage@newdream.net>

2012-02-02drm/radeon/kms/blit: fix blit copy for very large buffersIlija Hadzic
Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason why someone would modify that algorithm is to tune the performance of buffer moves). The root cause was in i2f() function which only operated on range between 0 and 16383. Fix this by extending the range of i2f() function to 0 to 32767. While at it improve the function so that the range can be easily extended in the future (if it becomes necessary), cleanup lines over 80 characters, and replace in-line comments with one strategic comment that explains the crux of the function. Credits to michel@daenzer.net for pointing out the root cause of the bug. v2: Fix I2F_MAX_INPUT constant definition goof and warn only once if input argument is out of range.

2012-02-01drm/radeon: Set DESKTOP_HEIGHT register to the framebuffer (not mode) height.Michel Dänzer
The value of this register is transferred to the V_COUNTER register at the beginning of vertical blank. V_COUNTER is the reference for VLINE waits and goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout, so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the beginning of vertical blank, and VLINE waits excluding the whole scanout area could never finish (possibly only if VIEWPORT_Y_START is larger than the length of vertical blank in scanlines).
