[GIT PULL] exynos-drm-next
by inki.dae＠samsung.com 02 Sep '15

02 Sep '15

Hi Dave, This is a last pull request, which includes two g2d patches I missed, and more cleanup series of Exynos drm driver. The cleanup series makes Exynos drm driver more simple, and removes unnecessary codes, and considers multiple plane format of framebuffer. I hope this not to be late. Please kindly let me know if there is any problem.

[PATCH 0/5] Documentation: drm: Make drm.tmpl build as pdfdoc
by Graham Whaley 02 Sep '15

02 Sep '15

A series of patches to make drm.tmpl build under 'make pdfdocs'. The biggest change is patch4 which converts a large HTML table into a CALS one. It should be noted, that table renders less than ideal in the PDF - something I have not figured out how to fix. Patch1 required some <sect> changes that then required some <title> additions. It would be good if they could be verified as suitable. This set applies against drm-intel-nightly 5606e1a after having my in-flight i915_guc_submission typo fix applied and Danilos 'Improve Markdown results' applied (which should not be needed to apply the patches, just to build the resulting pdf).

[PATCH 1/9] drm/exynos: remove exynos_drm_fb_set_buf_cnt()
by Joonyoung Shim 02 Sep '15

02 Sep '15

The exynos_drm_fb_set_buf_cnt() is used to set buffer count only in exynos_drm_fbdev_update(). This patch sets directly buffer count in exynos_drm_framebuffer_init() without using exynos_drm_fb_set_buf_cnt(), so there is no any reason to keep exynos_drm_fb_set_buf_cnt().

[PATCH] drm/dp: Adjust i2c-over-aux retry count based on message size and i2c bus speed
by ville.syrjala＠linux.intel.com 01 Sep '15

01 Sep '15

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Calculate the number of retries we should do for each i2c-over-aux message based on the time it takes to perform the i2c transfer vs. the aux transfer. This mostly matches what the DP spec recommends. The numbers didn't come out exactly the same as the tables in the spec, but I think there's something fishy about the AUX trasnfer size calculations in the spec. Also the way the i2c transfer length is calculated is somewhat open to interpretation. Note that currently we assume 10 kHz speed for the i2c bus. Some real world devices (eg. some Apple DP->VGA dongle) fails with less than 16 retries, and that would correspond to something close to 20 kHz, so we assume 10 kHz to be on the safe side. Ideally we should query/set the i2c bus speed via DPCD but for now this should at leaast remove the regression from the 1->16 byte trasnfer size change. And of course if the sink completes the transfer quicker this shouldn't slow things down since we don't change the interval between retries.
