[PATCH v2] drm/radeon/kms: Run DDC buses at 50 kbps
by Jean Delvare 21 Mar '12

21 Mar '12

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.

[PATCH 2/2] drm/radeon/kms: Use the standard VESA timeout for DDC channels
by Jean Delvare 21 Mar '12

21 Mar '12

The VESA specification suggests a 2.2 ms timeout on DDC channels. Use exactly that (as the i915 driver does) instead of hard-coding a jiffy count.

[PATCH v2 00/14] updated exynos-drm-next.
by Inki Dae 21 Mar '12

21 Mar '12

Hi, Dave and all. this update adds new features below: - add HDMI version 1.4 and Audio support. - add mode_fixup feature. . hdmi module would change current mode to driver desired mode properly. - updated gem and buffer framework. . we can allocate physically continuous or non-continuous memory and also it creates scatterlist for iommu support so allocated memory region can be mapped to iommu page table using scatterlist. - add dma address get/put interface. . this function would be used for drm based 2d acceleration driver to get/put dma address through gem handle. when exynos_drm_get_dma_address is called reference count of gem object would be increased not to be released by gem close and when exynos_drm_put_dma_address is called the reference count of this gem object would be decreased to be released. - add virtual display driver. . this driver would be used for wireless display. - add direct rendering based 2d graphics acceleration module. . exynos SoC chip has fimg2d named 2d graphics accelerator and this driver supports only exynos4x12 series. Links to previous versions of the patchset: v1: < http://permalink.gmane.org/gmane.comp.video.dri.devel/66247 > Changelog v2: - add HDMI Audio support. - add descriptions for direct rendering based g2d driver and user application for it. . for user application, you can refer to this link below: http://www.spinics.net/lists/dri-devel/msg20014.html - fix variable type Dave pointed out. . use __u64 __user * instead of void * - code clean to exynos gem and buffer framework. - add default pixel format for plane. this patch set is based on git repository below: git://people.freedesktop.org/~airlied/linux.git drm-core-next commit-id: 8229c885fe361e521ac64de36b16011e54a30de0 and you can refer to our working git repository below: git://git.infradead.org/users/kmpark/linux-samsung exynos-drm-next Thanks.

Why do flush page cache twice when change TT's cache attribute
by Scott Fang 21 Mar '12

21 Mar '12

In function ttm_tt_set_caching ,,,,,,, if (ttm->caching_state == tt_cached) drm_clflush_pages(ttm->pages, ttm->num_pages); for (i = 0; i < ttm->num_pages; ++i) { cur_page = ttm->pages[i]; if (likely(cur_page != NULL)) { ret = ttm_tt_set_page_caching(cur_page, ttm->caching_state, c_state); if (unlikely(ret != 0)) goto out_err; } } ttm->caching_state = c_state; return 0; drm_clflush_pages flush cache one time. then in the following function ttm_tt_set_page_caching->set_memory_wc->change_page_attr_set: in this function may flush page cache again. Does the code do some abundant flush, or there is some trick to these codes? Thanks for the answer in advance.
