SR-IOV need to exchange some data between PF&VF through shared VRAM PF will copy some necessary firmware and information to the shared VRAM. It also requires some information from VF. PF will send a key through mailbox2 to help guest calculate checksum so that it can verify whether the data is correct. So check the data on the specified offset of the shared VRAM, if the checksum is right, read values from it and write some VF information next to the data from PF.

2017-10-16drm/sun4i: hdmi: Move PAD_CTRL1 setting to mode_set functionChen-Yu Tsai1-10/+16
Initially we configured the PAD_CTRL1 register at probe/bind time. However it seems the HDMI controller will modify some of the bits in this register by itself. On the A10 it is particularly annoying as it toggles the output invert bits, which inverts the colors on the display output. The U-boot driver this driver is based on sets this register twice, though it seems it's only needed for actual display output. Hence we move it to the mode_set function.

While debugging inverted color from the HDMI output on the A10, I found that the lowest 3 bits were set. These were cleared on A20 boards that had normal display output. By manually toggling these bits the mapping of the color components to these bits was found. While these are not used anywhere, it would be nice to document them somewhere.

2017-10-16drm/sun4i: backend: Add comment explaining why registers are clearedChen-Yu Tsai1-1/+8
Many of the backend's layer configuration registers have undefined default values. This poses a risk as we use regmap_update_bits in some places, and don't overwrite the whole register. At probe/bind time we explicitly clear all the control registers by writing 0 to them. This patch adds a more detailed explanation on why we're doing this.

2017-10-16drm/sun4i: don't add components that are already in the queueChen-Yu Tsai1-0/+16
Even though the components framework can handle duplicate entries, the extra entries cause a lot more debug messages to be generated, which would be confusing to developers not familiar with our driver and the framework in general. Instead, we can scan the relatively small queue and check if the component to be added is already queued up. Since the display pipelines are symmetrical (not considering the third display pipeline on the A80), and we add components level by level, when we get to the second instance at the same level, any shared downstream components would already be in the queue.

drm-next Most notable addition this time is the support for the GPU performance counters by Christian. This has been in the making for some time and it has matured a lot. Since this is adding UAPI, the corresponding WIP userspace can be found at [1] mesa/libdrm repos. I expect that Christian sends out the final userspace patches for this once you have pulled the kernel bits.

2017-10-13drm/tilcdc: Remove redundant OF_DETACHED flag settingStephen Boyd1-1/+0
of_fdt_unflatten_tree() already sets the flag on this node to OF_DETACHED, because of_fdt_unflatten_tree() calls __unflatten_device_tree() with the detached bool set to true.

2017-10-13drm/tilcdc: Precalculate total frametime in tilcdc_crtc_set_mode()Jyri Sarha1-1/+12
We need the total frame refresh time to check if we are too close to vertical sync when updating the two framebuffer DMA registers and risk a collision. This new method is more accurate that the previous that based on mode's vrefresh value, which itself is inaccurate or may not even be initialized.

2017-10-13drm: vblank: remove drm_timestamp_monotonic parameterArnd Bergmann3-25/+7
There is a risk of overflowing vblank timestamps in 2038 or 2106 if someone sets the drm_timestamp_monotonic module parameter to zero. I found no indication of anyone ever setting the parameter, or complaining about the default being wrong, after it was introduced as a way to handle backwards-compatibility with linux prior to c61eef726a78 ("drm: add support for monotonic vblank timestamps"), so it's probably safer to just remove the parameter completely and only allowing the default behavior.
