The current code only base its decision for whether the scrambler must be enabled or not on the pixel clock of the mode, but doesn't take the bits per color into account. Let's leverage the new function to compute the clock rate in the scrambler setup code. Signed-off-by:

In the function that validates that the clock isn't too high, we've only taken our controller limitations into account so far. However, the sink can have a limit on the maximum TMDS clock it can deal with too which is exposed through the EDID and the drm_display_info. Make sure we check it. Signed-off-by:

This function allows to replace fences from the shared fence list when we can gurantee that the operation represented by the original fence has finished or no accesses to the resources protected by the dma_resv object any more when the new fence finishes.

struct drm_display_mode embeds a list head, so overwriting the full struct with another one will corrupt the list (if the destination mode is on a list). Use drm_mode_copy() instead which explicitly preserves the list head of the destination mode. Even if we know the destination mode is not on any list using drm_mode_copy() seems decent as it sets a good example. Bad examples of not using it might eventually get copied into code where preserving the list head actually matters. Obviously one case not covered here is when the mode itself is embedded in a larger structure and the whole structure is copied. But if we are careful when copying into modes embedded in structures I think we can be a little more reassured that bogus list heads haven't been propagated in. @is_mode_copy@ @@ drm_mode_copy(...) { ... } @depends on !is_mode_copy@ struct drm_display_mode *mode; expression E, S; @@ ( - *mode = E + drm_mode_copy(mode, &E) | - memcpy(mode, E, S) + drm_mode_copy(mode, E) ) @depends on !is_mode_copy@ struct drm_display_mode mode; expression E; @@ ( - mode = E + drm_mode_copy(&mode, &E) | - memcpy(&mode, E, S) + drm_mode_copy(&mode, E) ) @@ struct drm_display_mode *mode; @@ - &*mode + mode Cc: Jyri Sarha <jyri.sarha@iki.fi> Cc: Tomi Valkeinen <tomba@kernel.org> Signed-off-by:Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>

With very limited vram on svga3 it's difficult to handle all the surface migrations. Without gbobjects, i.e. the ability to store surfaces in guest mobs, there's no reason to support intermediate svga2 features, especially because we can fall back to fb traces and svga3 will never support those in-between features. On svga3 we wither want to use fb traces or screen targets (i.e. gbobjects), nothing in between. This fixes presentation on a lot of fusion/esxi tech previews where the exposed svga3 caps haven't been finalized yet. Signed-off-by:

vmw_move assumed that buffers to be moved would always be vmw_buffer_object's but after introduction of new placement for mob pages that's no longer the case. The resulting invalid read didn't have any practical consequences because the memory isn't used unless the object actually is a vmw_buffer_object. Fix it by moving the cast to the spot where the results are used. Signed-off-by:

ssd130x_clear_screen() allocates a temporary buffer sized to hold one byte per pixel, while it only needs to hold one bit per pixel. ssd130x_fb_blit_rect() allocates a temporary buffer sized to hold one byte per pixel for the whole frame buffer, while it only needs to hold one bit per pixel for the part that is to be updated. Pass dst_pitch to drm_fb_xrgb8888_to_mono(), as we have already calculated it anyway. Fixes: a61732e8 ("drm: Add driver for Solomon SSD130x OLED displays") Signed-off-by:

The rectangle update functions ssd130x_fb_blit_rect() and ssd130x_update_rect() do not behave correctly when x1 != 0 or y1 != 0, or when y1 or y2 are not aligned to display page boundaries. E.g. when used as a text console, only the first line of text is shown on the display. 1. The buffer passed by ssd130x_fb_blit_rect() points to the first byte of monochrome bitmap data, and thus has its origin at (x1, y1), while ssd130x_update_rect() assumes it is at (0, 0). Fix ssd130x_update_rect() by changing the vertical and horizontal loop ranges, and adding the offsets only when needed. 2. In ssd130x_fb_blit_rect(), align y1 and y2 to the display page boundaries before doing the color conversion, so the full page is converted and updated. Remove the correction for an unaligned y1 from ssd130x_update_rect(), and add a check to make sure y1 is aligned.

The conversion functions drm_fb_xrgb8888_to_mono() and drm_fb_gray8_to_mono_line() do not behave correctly when the horizontal boundaries of the clip rectangle are not multiples of 8: a. When x1 % 8 != 0, the calculated pitch is not correct, b. When x2 % 8 != 0, the pixel data for the last byte is wrong. Simplify the code and fix (a) by: 1. Removing start_offset, and always storing the first pixel in the first bit of the monochrome destination buffer. Drivers that require the first pixel in a byte to be located at an x-coordinate that is a multiple of 8 can always align the clip rectangle before calling drm_fb_xrgb8888_to_mono(). Note that: - The ssd130x driver does not need the alignment, as the monochrome buffer is a temporary format, - The repaper driver always updates the full screen, so the clip rectangle is always aligned. 2. Passing the number of pixels to drm_fb_gray8_to_mono_line(), instead of the number of bytes, and the number of pixels in the last byte. Fix (b) by explicitly setting the target bit, instead of always setting bit 7 and shifting the value in each loop iteration. Remove the bogus pitch check, which operates on bytes instead of pixels, and triggers when e.g. flashing the cursor on a text console with a font that is 8 pixels wide. Drop the confusing comment about scanlines, as a pitch in bytes always contains a multiple of 8 pixels. While at it, use the drm_rect_height() helper instead of open-coding the same operation. Update the comments accordingly. Fixes: bcf8b616 ("drm/format-helper: Add drm_fb_xrgb8888_to_mono_reversed()") Signed-off-by:Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by:

There is no "reversed" handling in drm_fb_xrgb8888_to_mono_reversed(): the function just converts from color to grayscale, and reduces the number of grayscale levels from 256 to 2 (i.e. brightness 0-127 is mapped to 0, 128-255 to 1). All "reversed" handling is done in the repaper driver, where this function originated. Hence make this clear by renaming drm_fb_xrgb8888_to_mono_reversed() to drm_fb_xrgb8888_to_mono(), and documenting the black/white pixel mapping.
