The variable bit_per_pix is a u8 and is promoted in the multiplication to an int type and then sign extended to a u64. If the result of the int multiplication is greater than 0x7fffffff then the upper 32 bits will be set to 1 as a result of the sign extension. Avoid this by casting tu_size_reg to u64 to avoid sign extension and also a potential overflow. Fixes: 1a0f7ed3 ("drm/rockchip: cdn-dp: add cdn DP support for rk3399") Signed-off-by:

commit cf6d100d ("drm/rockchip: dsi: add dual mipi support") added this devcnt field and call to component_del(). However, these both appear to be erroneous changes left over from an earlier version of the patch. In the version merged, nothing ever modifies devcnt, meaning component_del() runs unconditionally and in addition to the component_del() calls in dw_mipi_dsi_rockchip_host_detach(). The second call fails to delete anything and produces a warning in dmesg. If we look at the previous version of the patch[1], however, we see that it had logic to calculate devcnt and call component_add() in certain situations. This was removed in v6, and the fact that the deletion code was not appears to have been an oversight.

When we first enable the DSI encoder, we currently program some per-chip configuration that we look up in rk3399_chip_data based on the device tree compatible we match. This data configures various parameters of the MIPI lanes, including on RK3399 whether DSI1 is slaved to DSI0 in a dual-mode configuration. It also selects which LCDC (i.e. VOP) to scan out from. This causes a problem in RK3399 dual-mode configurations, though: panel prepare() callbacks run before the encoder gets enabled and expect to be able to write commands to the DSI bus, but the bus isn't fully functional until the lane and master/slave configuration have been programmed. As a result, dual-mode panels (and possibly others too) fail to turn on when the rockchipdrm driver is initially loaded. Because the LCDC mux is the only thing we don't know until enable time (and is the only thing that can ever change), we can actually move most of the initialization to bind() and get it out of the way early. That's what this change does. (Rockchip's 4.4 BSP kernel does it in mode_set(), which also avoids the issue, but bind() seems like the more correct place to me.) Tested on a Google Scarlet board (Acer Chromebook Tab 10), which has a Kingdisplay KD097D04 dual-mode panel. Prior to this change, the panel's backlight would turn on but no image would appear when initially loading rockchipdrm. If I kept rockchipdrm loaded and reloaded the panel driver, it would come on. With this change, the panel successfully turns on during initial rockchipdrm load as expected. Fixes: 2d4f7bda ("drm/rockchip: dsi: migrate to use dw-mipi-dsi bridge driver") Signed-off-by:

There are drivers that register framebuffer devices very early in the boot process and make use of the existing framebuffer as setup by the firmware. If one of those drivers has registered a fbdev, then the fallback fbdev of the DRM driver won't be bound to the framebuffer console. To avoid that, remove any existing generic driver and take over the graphics device. By doing that, the fb mapped to the console is switched correctly from the early fbdev to the one registered by the rockchip DRM driver: [ 40.752420] fb0: switching to rockchip-drm-fb from EFI VGA Signed-off-by:Javier Martinez Canillas <javierm@redhat.com> Signed-off-by:

The previous commit wrongly assumed that dma_mmap_wc() could be replaced by pgprot_writecombine() + dma_mmap_pages(). It did work on my setup, but did not work everywhere. Use dma_mmap_wc() when the buffer has the write-combine cache attribute, and dma_mmap_pages() when it has the non-coherent cache attribute. Signed-off-by:

Framebuffer devices that are registered by DRM drivers for fbdev emulation have a "drmfb" suffix in their name. But makes them to be quite confusing for drivers that already have "drm" in their name: $ cat /proc/fb 0 rockchipdrmdrmfb $ cat /proc/fb 0 simpledrmdrmfb Also, there isn't a lot of value in adding these "drmfb" suffices to their names, since users shouldn't really care if the FB devices were registered by a real fbdev driver or a DRM driver using the fbdev emulation. What programs should be interested about is if there's a DRM device, and there are better ways to query that info than reading this procfs entry. So let's just remove the suffix, which leads to much better device names: $ cat /proc/fb 0 rockchipdrm $ cat /proc/fb 0 simpledrm Suggested-by:

Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. This change resolves several inconsistencies between regular mmap and prime-based mmap. The vm_ops field in vma is now set for all mmap'ed areas. Previously it way only set for regular mmap calls, prime-based mmap used TTM's default vm_ops. The function amdgpu_verify_access() is no longer being called and therefore removed by this patch.
