The framebuffer pitch and alignment constraints reflect the limitations of the Gen2 DU hardware. On Gen3, the DU has no memory interface and thus doesn't impose any constraint. The limitations come instead from the VSP that has a limit of 65535 bytes for the pitch and no alignment constraint. Update the checks accordingly. Signed-off-by:

The ESCR and OTAR registers exist in each DU channel, but at different offsets for odd and even channels. This led to usage of the group register access API to write them, with offsets macros named ESCR/OTAR and ESCR2/OTAR2 for the first and second ESCR/OTAR register in the group respectively. The names are confusing as it suggests that the ESCR/OTAR registers for DU0 and DU2 are taken into account, especially with writes performed to the group register access API. Rename the offsets to ESCR/OTAR02 and ESCR/OTAR13, and use the CRTC register access API to clarify the code. The offsets values are updated accordingly. Cosmetic patch, no functional changes intended. Signed-off-by:

DU channels not equipped with a DPLL use an SoC internal (provided by the CPG) or external clock source combined with a DU internal divider to generate the desired output dot clock frequency. The current clock selection procedure does not fully exploit the ability of external clock sources to generate the exact dot clock frequency by themselves, but relies instead on tuning the internal DU clock divider only, resulting in a less precise clock generation process. When possible, and desirable, ask the external clock source for the exact output dot clock frequency, and select the clock source that produces the frequency closest to the desired output dot clock. This patch specifically targets platforms (like Salvator-X[S] and ULCBs) where the DU's input dotclock.in is generated by the versaclock VC5 clock source, which is capable of generating the exact rate the DU needs as pixel clock output. This patch fixes higher resolution modes which requires an high pixel clock output currently not working on non-HDMI DU channel (such as 1920x1080@60Hz on the VGA output).

The DU channels that have a display PLL (DPLL) can only use external clock sources, and don't have an internal clock divider (with the exception of H3 ES1.x where the post-divider is present and needs to be used as a workaround for a DPLL silicon issue). Rework the clock configuration to take this into account, avoiding selection of non-existing clock sources or usage of a missing post-divider. Signed-off-by:

Use the newly exposed VSP1 interface to enable interlaced frame support through the VSP1 LIF pipelines. The DSMR register is updated to set the ODEV flag on interlaced pipelines, thus defining an interlaced stream as having the ODD field located in the second half (BOTTOM) of the frame buffer.

The Analogix DP bridge driver is pretty verbose, and outputs things like [ 619.414067] rockchip-dp ff970000.edp: Link Training Clock Recovery success [ 619.429233] rockchip-dp ff970000.edp: Link Training success! each time the display gets unblanked. While it is good to know that the device is behaving correctly, users already know that because they can see some video output. Let's keep these messages for cases where we need to actually debug the driver (we have dynamic debug to enable them at runtime if need be), and let's keep the kernel quiet otherwise. Signed-off-by:

Having DRM_SUN4I built-in but DRM_SUN8I_MIXER as a loadable module results in a link error, as we try to access a symbol from the sun8i_tcon_top.ko module: ERROR: "sun8i_tcon_top_de_config" [drivers/gpu/drm/sun4i/sun4i-tcon.ko] undefined! ERROR: "sun8i_tcon_top_set_hdmi_src" [drivers/gpu/drm/sun4i/sun4i-tcon.ko] undefined! ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun4i-tcon.ko] undefined! This solves the problem by adding a silent symbol for the tcon_top module, building it as a separate module in exactly the cases that we need it, but in a way that it is reachable by the other modules.

Lots of code can be removed by relying on fb-helper: - "struct drm_framebuffer" moves to fb_helper.fb. - "struct drm_gem_object" moves to fb_helper.obj[0]. - "struct qxl_device" can be inferred as drm_fb_helper is embedded. - qxl_user_framebuffer_create -> drm_gem_fb_create. - qxl_user_framebuffer_destroy -> drm_gem_fb_destroy. - qxl_fbdev_destroy -> drm_fb_helper_fbdev_teardown + vfree(shadow). Remove unused code: - qxl_fbdev_qobj_is_fb, qxl_fbdev_set_suspend. - Unused fields of qxl_fbdev: delayed_ops, delayed_ops_lock, size. Misc notes: - The dirty callback is preserved as it is necessary to trigger update commands in the hw (the screen stays black otherwise). - No idea when .create_handle in drm_framebuffer_funcs is used, but use the same drm_gem_fb_create_handle to match drm_gem_fb_funcs. - I don't know why qxl_fb_find_or_create_single used to check for an existing framebuffer and removed that check to match other drivers. - Use of drm_fb_helper_fbdev_teardown also requires "info->fbdefio" to be dynamically allocated. Replace the existing defio config by drm_fb_helper_defio_init to accomodate this. Testing results: startx with fbdev, modesetting and qxl all seems to work. Tested also with CONFIG_DRM_FBDEV_EMULATION=n, fbdev obviously fails but others are fine. QEMU -spice and QEMU -spice with vdagent and multiple (resized) displays (via remote-viewer) also works. unbind vtconsole and rmmod has *not* regressed (i.e. it still trips on a use-after-free in qxl_check_idle via qxl_ttm_fini). Ideally setup/teardown is replaced by drm_fbdev_generic_setup as that would result in further code reduction, improve error handling (like not leaking shadow memory), but unfortunately QXL has no implementation for qxl_gem_prime_vmap.

For buffer sharing, use dma-buf instead. We can't set smem_start to 0 unconditionally since that's used by the fbdev mmap default implementation. And we have plenty of userspace which would like to keep that working. This might break legit userspace - if it does we need to look at a case-by-cases basis how to handle that. Worst case I expect overrides for only specific drivers, since anything remotely modern should be using dma-buf/prime now (which is about 7 years old now for DRM drivers). This issue was uncovered because Noralf's rework to implement a generic fb_probe also implements it's own fb_mmap callback. Which means smem_start didn't have to be set anymore, which blew up some blob in userspace rather badly. Acked-by:
