The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Instead of the DRM framebuffer, pass the FB info strcuture to the fbdev page-fault handler psb_fbdev_vm_fault(). The framebuffer is a high-level data structure and does not belong into fault handling. The fb_info has all necessary information. Also set fix.smem_start to the correct value (the beginning of the framebuffer in physical address space) and streamline the page-fault handler. v2: * remove unused struct drm_psb_private.fb_base (Patrik) Signed-off-by:

Implement fbdevemulation on top of struct drm_client and its helpers. This ad-hoc interfaces for restoring and closing fbdev emulation with per-client callback for hotplugging, restoring and unregistering. A single function, psb_fbdev_setup(), starts fbdev emulation after the DRM device has been registered. Hence, fbdev acts like a regular DRM client. The setup call only prepares the fbdev emulation. It then implements connector hotplugging. The first successful hotplug event initializes fbdev emulation. Unregistering depends on the hotplugging. Fully initialized emulation is cleaned up through drm_fb_helper_unregister_info() and fb_destroy. For prepared-only setups, unregistering unprepares the emulation and releases all resources. In both cases, fbdev emulation will be cleaned up. v2: * declare empty setup function as 'static inline' (kernel test robot) Signed-off-by:

When dynamically switching lanes was removed, the intent of the code was to check to make sure that higher speed items used 4 lanes, but it had the unintended consequence of removing the slower speeds for 4-lane users. This attempts to remedy this by doing a check to see that the max frequency doesn't exceed the chip limit, and a second check to make sure that the max bit-rate doesn't exceed the number of lanes * max bit rate / lane.

Thread group id (aka pid from userspace point of view) is a more interesting thing to show as an owner of a DRM fd, so track and show that instead of the thread id. In the next patch we will make the owner updated post file descriptor handover, which will also be tgid based to avoid ping-pong when multiple threads access the fd. Signed-off-by:

This driver has no way to handle damage, the reason the drm_gem_fb_create_with_dirty() was used was because I had the ambition that the driver would only send out updates to DSI command displays whenever something changed, so as to minimize traffic. It turns out this ambition with command mode isn't working in practice because all the MCDE does is to create a continuous stream of DSI commands and while it is possible to send single frame updates with it, it's not been worthwhile. So we are just setting up continuous updates. Reported-by:
