In order to reduce the time required to turn on the panel, this patch makes 2 assumptions: 1- In detect(): if there's a panel, we're connected. 2- In get_modes(): if there's a panel, let the panel driver decide if it should prepare/unprepare in order to get the modes. The first is straightforward, and shouldn't need further explanation. The second should eliminate the prepare/unprepare delays from get_modes() in most cases, since panels generally hardcode their modes in the driver as opposed to reading EDID. If a panel does need to read EDID, it should be responsible for ensuring it's in a state in which it can. Signed-off-by:Sean Paul <seanpaul@chromium.org>

If there's a panel connected to the analogix_dp bridge, rely on the panel driver for modes, rather than reading EDID *and* calling get_modes() on the panel. This allows panels with a valid EDID to read it in the panel driver (e.g. simple_panel), and panels with invalid EDID to homebrew modes in their get_modes implementation. Signed-off-by: -

Remove code for reading the EDID and DPCD fields and use the helpers instead. Besides the obvious code reduction, other helpers are being added to the core that could be used in this driver and will be good to be able to use them instead of duplicating them. Signed-off-by:

Turns out assuming that only stuff in uabi is uabi is a bit naive, and we have a bunch of properties for which the enum values are placed in random headers. A proper fix would be to split out uapi include headers, but meanwhile sprinkle at least some warning over them.

When merging sync_files there is a case when we can end up with only one fence in the merged sync_file: when all fences belong to the same timeline. So for this case a fence_array is not created instead we just assigned the fence to sync_file->fence. Then we do not use the fences array anymore nor does free it. This patch frees the array.

The connector shouldn't be registered until the rest of the whole device is set up, so that consistent state is presented to userspace. As drm_dev_register() now registers all of the connectors anyway, there's no need to explicitly do it in individual drivers so remove the calls to drm_connector_register()/drm_connector_unregister(). This allows componentised drivers to use tda998x without having racy initialisation. Signed-off-by:

Big thing is untangling and carefully documenting the different uapi types of planes. I also sprinkled a few more cross references around to make this easier to discover. As usual, remove the kerneldoc for internal functions which are not exported. Aside: We should probably go OCD on all the ioctl handlers and consistenly give them an _ioctl postfix. Acked-by:

When we merge several fences, if all of them are signaled already, we still keep one of them. So instead of using add_fence(), which will not increase the refcount of signaled fences, we should explicitly call fence_get() for the fence we are keeping. This patch fixes a kernel panic that can be triggered by creating a fence that is expired (or increasing the timeline until it expires), then creating a merged fence out of it, and deleting the merged fence. This will make the original expired fence's refcount go to zero. Testcase: igt/sw_sync/sync_expired_merge Signed-off-by:

Various cleanups to the DRM core initialization and exit handlers: - Register chrdev last: Once register_chrdev() returns, open() will succeed on the given chrdevs. This is usually not an issue, as no chardevs are registered, yet. However, nodes can be created by user-space via mknod(2), even though such major/minor combinations are unknown to the kernel. Avoid calling into drm_stub_open() in those cases. Again, drm_stub_open() would just bail out as the inode is unknown, but it's really non-obvious if you hack on drm_stub_open(). - Unify error-paths into just one label. All the error-path helpers can be called even though the constructors were not called yet, or failed. Hence, just call all cleanups unconditionally. - Call into drm_global_release(). This is a no-op, but provides debugging helpers in case there're GLOBALS left on module unload. This function was unused until now. - Use DRM_ERROR() instead of printk(), and also print the error-code on failure (even if it is static!). - Don't throw away error-codes of register_chrdev()! - Don't hardcode -1 as errno. This is just plain wrong. - Order exit-handlers in the exact reverse order of initialization (except if the order actually matters for syncing-reasons, which is not the case here, though). v2: - Call drm_core_exit() directly from the init-error-handler. Requires to drop __exit annotation, though. Signed-off-by:

The drm_core.h header contains a set of constants meant to be used throughout DRM. However, as it turns out, they're each used just once and don't bring any benefit. They're also grossly mis-named and lack name-spacing. This patch inlines them, or moves them into drm_internal.h as appropriate: - CORE_AUTHOR and CORE_DESC are inlined into corresponding MODULE_*() macros. It's just confusing having to follow 2 pointers when trying to find the definition of these fields. Grep'ping for MODULE_AUTHOR() should reveal the full information, if there's no strong reason not to. - CORE_NAME, CORE_DATE, CORE_MAJOR, CORE_MINOR, and CORE_PATCHLEVEL are inlined into the sysfs 'version' attribute. They're stripped everywhere else (which is just some printk() statements). CORE_NAME just doesn't make *any* sense, as we hard-code it in many places, anyway. The other constants are outdated and just serve binary-compatibility purposes. Hence, inline them in 'version' sysfs attribute (we might even try dropping it..). - DRM_IF_MAJOR and DRM_IF_MINOR are moved into drm_internal.h as they're only used by the global ioctl handlers. Furthermore, versioning interfaces breaks backports and as such is deprecated, anyway. We just keep them for historic reasons. I doubt anyone will ever modify them again. Signed-off-by:

Each DRM file-context caches the EUID of the process that opened the file. It is used exclusively for debugging purposes in /proc/dri/ and friends. Note, however, that we can already fetch the EUID from priv->pid->task->creds. The pointer-chasing will not hurt us, since it is only about debugging, anyway. Since we already are in an rcu-read-side, we can use __task_cred() rather than task_cred_xxx(). Signed-off-by:

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by:
