Since commit 9495b7e92f71 ("driver core: platform: Initialize dma_parms for platform devices"), struct platform_device already provides a dma_parms structure, so we can save allocating another one.

2020-09-10drm: msm: fix common struct sg_table related issuesMarek Szyprowski3-17/+13
The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function returns the number of the created entries in the DMA address space. However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and dma_unmap_sg must be called with the original number of the entries passed to the dma_map_sg(). struct sg_table is a common structure used for describing a non-contiguous memory buffer, used commonly in the DRM and graphics subsystems. It consists of a scatterlist with memory pages and DMA addresses (sgl entry), as well as the number of scatterlist entries: CPU pages (orig_nents entry) and DMA mapped pages (nents entry). It turned out that it was a common mistake to misuse nents and orig_nents entries, calling DMA-mapping functions with a wrong number of entries or ignoring the number of mapped entries returned by the dma_map_sg() function. To avoid such issues, lets use a common dma-mapping wrappers operating directly on the struct sg_table objects and use scatterlist page iterators where possible. This, almost always, hides references to the nents and orig_nents entries, making the code robust, easier to follow and copy/paste safe.

In TEST_ONLY commit, rm global_state will duplicate the object and request for new reservations, once they pass then the new state will be swapped with the old and will be available for the Atomic Commit. This patch fixes some of missing links in the resource reservation sequence mentioned above. 1) Creation of duplicate state in test_only commit (Rob) 2) Allocate and release the resources on every modeset. 3) Avoid allocation only when active is false. In a modeset operation, swap state happens well before disable. Hence clearing reservations in disable will cause failures in modeset enable. Allow reservations to be cleared/allocated before swap, such that only newly committed resources are pushed to HW. Changes in v1: - Move the rm release to atomic_check. - Ensure resource allocation and free happens when active is not changed i.e only when mode is changed.(Rob) Changes in v2: - Handle dpu_kms_get_global_state API failure as it may return EDEADLK (swboyd).

2020-07-31drm/msm: use kthread_create_worker instead of kthread_runBernard3-15/+8
Use kthread_create_worker to simplify the code and optimise the manager struct: msm_drm_thread. With this change, we could remove struct element (struct task_struct *thread & struct kthread_worker worker), instead, use one point (struct kthread_worker *worker).
