2020-05-05drm/mm: optimize rb_hole_addr rbtree searchNirmoy Das2-19/+115
Userspace can severely fragment rb_hole_addr rbtree by manipulating alignment while allocating buffers. Fragmented rb_hole_addr rbtree would result in large delays while allocating buffer object for a userspace application. It takes long time to find suitable hole because if we fail to find a suitable hole in the first attempt then we look for neighbouring nodes using rb_prev()/rb_next(). Traversing rbtree using rb_prev()/rb_next() can take really long time if the tree is fragmented. This patch improves searches in fragmented rb_hole_addr rbtree by modifying it to an augmented rbtree which will store an extra field in drm_mm_node, subtree_max_hole. Each drm_mm_node now stores maximum hole size for its subtree in drm_mm_node->subtree_max_hole. Using drm_mm_node->subtree_max_hole, it is possible to eliminate a complete subtree if that subtree is unable to serve a request hence reducing number of rb_prev()/rb_next() used. With this patch applied, 1 million bo allocs on amdgpu took ~8 sec, compared to 50k bo allocs which took 28 sec without it. partial test code: int test_fragmentation(void) { int i = 0; uint32_t minor_version; uint32_t major_version; struct amdgpu_bo_alloc_request request = {}; amdgpu_bo_handle vram_handle[MAX_ALLOC] = {}; amdgpu_device_handle device_handle; request.alloc_size = 4096; request.phys_alignment = 8192; request.preferred_heap = AMDGPU_GEM_DOMAIN_VRAM; int fd = open("/dev/dri/card0", O_RDWR | O_CLOEXEC); amdgpu_device_initialize(fd, &major_version, &minor_version, &device_handle); for (i = 0; i < MAX_ALLOC; i++) { amdgpu_bo_alloc(device_handle, &request, &vram_handle[i]); } for (i = 0; i < MAX_ALLOC; i++) amdgpu_bo_free(vram_handle[i]); return 0; } v2: Use RB_DECLARE_CALLBACKS_MAX to maintain subtree_max_hole v3: insert_hole_addr() should be static a function fix return value of next_hole_high_addr()/next_hole_low_addr() Reported-by: kbuild test robot <[email protected]> v4: Fix commit message.

The Amlogic S805X/Y uses the same die as the S905X, but with more limited graphics capabilities. This adds a soc version detection adding specific limitations on the HDMI mode selections. Here, we limit to HDMI 1.2a max HDMI PHY clock frequency. Changes sinces v1: - Moved frequency check in the vclk code, and also checks DMT modes Signed-off-by: Neil Armstrong <[email protected]> Acked-by: Martin Blumenstingl <[email protected]> [narmstrong: fixed commit message with HDMI 1.2a instead of HDMI 1.3a] Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-05-05drm/bridge: chrontel-ch7033: Add a new driverLubomir Rintel3-0/+631
This is a driver for video encoder with VGA and DVI/HDMI outputs. There is no documentation for the chip -- the operation was guessed from what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names come from the ch7035 driver in Mediatek's GPL code dump. Only bare minimum is implemented -- no fancy stuff, such as scaling. That would only worsen our misery. We don't load the firmware and we don't need to even bother enabling the MCU. There are probably no distributable firmware images anyway. Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60, with VGA as well as DVI.
