https://bugzilla.kernel.org/show_bug.cgi?id=82581 --- Comment #2 from Christoph Haag <haagch.christoph@xxxxxxxxxxxxxx> --- It helps for the issue of increasing. But now it always returns 100. I don't think the HD 7970M has 100 compute units. http://www.amd.com/de-de/products/graphics/notebook/7900m#2 says "20 Compute Units (1280 Stream Processors)" To see how it adds up to 100 I added some debug info like this: printk("rdbg max_shader_engines: %d\n", rdev->config.si.max_shader_engines); printk("rdbg max_sh_per_se: %d\n", rdev->config.si.max_sh_per_se); printk("rdbg max_cu_per_sh: %d\n", rdev->config.si.max_cu_per_sh); for (i = 0; i < rdev->config.si.max_shader_engines; i++) { for (j = 0; j < rdev->config.si.max_sh_per_se; j++) { for (k = 0; k < rdev->config.si.max_cu_per_sh; k++) { rdev->config.si.active_cus += hweight32(si_get_cu_active_bitmap(rdev, i, j)); printk("rdbg inner: rdev->config.si.active_cus: %d, hweight32(si_get_cu_active_bitmap(rdev, %d, %d)): %d\n", rdev->config.si.active_cus, i, j, hweight32(si_get_cu_active_bitmap(rdev, i, j))); } } } And then I got this output: rdbg max_shader_engines: 2 rdbg max_sh_per_se: 2 rdbg max_cu_per_sh: 5 rdbg inner: rdev->config.si.active_cus: 5, hweight32(si_get_cu_active_bitmap(rdev, 0, 0)): 5 rdbg inner: rdev->config.si.active_cus: 10, hweight32(si_get_cu_active_bitmap(rdev, 0, 0)): 5 rdbg inner: rdev->config.si.active_cus: 15, hweight32(si_get_cu_active_bitmap(rdev, 0, 0)): 5 rdbg inner: rdev->config.si.active_cus: 20, hweight32(si_get_cu_active_bitmap(rdev, 0, 0)): 5 rdbg inner: rdev->config.si.active_cus: 25, hweight32(si_get_cu_active_bitmap(rdev, 0, 0)): 5 rdbg inner: rdev->config.si.active_cus: 30, hweight32(si_get_cu_active_bitmap(rdev, 0, 1)): 5 rdbg inner: rdev->config.si.active_cus: 35, hweight32(si_get_cu_active_bitmap(rdev, 0, 1)): 5 rdbg inner: rdev->config.si.active_cus: 40, hweight32(si_get_cu_active_bitmap(rdev, 0, 1)): 5 rdbg inner: rdev->config.si.active_cus: 45, hweight32(si_get_cu_active_bitmap(rdev, 0, 1)): 5 rdbg inner: rdev->config.si.active_cus: 50, hweight32(si_get_cu_active_bitmap(rdev, 0, 1)): 5 rdbg inner: rdev->config.si.active_cus: 55, hweight32(si_get_cu_active_bitmap(rdev, 1, 0)): 5 rdbg inner: rdev->config.si.active_cus: 60, hweight32(si_get_cu_active_bitmap(rdev, 1, 0)): 5 rdbg inner: rdev->config.si.active_cus: 65, hweight32(si_get_cu_active_bitmap(rdev, 1, 0)): 5 rdbg inner: rdev->config.si.active_cus: 70, hweight32(si_get_cu_active_bitmap(rdev, 1, 0)): 5 rdbg inner: rdev->config.si.active_cus: 75, hweight32(si_get_cu_active_bitmap(rdev, 1, 0)): 5 rdbg inner: rdev->config.si.active_cus: 80, hweight32(si_get_cu_active_bitmap(rdev, 1, 1)): 5 rdbg inner: rdev->config.si.active_cus: 85, hweight32(si_get_cu_active_bitmap(rdev, 1, 1)): 5 rdbg inner: rdev->config.si.active_cus: 90, hweight32(si_get_cu_active_bitmap(rdev, 1, 1)): 5 rdbg inner: rdev->config.si.active_cus: 95, hweight32(si_get_cu_active_bitmap(rdev, 1, 1)): 5 rdbg inner: rdev->config.si.active_cus: 100, hweight32(si_get_cu_active_bitmap(rdev, 1, 1)): 5 I think the k loop is already iterating over the compute units, but instead of 1 unit being added to the total, the result of si_get_cu_active_bitmap is added, which also seems to add up the compute units. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
