[PATCH] drm/tegra: remove unused variable
by Arnd Bergmann 09 Feb '16

09 Feb '16

A newly merged patch removed the only user of this variable, leading to a harmless gcc warning: drivers/gpu/drm/tegra/drm.c: In function 'tegra_drm_preclose': drivers/gpu/drm/tegra/drm.c:861:19: error: unused variable 'crtc' [-Werror=unused-variable] This removes the variable as well.

BUG caused by "Use new drm_fb_helper functions" series
by Peter Hurley 09 Feb '16

09 Feb '16

Hi Archit, Just booting 4.4-rc5+, I got this splat [1] At first glance, this appears to be a simple fix. However, I'm concerned that fbcon functions, which may be called with interrupts disabled, are now hooked up to fbdev functions which may assume interrupts are not disabled (as is the case with cfb_imageblit()). For example, in the splat below, it's a simple fix to make the splat go away with GFP_ATOMIC allocation. However, the following fence wait is _never_ going to trigger with interrupts disabled on UP. FWIW, I've been running almost exclusively debug kernel builds so I'm not sure why this hasn't triggered many times before, but it hasn't. Regards, Peter Hurley [1] BUG splat [ 37.438494] BUG: sleeping function called from invalid context at /home/peter/src/kernels/mainline/mm/slub.c:1287 [ 37.438495] in_atomic(): 1, irqs_disabled(): 1, pid: 2276, name: auditd [ 37.438497] 1 lock held by auditd/2276: [ 37.438507] #0: (audit_cmd_mutex){+.+.+.}, at: [<ffffffff8113a63f>] audit_receive+0x1f/0xa0 [ 37.438507] irq event stamp: 1689 [ 37.438511] hardirqs last enabled at (1689): [<ffffffff810e9a96>] vprintk_emit+0x236/0x620 [ 37.438513] hardirqs last disabled at (1688): [<ffffffff810e9934>] vprintk_emit+0xd4/0x620 [ 37.438518] softirqs last enabled at (1652): [<ffffffff81753898>] netlink_poll+0x138/0x1c0 [ 37.438520] softirqs last disabled at (1650): [<ffffffff81753857>] netlink_poll+0xf7/0x1c0 [ 37.438522] CPU: 7 PID: 2276 Comm: auditd Not tainted 4.4.0-rc5+wip-xeon+debug #rc5+wip [ 37.438523] Hardware name: Dell Inc.

[PATCH] drm/i915/skl: Fix typo in DPLL_CFGCR1 definition
by Lyude 09 Feb '16

09 Feb '16

We accidentally point both cfgcr registers for the second shared DPLL to the same location in i915_reg.h. This results in a lot of hw pipe state mismatches whenever we try to do a modeset that requires allocating the DPLL to a CRTC: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in dpll_hw_state.cfgcr1 (expected 0x80000168, found 0x000004a5) [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in base.adjusted_mode.crtc_clock (expected 108000, found 49500) [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in port_clock (expected 108000, found 49500) This usually ends up causing blank monitors, since the DPLL never can get set to the right clock.

by Lyude 09 Feb '16

We don't actually check for INTEL_OUTPUT_DP_MST at all in here, as a result we skip assigning a DPLL to any DP MST ports, which makes link training fail, after which things just keep going downhill from there.
