[STABLE v4.14 PATCH] drm/i915: set DP Main Stream Attribute for color range on DDI platforms

by Jani Nikula

commit 6209c285e7a5e68dbcdf8fd2456c6dd68433806b upstream. Since Haswell we have no color range indication either in the pipe or port registers for DP. Instead, there's a separate register for setting the DP Main Stream Attributes (MSA) directly. The MSA register definition makes no references to colorimetry, just a vague reference to the DP spec. The connection to the color range was lost. Apparently we've failed to set the proper MSA bit for limited, or CEA, range ever since the first DDI platforms. We've started setting other MSA parameters since commit dae847991a43 ("drm/i915: add intel_ddi_set_pipe_settings"). Without the crucial bit of information, the DP sink has no way of knowing the source is actually transmitting limited range RGB, leading to "washed out" colors. With the colorimetry information, compliant sinks should be able to handle the limited range properly. Native (i.e. non-LSPCON) HDMI was not affected because we do pass the color range via AVI infoframes. Though not the root cause, the problem was made worse for DDI platforms with commit 55bc60db5988 ("drm/i915: Add "Automatic" mode for the "Broadcast RGB" property"), which selects limited range RGB automatically based on the mode, as per the DP, HDMI and CEA specs. After all these years, the fix boils down to flipping one bit. [Per testing reports, this fixes DP sinks, but not the LSPCON. My educated guess is that the LSPCON fails to turn the CEA range MSA into AVI infoframes for HDMI.] Reported-by: Michał Kopeć <mkopec12(a)gmail.com> Reported-by: N.

[PATCH 1/2] Drivers: hv: vmbus: Use get/put_cpu() in vmbus_connect()

by kys＠linuxonhyperv.com

From: Dexuan Cui <decui(a)microsoft.com> With CONFIG_DEBUG_PREEMPT=y, I always see this warning: BUG: using smp_processor_id() in preemptible [00000000] Fix the false warning by using get/put_cpu(). Here vmbus_connect() sends a message to the host and waits for the host's response. The host will deliver the response message and an interrupt on CPU msg->target_vcpu, and later the interrupt handler will wake up vmbus_connect(). vmbus_connect() doesn't really have to run on the same cpu as CPU msg->target_vcpu, so it's safe to call put_cpu() just here.

[PATCH] dm-mpath: Fix setup_scsi_dh()

by Bart Van Assche

This patch fixes two bugs that got introduced recently in setup_scsi_dh(): - Avoid that a memory leak occurs if attached_handler_name is not assigned to m->hw_handler_name. - Avoid that m->hw_handler_name becomes a dangling pointer if the RETAIN_ATTACHED_HW_HANDLER flag is set and scsi_dh_attach() returns -EBUSY.
