Update the state before sending the msg to close it. v2: reset value if return indicates we haven't send the msg. v3: just clean the code up. Pointed out by Adam J Richter on Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91481Reviewed-by:

output ports should always have a connector, unless in the rare case connector allocation fails in the driver. In this case we only need to teardown the pdt, and free the struct, and there is no need to send a hotplug msg. In the case were we add the port to the destroy list we need to send a hotplug if we destroy any connectors, so userspace knows to reprobe stuff. this patch also handles port->connector allocation failing which should be a rare event, but makes the code consistent.

This is unnecessary and it makes it easier to see what is needed from port. also add blank line to make things nicer. Reviewed-by:

drm_kms_helper_poll_enable() is called from a context in intel_hpd_irq_storm_disable() where the the mode_config mutex is already locked. When this function was converted to lock this mutex in commit 8c4ccc4a ("drm/probe-helper: Grab mode_config.mutex in poll_init/enable") a deadlock occurred. Call the newly implemented non-locking version of this function. Changes since v1: - use function name suffix '_locked' for the function that is to be called from a locked context. Signed-off-by:

When we're out of command buffer space, we turn on the command buffer processed irq without re-checking for finished command buffers afterwards. This might lead to a missed irq and the command submission process waiting forever for space. Fix this by rerunning the command buffer submission handler whenever we're out of command space. This ensures both that we don't needlessly turn on the irq, and that if we decide to turn on the irq, we recheck for finished command buffers before going to sleep. Reported-and-tested-by:

When obj->import_attach is existed, code calling drm_prime_gem_destroy() was removed from commit 67e93c80 ("drm/exynos: stop copying sg table"), and it's a fault. The drm_prime_gem_destroy() is cleanup function which GEM drivers need to call when they use drm_gem_prime_import() to import dma-bufs, so exynos-drm driver using drm_gem_prime_import() needs calling drm_prime_gem_destroy().

A previous commit resets the Context Status Buffer (CSB) read pointer in ring init commit c0a03a2e ("drm/i915: Reset CSB read pointer in ring init") This is generally correct, but this pointer is not reset after suspend/resume in some platforms (cht). In this case, the driver should read the register value instead of resetting the sw read counter to 0. Otherwise we process old events, leading to unwanted pre-emptions or something worse. But in other platforms (bdw) and also during GPU reset or power up, the CSBWP is reset to 0x7 (an invalid number), and in this case the read pointer should be set to 5 (the interrupt code will increment this counter one more time, and will start reading from CSB[0]). v2: When the CSB registers are reset, the read pointer needs to be set to 5, otherwise the first write (CSB[0]) won't be read (Mika). Replace magic numbers with GEN8_CSB_ENTRIES (6) and GEN8_CSB_PTR_MASK (0x07).
