+Synopsis:
+
+How to address an intermittent problem observed on some GK104-based products.
+
+Description:
+
+A diagnostic setting was inadvertently left enabled in the production VBIOS
+builds on some NVIDIA GK104-based graphics cards.  This setting can result in a
+red screen being displayed in some rare cases, for example in response to
+certain mode-set operations.
+
+The setting in question is used as part of the product engineering process to
+make display engine underflows more easily human-detectable.  This is a scenario
+in which the bandwidth provided by the GPU's video memory interface, in the
+current performance state (at relevant clock frequencies defined by this state),
+is insufficient to satisfy the current isochronous streaming requirements of the
+display engine.
+
+The NVIDIA Accelerated Linux Graphics Driver disables this setting when it
+initializes the GPU.  However, it is NVIDIA's suggestion that independently
+developed drivers also disable it.
+
+Workaround:
+
+The underflow detection setting can be disabled by means of the per-head
+register NV_PDISP_RG_UNDERFLOW(i), accessible via the GPUs' BAR0 (where 'i' is
+the head index):
+
+  NV_PDISP_RG_UNDERFLOW(i) (0x00616308 + (i) * 2048) 
+
+Since the affected GPUs implement four heads, four such registers are
+available. To disable the underflow detection, the registers need to be
+programmed with the value 0. 
+
+Scope:
+
+The problem described above affects GK104-based products with VBIOS versions
+below 80.04.63.00.00.  This includes (but may not be limited to) the following
+products:

+
+Register Description:
+
+This register is used for detecting underflows and also determines what action
+the hw should take when an underflow occurs.
+
+ENABLE Turns on underflow reporting. Note that this has no effect on the
+underflow mode. The underflow mode (what to do when an underflow occurs, REPEAT
+or RED, is always active).
+
+UNDERFLOWED Indicates whether an underflow has occurred. This is a "sticky" bit.
+To clear it, software writes a '1' to this bit.  UNDERFLOWED is active
+only when the above ENABLE bit is set.
+
+UNDERFLOW_MODE Indicates what to do when an underflow occurs. If REPEAT
+is set, then the raster generator will repeat the last pixel, when a new
+pixel is not available. If RED is set, the raster generator will display
+bright red for any missing pixels.
