+ * intel_set_memory_cxsr - Configure CxSR state
+ * @dev_priv: i915 device
+ * @enable: Allow vs. disallow CxSR
+ *
+ * Allow or disallow the system to enter a special CxSR
+ * (C-state self refresh) state. What typically happens in CxSR mode
+ * is that several display FIFOs may get combined into a single larger
+ * FIFO for a particular plane (so called max FIFO mode) to allow the
+ * system to defer memory fetches longer, and the memory will enter
+ * self refresh.
+ *
+ * Note that enabling CxSR does not guarantee that the system enter
+ * this special mode, nor does it guarantee that the system stays
+ * in that mode once entered. So this just allows/disallows the system
+ * to autonomously utilize the CxSR mode. Other factors such as core
+ * C-states will affect when/if the system actually enters/exits the
+ * CxSR mode.
+ *
+ * Note that on VLV/CHV this actually only controls the max FIFO mode,
+ * and the system is free to enter/exit memory self refresh at any time
+ * even when the use of CxSR has been disallowed.
+ *
+ * While the system is actually in the CxSR/max FIFO mode, some plane
+ * control registers will not get latched on vblank. Thus in order to
+ * guarantee the system will respond to changes in the plane registers
+ * we must always disallow CxSR prior to making changes to those registers.
+ * Unfortunately the system will re-evaluate the CxSR conditions at
+ * frame start which happens after vblank start (which is when the plane
+ * registers would get latched), so we can't proceed with the plane update
+ * during the same frame where we disallowed CxSR.
+ *
+ * Certain platforms also have a deeper HPLL SR mode. Fortunately the
+ * HPLL SR mode depends on CxSR itself, so we don't have to hand hold
+ * the hardware w.r.t. HPLL SR when writing to plane registers.
+ * Disallowing just CxSR is sufficient.

-/**
- * intel_update_watermarks - update FIFO watermark values based on current modes
- * @dev_priv: i915 device
- *
- * Calculate watermark values for the various WM regs based on current mode
- * and plane configuration.
- *
- * There are several cases to deal with here:
- *   - normal (i.e. non-self-refresh)
- *   - self-refresh (SR) mode
- *   - lines are large relative to FIFO size (buffer can hold up to 2)
- *   - lines are small relative to FIFO size (buffer can hold more than 2
- *     lines), so need to account for TLB latency
- *
- *   The normal calculation is:
- *     watermark = dotclock * bytes per pixel * latency
- *   where latency is platform & configuration dependent (we assume pessimal
- *   values here).
- *
- *   The SR calculation is:
- *     watermark = (trunc(latency/line time)+1) * surface width *
- *       bytes per pixel
- *   where
- *     line time = htotal / dotclock
- *     surface width = hdisplay for normal plane and 64 for cursor
- *   and latency is assumed to be high, as above.
- *
- * The final value programmed to the register should always be rounded up,
- * and include an extra 2 entries to account for clock crossings.
- *
- * We don't use the sprite, so we can ignore that.  And on Crestline we have
- * to set the non-SR watermarks to 8.

+ *
+ * There are several cases to deal with here:
+ *   - normal (i.e. non-self-refresh)
+ *   - self-refresh (SR) mode
+ *   - lines are large relative to FIFO size (buffer can hold up to 2)
+ *   - lines are small relative to FIFO size (buffer can hold more than 2
+ *     lines), so need to account for TLB latency
+ *
+ *   The normal calculation is:
+ *     watermark = dotclock * bytes per pixel * latency
+ *   where latency is platform & configuration dependent (we assume pessimal
+ *   values here).
+ *
+ *   The SR calculation is:
+ *     watermark = (trunc(latency/line time)+1) * surface width *
+ *       bytes per pixel
+ *   where
+ *     line time = htotal / dotclock
+ *     surface width = hdisplay for normal plane and 64 for cursor
+ *   and latency is assumed to be high, as above.
+ *
+ * The final value programmed to the register should always be rounded up,
+ * and include an extra 2 entries to account for clock crossings.
+ *
+ * We don't use the sprite, so we can ignore that.  And on Crestline we have
+ * to set the non-SR watermarks to 8.

- * intel_set_memory_cxsr - Configure CxSR state
- * @dev_priv: i915 device
- * @enable: Allow vs. disallow CxSR
- *
- * Allow or disallow the system to enter a special CxSR
- * (C-state self refresh) state. What typically happens in CxSR mode
- * is that several display FIFOs may get combined into a single larger
- * FIFO for a particular plane (so called max FIFO mode) to allow the
- * system to defer memory fetches longer, and the memory will enter
- * self refresh.
- *
- * Note that enabling CxSR does not guarantee that the system enter
- * this special mode, nor does it guarantee that the system stays
- * in that mode once entered. So this just allows/disallows the system
- * to autonomously utilize the CxSR mode. Other factors such as core
- * C-states will affect when/if the system actually enters/exits the
- * CxSR mode.
- *
- * Note that on VLV/CHV this actually only controls the max FIFO mode,
- * and the system is free to enter/exit memory self refresh at any time
- * even when the use of CxSR has been disallowed.
- *
- * While the system is actually in the CxSR/max FIFO mode, some plane
- * control registers will not get latched on vblank. Thus in order to
- * guarantee the system will respond to changes in the plane registers
- * we must always disallow CxSR prior to making changes to those registers.
- * Unfortunately the system will re-evaluate the CxSR conditions at
- * frame start which happens after vblank start (which is when the plane
- * registers would get latched), so we can't proceed with the plane update
- * during the same frame where we disallowed CxSR.
- *
- * Certain platforms also have a deeper HPLL SR mode. Fortunately the
- * HPLL SR mode depends on CxSR itself, so we don't have to hand hold
- * the hardware w.r.t. HPLL SR when writing to plane registers.
- * Disallowing just CxSR is sufficient.

- * Compute the watermark using the method 2 or "large buffer"

- *
- * This method is concerned with the long term drain rate

- * a longer period. The name "large" refers to the fact the
- * FIFO is relatively large compared to the amount of data
- * fetched.
- *
- * The FIFO level vs. time graph might look something like:
- *
- *    |\___       |\___

- *    |        \  |        \
