- *
- * This is an interface to the NX-842 compression hardware in PowerPC
- * processors.  Most of the complexity of this drvier is due to the fact that
- * the NX-842 compression hardware requires the input and output data buffers
- * to be specifically aligned, to be a specific multiple in length, and within
- * specific minimum and maximum lengths.  Those restrictions, provided by the
- * nx-842 driver via nx842_constraints, mean this driver must use bounce
- * buffers and headers to correct misaligned in or out buffers, and to split
- * input buffers that are too large.
- *
- * This driver will fall back to software decompression if the hardware
- * decompression fails, so this driver's decompression should never fail as
- * long as the provided compressed buffer is valid.  Any compressed buffer
- * created by this driver will have a header (except ones where the input
- * perfectly matches the constraints); so users of this driver cannot simply
- * pass a compressed buffer created by this driver over to the 842 software
- * decompression library.  Instead, users must use this driver to decompress;
- * if the hardware fails or is unavailable, the compressed buffer will be
- * parsed and the header removed, and the raw 842 buffer(s) passed to the 842
- * software decompression library.
- *
- * This does not fall back to software compression, however, since the caller
- * of this function is specifically requesting hardware compression; if the
- * hardware compression fails, the caller can fall back to software
- * compression, and the raw 842 compressed buffer that the software compressor
- * creates can be passed to this driver for hardware decompression; any
- * buffer without our specific header magic is assumed to be a raw 842 buffer
- * and passed directly to the hardware.  Note that the software compression
- * library will produce a compressed buffer that is incompatible with the
- * hardware decompressor if the original input buffer length is not a multiple
- * of 8; if such a compressed buffer is passed to this driver for
- * decompression, the hardware will reject it and this driver will then pass
- * it over to the software library for decompression.

+ *
+ * This is an interface to the NX-842 compression hardware in PowerPC
+ * processors.  Most of the complexity of this drvier is due to the fact that
+ * the NX-842 compression hardware requires the input and output data buffers
+ * to be specifically aligned, to be a specific multiple in length, and within
+ * specific minimum and maximum lengths.  Those restrictions, provided by the
+ * nx-842 driver via nx842_constraints, mean this driver must use bounce
+ * buffers and headers to correct misaligned in or out buffers, and to split
+ * input buffers that are too large.
+ *
+ * This driver will fall back to software decompression if the hardware
+ * decompression fails, so this driver's decompression should never fail as
+ * long as the provided compressed buffer is valid.  Any compressed buffer
+ * created by this driver will have a header (except ones where the input
+ * perfectly matches the constraints); so users of this driver cannot simply
+ * pass a compressed buffer created by this driver over to the 842 software
+ * decompression library.  Instead, users must use this driver to decompress;
+ * if the hardware fails or is unavailable, the compressed buffer will be
+ * parsed and the header removed, and the raw 842 buffer(s) passed to the 842
+ * software decompression library.
+ *
+ * This does not fall back to software compression, however, since the caller
+ * of this function is specifically requesting hardware compression; if the
+ * hardware compression fails, the caller can fall back to software
+ * compression, and the raw 842 compressed buffer that the software compressor
+ * creates can be passed to this driver for hardware decompression; any
+ * buffer without our specific header magic is assumed to be a raw 842 buffer
+ * and passed directly to the hardware.  Note that the software compression
+ * library will produce a compressed buffer that is incompatible with the
+ * hardware decompressor if the original input buffer length is not a multiple
+ * of 8; if such a compressed buffer is passed to this driver for
+ * decompression, the hardware will reject it and this driver will then pass
+ * it over to the software library for decompression.

-/**
- * nx842_constraints
- *
- * This provides the driver's constraints.  Different nx842 implementations
- * may have varying requirements.  The constraints are:
- *   @alignment:	All buffers should be aligned to this
- *   @multiple:		All buffer lengths should be a multiple of this
- *   @minimum:		Buffer lengths must not be less than this amount
- *   @maximum:		Buffer lengths must not be more than this amount
- *
- * The constraints apply to all buffers and lengths, both input and output,
- * for both compression and decompression, except for the minimum which
- * only applies to compression input and decompression output; the
- * compressed data can be less than the minimum constraint.  It can be
- * assumed that compressed data will always adhere to the multiple
- * constraint.
- *
- * The driver may succeed even if these constraints are violated;
- * however the driver can return failure or suffer reduced performance
- * if any constraint is not met.
+/* The first 5 bits of this magic are 0x1f, which is an invalid 842 5-bit
+ * template (see lib/842/842.h), so this magic number will never appear at
+ * the start of a raw 842 compressed buffer.  That is important, as any buffer
+ * passed to us without this magic is assumed to be a raw 842 compressed
+ * buffer, and passed directly to the hardware to decompress.

+ *   @minimum:		Buffer lengths must not be less than this amount
+ *   @maximum:		Buffer lengths must not be more than this amount

+ * The constraints apply to all buffers and lengths, both input and output,
+ * for both compression and decompression, except for the minimum which

+ * PF<->VF Messaging
+ * The PF has an array of 32-bit PF2VF registers, one for each VF.  The
+ * PF can access all these registers; each VF can access only the one
+ * register associated with that particular VF.
+ *
+ * The register functionally is split into two parts:
+ * The bottom half is for PF->VF messages. In particular when the first
+ * bit of this register (bit 0) gets set an interrupt will be triggered
+ * in the respective VF.
+ * The top half is for VF->PF messages. In particular when the first bit
+ * of this half of register (bit 16) gets set an interrupt will be triggered
+ * in the PF.
+ *
+ * The remaining bits within this register are available to encode messages.
+ * and implement a collision control mechanism to prevent concurrent use of
+ * the PF2VF register by both the PF and VF.
