      bnx2x: Using the new FW · ca00392c
      由 Eilon Greenstein 提交于 
      The new FW improves the packets per second rate. It required a lot of change in
the FW which implies many changes in the driver to support it. It is now also
possible for the driver to use a separate MSI-X vector for Rx and Tx - this also
add some to the complicity of this change.

All things said - after this patch, practically all performance matrixes show
improvement.
Though Vladislav Zolotarov is not signed on this patch, he did most of the job
and deserves credit for that.

      bnx2x: Separated FW from the source. · 94a78b79
      由 Vladislav Zolotarov 提交于 
      >From now on FW will be downloaded from the binary file using request_firmware.

There will be different files for every supported chip. Currently 57710 (e1) and
57711 (e1h).

File names have the following format: bnx2x-<chip version>-<FW version>.fw.
ihex versions of current FW files are submitted in the next patch.

Each binary file has a header in the following format:


struct bnx2x_fw_file_section {
	__be32 len;
	__be32 offset;
}

struct bnx2x_fw_file_hdr {
	struct bnx2x_fw_file_section init_ops;
	struct bnx2x_fw_file_section init_ops_offsets;
	struct bnx2x_fw_file_section init_data;
	struct bnx2x_fw_file_section tsem_int_table_data;
	struct bnx2x_fw_file_section tsem_pram_data;
	struct bnx2x_fw_file_section usem_int_table_data;
	struct bnx2x_fw_file_section usem_pram_data;
	struct bnx2x_fw_file_section csem_int_table_data;
	struct bnx2x_fw_file_section csem_pram_data;
	struct bnx2x_fw_file_section xsem_int_table_data;
	struct bnx2x_fw_file_section xsem_pram_data;
	struct bnx2x_fw_file_section fw_version;
}

Each bnx2x_fw_file_section contains the length and the offset of the appropriate
section in the binary file. Values are stored in the big endian format.

Data types of arrays:

init_data            __be32
init_ops_offsets     __be16
XXsem_pram_data         u8
XXsem_int_table_data    u8
init_ops             struct raw_op {
                          u8   op;
			__be24 offset;
                        __be32 data;
		     }
fw_version              u8

>From now boundaries of a specific initialization stage are stored in
init_ops_offsets array instead of being defined by separate macroes. The index 
in init_ops_offsets is calculated by BLOCK_OPS_IDX macro:

#define BLOCK_OPS_IDX(block, stage, end) \
       (2*(((block)*STAGE_IDX_MAX) + (stage)) + (end))

Security:

In addition to sanity check of array boundaries bnx2x will check a FW version.
Additional checks might be added in the future.

      fix modules_install via NFS · 8b249b68
      由 Sam Ravnborg 提交于 
      Rafael reported:

I get the following error from 'make modules_install' on my test boxes:

  HOSTCC  firmware/ihex2fw
/home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system
compilation terminated.
make[3]: *** [firmware/ihex2fw] Error 1
make[2]: *** [_modinst_post] Error 2
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2

where the configuration is that the kernel is compiled on a build box
with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by
each test box (full path to this directory is the same on the build box and on
the test boxes).  Then, I cd into <destdir>, run 'make modules_install' and get
the error above.

The issue turns out to be that we when we install firmware pick
up the list of firmware blobs from firmware/Makefile.
And this triggers the Makefile rules to update ihex2fw.

There were two solutions for this issue:
1) Move the list of firmware blobs to a separate file
2) Avoid ihex2fw rebuild by moving it to scripts

As I seriously beleive that the list of firmware blobs should be
done in a fundamental different way solution 2) was selected.
