Known Bugs for Libspe 2.0.0 20061107

The version “libspe 2.0.0 20061107” contained in the PS3 add-on package CD released with the launch of PS3 has the following known bugs: (Source codes of the version “1107” for libspe2 are contained in the source CD released with the add-on package CD. You can also obtain these codes from our mirror site.)

• The fourth argument “argp” and the fifth argument “envp” of spe_context_run() are not passed as arguments of a main function for SPE. (Patch)
• A segmentation fault occurs when the sixth argument “stopinfo” of spe_context_run() is set to null. (Patch)
• There is no definition of the constant “SPE_TAG_ALL, SPE_TAG_ANY, SPE_TAG_IMMEDIATE” to be specified as the third argument of “spe_mfcio_tag_status_read()” in a header file.
• There is no definition of the constant “SPE_SIG_NOTIFY_REG_1, SPE_SIG_NOTIFY_REG_2” to be specified as the second argument of “spe_signal_write()” in a header file.
• In spe_signal_write(), the error 'Bad file descriptor' occurs if data is written in the same register more than once.
• When “SPE_MAP_PS” is executed and the sequence from “context_create” to “spe_context_destroy()”is repeated, the second execution of “context_create” may be failed. (This is caused by a problem occurred in releasing resources when executing the destroy command.)
• Four arguments are used for “spe_out_mbox_read()” although three arguments are originally used (in manuals or in libspe2 - 2.0.1).

All the known bugs for libspe 2.0.0 mentioned here have been fixed in libspe 2.0.1.
