https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295103 --- Comment #6 from Benoit SANSONI <benoit.sansoni@gmail.com> --- 1. You are right I left this debug (device_printf) to checkout the viddid value in dmesg. In addition, the viddid value could be used also in the code to apply fix only for the ST33KTPM2X32CKE3. But I did not do it in the current code. So the viddid if the debug is removed, will not be used and could provoke a warning during build process. Currently, for sure it can be removed. 2. Oups, sorry for the coding style! Easy to change in this case. 3. Your proposal "/* Return device to ready state; required by ST33KTPM2X32CKE3. */" is correct. 4. FYI, I explained before in this thread, I applied this patch to the kernel of the FreeBSD 14.2. By reading this code review https://reviews.freebsd.org/D45069, it seems that TPM_WRITE_4 is equivalent to WR4, and TPM_WRITE_BARRIER is equivalent to the line "bus_barrier(sc->mem_res, TPM_STS, 4, BUS_SPACE_BARRIER_WRITE);" Let me know whether it answer to your question. Or I missed something. -- You are receiving this mail because: You are the assignee for the bug.home | help
