* Remove rge driver from Broadcom XLRSean Bruno2015-09-041-2564/+0
| | | | | | | | | | | | | | | nlge(4) is supposed to deprecate rge(4) for Broadcom XLR when it was introduced 5 years ago. rge doesn't build on -CURRENT due to MII changes. All the XLR kernel confs use nlge. Let's get rid of the old driver for FreeBSD 11. We can use 10-STABLE or SVN to go back and look at the old driver if needed.

* CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than tenJung-uk Kim2015-05-221-2/+2
| | | | | | | | | | | | | years for head. However, it is continuously misused as the mpsafe argument for callout_init(9). Deprecate the flag and clean up callout_init() calls to make them more consistent.

* fix mips build breakage introduced in r216375: atomic_store_int doesn't existsAndriy Gapon2010-12-131-3/+1
| | | | | | | | | | | | | | | | 1) 32-bit assignment are expected to always be atomic. 2) Release/acquire memory barrier semantics doesn't seem to be needed here. So a simple assignment can be used. Remove unused port_set_counter() while here, it also used to mis-use atomic_set_int(). Reported by: jhb Pointyhat to: avg MFC after: 3 weeks Notes: svn path=/head/; revision=216408

* Update message ring handling code for XLR/XLSJayachandran C.2010-10-031-7/+10
| | | | | | | | | | | | | | - Wakeup multiple threads per core using message ring watermark interrupts. - Update message ring handler registration, use the real device station id for registering interrupts. - rge/nlge: update for the new message ring registration code. - rge/nlge: use 2 message ring stations for incoming packets, this will allow more messages to be queued. - nlge: comment fixes, remove unused variable - style and whitespace fixes Notes: svn path=/head/; revision=213377
* Network driver updates.Jayachandran C.2010-09-161-55/+11
| | | | | | | | | | | | | | | | | - Move RMI MIPS extension to atomic increment word (LDADDWU) to common header file sys/mips/rmi/rmi_mips_exts.h - Fix xlr_ldaddwu() for 64 bit, it is a 32 bit operation, use unsigned int* instead of unsigned long* argument - Provide dummy xlr_enable_kx/xlr_restore_kx for n32 and n64. - Provide xlr_paddr_ld() instead of xlr_paddr_lw(), so that the descriptor formats are same for 32 and 64 bit - update nlge and rge for the changes These changes are also needed by the security driver which will be added later.

* sys/mips/rmi/msgring.h - fixes and clean up.Jayachandran C.2010-09-131-2/+2
| | | | | | | | | | | | | | - Remove sync from msgrng_send, sync needs to be called just once before sending. - Fix retry logic - don't reload registers when retrying in message_send, also fix check for send pending fail. - remove unused message_send_block_fast() - merge message_receive_fast() to message_receive - style(9) fixes, and comments - rge and nlge updated for the sys/mips/rmi/msgring.h changes Notes: svn path=/head/; revision=212553

* Clean up fast message ring code for XLR.Jayachandran C.2010-09-081-41/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix message ring send path: - define msgrng_access_enable() which disables local interrupts and enables message ring access. Also define msgrng_restore() which restores interrupts - remove all other msgrng enable/disable macros, no need of critical_enter and other locking here. - message_send() fixup: re-read status until pending bit clears - message_send_retry() fixup: retry only few times with interrupts disabled - Fix up message_send/message_send_retry callers - call msgrng_access_enable() and msgrng_restore() correctly so that interrupts are not disabled for long. - removed unused and obsolete code from sys/mips/rmi/msgring.h - some style fixes - more later rge.c (XLR GMAC driver): - updated for the message ring changes - remove unused message_send_block() - retry on credit failure, this is not a permanent failure when credits are configured correctly. Add panic if credits are not available to send for a long time. Notes: svn path=/head/; revision=212321

However its possible that the algorithm detects when the second page is not used (when the data aligns perfectly to the bottom of the page). This caused a 0 len descriptor to be added which locks up the rge device. Skip such things with a continue. JC provided this patch...

* Merge from projects/mips to head by hand:Warner Losh2010-01-101-0/+2748
Copy sys/dev/rmi to sys/mips/rmi/dev [sic]. For devices that are on only one SoC, or family of SoC, we place them under sys/<vendor>/dev. I'll fix the build problems this causes as best I can since rmi kernel require external toolchains due to lack of support for rmi op-codes in the ancient binutils we have in the tree.
