| | | | | | | | | | | BIO_READ and BIO_WRITE, we've handled this expanded syntax poorly in drivers when the driver doesn't support a particular command. Do a sweep and fix that. Reported by: imp Notes: svn path=/head/; revision=357647
* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

* - Explicitly call twe_done() to poll the hardware when looping inJohn Baldwin2012-09-051-16/+19
| | | | | | | | | | | | | | | | | twe_start() to simulate the behavior on 4.x where the driver dropped spl to allow interrupts to run to free up space in the command queue. Be careful to only poll if we are going to make at least one more attempt to queue the current command. Also, when polling, be careful to not call twe_startio() to queue more commands to avoid recursion. - Move the buffer for formatting AEN messages into the softc instead of using a single driver-wide static buffer.

* Add locking to the twe(4) driver and make it MPSAFE:John Baldwin2012-08-131-57/+103
| | | | | | | | | | | | | | | | | | | | | | - Add per-controller configuration (sx) and I/O (mutex) locks. The configuration lock protects the relationship of volumes and drives while the I/O lock protects access to the controller's registers and the main I/O path. - Remove some checks for M_WAITOK malloc()'s failing. - Remove the explicit bus space tag/handle from the softc and use bus_*() rather than bus_space_*(). - Reuse the existing new-bus sysctl context instead of creating a new one. - Remove compat shims for FreeBSD 4.x. - Use pci_enable_busmaster() rather than doing it by hand, and rely on bus_alloc_resource() to enable PCI I/O decoding.

* Make the newbus subsystem Giant free by adding the new newbus sxlock.Attilio Rao2009-08-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.

| | | | | | | | | | | | | | | | | | | | | | | | issues which they found and asked to be changed so 3ware can offcially support the driver. Summary of the most significant changes: - TWE_OVERRIDE is no longer supported - If twe_getparam failed, bogus data would be returned to the caller - Cache the device unit in the twe_drive structure to aid debugging - Add the 3ware driver version. - Proper return error codes for many functions. - Track the minimum queue length statistics - 4.x compat: use the cached unit number from the twe_drive structure instead of the the cached si_drv2. 3ware found that after many loads and unloads that si_drv2 became corrupted. This did not happen in -current. Submitted by: Vinod Kashyap (with modifications by me) Approved by: re (rwatson) Notes: svn path=/head/; revision=123103

* Major update to the 'twe' driver.Mike Smith2000-10-251-1003/+844
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Layout reorganisation to enhance portability. The driver now has a relatively MI 'core' and a FreeBSD-specific layer over the top. Since the NetBSD people have already done their own port, this is largely just to help me with the BSD/OS port. - Request ID allocation changed to improve performance (I'd been considering switching to this approach after having failed to come up with a better way to dynamically allocate request IDs, and seeing Andy Doran use it in the NetBSD port of the driver convinced me that I was wasting my time doing it any other way). Now we just allocate all the requests up front. - Maximum request count bumped back to 255 after characterisation of a firmware issue (off-by-one causing it to crash with 256 outstanding commands). - Control interface implemented. This allows 3ware's '3dm' utility to talk to the controller. 3dm will be available from 3ware shortly. - Controller soft-reset feature added; if the controller signals a firmware or protocol error, the controller will be reset and all outstanding commands will be retried.
