sys/dev: further adoption of SPDX licensing ID tags. 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.

Move some hardware-related items to the hardware-related header. Shift to using the same queueing strategy that the amr driver uses. Some simple tests indicate that we use about 2% of the CPU at around 500tps with the controller completely saturated with I/O.

* Selected command codes.

Update to the latest development version of the Mylex driver. Changes in this version include: - Support for version 2.x firmware (2.42 or later recommended). This means we are the only open-source driver supporting these adapters. This code has only been tested on a Digital KZPCA adapter in an Alpha system, but is believed to be correct. NOTE: EISA adapters are not yet supported. - Support the BIOS/Firmware initialisation handshake protocol. This allows the driver to bring the card up to operational state even if the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system). - A working command pasthrough interface. This allows a user-space configuration tool (under development) to issue arbitrary commands to the controller or to devices in the system.

Add features required for basic userland management utility: - implement user-initiated background drive rebuild - implement user-initiated background consistency check - log controller-initiated background rebuild/check operations Try to fix the elusive "invalid log operation" bug, and panic if we do hit this one in the hopes of getting better information. Tidy up diagnostic messages. Try to use disk_create/disk_destroy correctly. This isn't working properly yet, but it's not clear whose fault that is.

#define MLX_STATUS_WEDGED 0xdead /* controller not listening */
Major update to the Mylex DAC960 driver adding new hardware support and fixing some major bugs. - Add support for the v5 firmware interface, used by the DAC1164P (tested) and AcceleRAID 352 (untested but should work). We now cover all of the Mylex family's protocols except for v2 (used by EISA and Alpha-compatible cards). - Fix an accounting bug which resulted in endless 'poll still busy' messages. In situations of high controller load the count of poll commands could be incremented without actually successfully launching a command. This totally removes the accounting for status poll commnads; it was its own worst enemy. - Add some simple reentry prevention locks to processing of the waiting and completed command queues to prevent races which could result in I/O being done or completed twice (both are fatal). This highlights a need for simple locking primitives in both the UP and SMP kernels. - Streamline the handling of command completion to reduce the amount of redundant work being done. Remove the code which tests for commands that have gone missing in action; nobody has ever seen one of these and it wouldn't have worked properly anyhow. - Handle disconnection of drives from the controller in the detach, not shutdown method. This avoids problems flushing the cache in a panic when a drive is mounted. - Don't call bus_generic_detach when disconnecting drives; it doesn't actually do anything useful. - Increment the log message index regardless of whether we actually retrieved one or not. If we run into a message that we can't fetch, we don't want to spin endlessly complaining about the fact. - Don't assume that interrupts will work when we're flushing the controller. We may think they are enabled, but in eg. a panic situation the controller may not be able to deliver an interrupt.

Add support for the version 4 firmware interface and the DAC960 PG and PJ cards. This will probably also support the AcceleRAID and eXtremeRAID cards, but nobody has volunteered one for testing, so I haven't enabled their PCI device IDs. Slightly clean up communication between the disk devices and the controller device as per new practice, and move some more register- related items int mlxreg.h from mlxvar.h. Remove some unnecessary read-modify-write operations to the card control registers; they don't behave like that. Increase the status polling interval to 10 seconds. It's still possible to load the card up to the point where a status poll will find the previous poll still running, but this will reduce the incidence of complaints.

Add locking to mlx(4) to make it MPSAFE along with some other fixes: - Use callout(9) rather than timeout(9). - Add a mutex as an I/O lock that protects the adapter and is used for the I/O path. - Add an sx lock as a configuration lock that protects the relationship of configured volumes. - Freeze the request queue when a DMA load is deferred with EINPROGRESS and unfreeze the queue when the DMA callback is invoked. - Explicitly poll the hardware while waiting to submit a command to allow completed commands to free up slots in the command ring. - Remove driver-wide 'initted' variable from mlx_*_fw_handshake() routines. That state should be per-controller instead. Add it as an argument since the first caller knows when it is the first caller. - Remove explicit bus_space tag/handle and use bus_*() rather than bus_space_*(). - Move duplicated PCI device ID probing into a mlx_pci_match() routine. - Don't check for PCIM_CMD_MEMEN (the PCI bus will enable that when allocating the resource) and use pci_enable_busmaster() rather than manipulating the register directly. Tested by: no one despite multiple requests (hope it works)

#define MLX_V4_IDB_INIT_BUSY (1<<1) /* initialisation in progress */
Add support for the version 4 firmware interface and the DAC960 PG and PJ cards. This will probably also support the AcceleRAID and eXtremeRAID cards, but nobody has volunteered one for testing, so I haven't enabled their PCI device IDs. Slightly clean up communication between the disk devices and the controller device as per new practice, and move some more register- related items int mlxreg.h from mlxvar.h. Remove some unnecessary read-modify-write operations to the card control registers; they don't behave like that. Increase the status polling interval to 10 seconds. It's still possible to load the card up to the point where a status poll will find the previous poll still running, but this will reduce the incidence of complaints.

Update to the latest development version of the Mylex driver. Changes in this version include: - Support for version 2.x firmware (2.42 or later recommended). This means we are the only open-source driver supporting these adapters. This code has only been tested on a Digital KZPCA adapter in an Alpha system, but is believed to be correct. NOTE: EISA adapters are not yet supported. - Support the BIOS/Firmware initialisation handshake protocol. This allows the driver to bring the card up to operational state even if the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system). - A working command pasthrough interface. This allows a user-space configuration tool (under development) to issue arbitrary commands to the controller or to devices in the system.

#define MLX_V4_FWERROR_PEND (1<<2) /* firmware error pending */
Major update to the Mylex DAC960 driver adding new hardware support and fixing some major bugs. - Add support for the v5 firmware interface, used by the DAC1164P (tested) and AcceleRAID 352 (untested but should work). We now cover all of the Mylex family's protocols except for v2 (used by EISA and Alpha-compatible cards). - Fix an accounting bug which resulted in endless 'poll still busy' messages. In situations of high controller load the count of poll commands could be incremented without actually successfully launching a command. This totally removes the accounting for status poll commnads; it was its own worst enemy. - Add some simple reentry prevention locks to processing of the waiting and completed command queues to prevent races which could result in I/O being done or completed twice (both are fatal). This highlights a need for simple locking primitives in both the UP and SMP kernels. - Streamline the handling of command completion to reduce the amount of redundant work being done. Remove the code which tests for commands that have gone missing in action; nobody has ever seen one of these and it wouldn't have worked properly anyhow. - Handle disconnection of drives from the controller in the detach, not shutdown method. This avoids problems flushing the cache in a panic when a drive is mounted. - Don't call bus_generic_detach when disconnecting drives; it doesn't actually do anything useful. - Increment the log message index regardless of whether we actually retrieved one or not. If we run into a message that we can't fetch, we don't want to spin endlessly complaining about the fact. - Don't assume that interrupts will work when we're flushing the controller. We may think they are enabled, but in eg. a panic situation the controller may not be able to deliver an interrupt.

Add locking to mlx(4) to make it MPSAFE along with some other fixes: - Use callout(9) rather than timeout(9). - Add a mutex as an I/O lock that protects the adapter and is used for the I/O path. - Add an sx lock as a configuration lock that protects the relationship of configured volumes. - Freeze the request queue when a DMA load is deferred with EINPROGRESS and unfreeze the queue when the DMA callback is invoked. - Explicitly poll the hardware while waiting to submit a command to allow completed commands to free up slots in the command ring. - Remove driver-wide 'initted' variable from mlx_*_fw_handshake() routines. That state should be per-controller instead. Add it as an argument since the first caller knows when it is the first caller. - Remove explicit bus_space tag/handle and use bus_*() rather than bus_space_*(). - Move duplicated PCI device ID probing into a mlx_pci_match() routine. - Don't check for PCIM_CMD_MEMEN (the PCI bus will enable that when allocating the resource) and use pci_enable_busmaster() rather than manipulating the register directly. Tested by: no one despite multiple requests (hope it works)

Updates resulting from new documentation from Mylex and some cleaning: - Don't keep private copies of some of the data fields from the ENQUIRY and ENQUIRY2 commands. Instead, standardise on the ENQUIRY2 command for initial adapter information, and keep a copy of the entire structure. Refer to it where appropriate. - Move all of the controller description functionality into a new function. Print lots more controller data if bootverbose is set. Add knowledge of the DAC960 PR, PT, PTL0 and PRL controllers, rename the 960PTL -> PTL0 and 1100P -> 1100PVX. - Correctly terminate an error message.

Updates resulting from new documentation from Mylex and some cleaning: - Don't keep private copies of some of the data fields from the ENQUIRY and ENQUIRY2 commands. Instead, standardise on the ENQUIRY2 command for initial adapter information, and keep a copy of the entire structure. Refer to it where appropriate. - Move all of the controller description functionality into a new function. Print lots more controller data if bootverbose is set.

Update to the latest development version of the Mylex driver. Changes in this version include: - Support for version 2.x firmware (2.42 or later recommended). This means we are the only open-source driver supporting these adapters. This code has only been tested on a Digital KZPCA adapter in an Alpha system, but is believed to be correct. NOTE: EISA adapters are not yet supported. - Support the BIOS/Firmware initialisation handshake protocol. This allows the driver to bring the card up to operational state even if the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system). - A working command pasthrough interface. This allows a user-space configuration tool (under development) to issue arbitrary commands to the controller or to devices in the system.

Move some hardware-related items to the hardware-related header. Shift to using the same queueing strategy that the amr driver uses. Some simple tests indicate that we use about 2% of the CPU at around 500tps with the controller completely saturated with I/O.
