1.1	09-Apr-2018	christos	branches: 1.1.2; rename panel to button.
1.1.2.2	16-Apr-2018	pgoyette	Sync with HEAD, resolve some conflicts
1.1.2.1	09-Apr-2018	pgoyette	file button.c was added on branch pgoyette-compat on 2018-04-16 01:59:55 +0000
1.3	12-Feb-2009	rumble	Enable Personal IRIS 4D/20 and 4D/25 support: - Adapt int(4) to handle the INT1 chip - Move generic rtc clocks out of hpc/ and into dev/ - Handle the very strangely wired eeprom and other bits in arcemu - Sprinkle MACH_SGI_IP6 as necessary - Enable IP6/IP10 devices in GENERIC32_IP12. Yes, the naming is poor but there's no winning with kernel/hw compatibility on sgimips... Tested on my 4D/25. Doesn't (appear to) break macallan@'s IP22.

1.5	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.4	27-Sep-2002	thorpej	Rather than referencing the cfdriver directly in the cfdata entries, instead use a string naming the driver. The cfdriver is then looked up in a list which is built at run-time.
1.3	13-Mar-2002	simonb	Replace lots of 8x<space> with <tabs> and other miscellaneous indentation fixes. Wrap a couple of long lines. Use <return-type>\n<function name> as per KNF in a few places.

1.17	08-May-2019	isaki	Merge isaki-audio2 branch, the overhaul of audio subsystem. - Interrupt-oriented system rather than thread-oriented. - Improve stability, quality and performance. - Split playback and record cleanly. Improve halfduplex support. - Many bugs are fixed including deadlocks, resource leaks, abuses, etc. - Simplify audio filter mechanism. The encoding/channels/frequency conversions are completely handled in the upper layer. So the hard- ware driver only converts its hardware encoding (if necessary). - audio_hw_if changes: - Obsoletes query_encoding and add query_format instead. - Obsoletes set_params and add set_format instead. - Remove drain, setfd, mappage. - The call sequences are changed. - ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted. - ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced. - cleanup config attributes: au*conv and mulaw. - All hardware drivers should follow it (I've done as much as possible). Some file paths are changed: - dev/audio.c -> dev/audio/audio.c (rewritten) - dev/audiovar.h -> dev/audio/audiovar.h - dev/audio_dai.h -> dev/audio/audio_dai.h - dev/audio_if.h -> dev/audio/audio_if.h - dev/audiobell.c -> dev/audio/audiobell.c - dev/audiobellvar.h -> dev/audio/audiobellvar.h - dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c
1.16	09-Apr-2018	christos	branches: 1.16.2; 1.16.4; rename panel to button.
1.15	09-Apr-2018	christos	rename "panel" to "button" to avoid conflict with fdt
1.14	14-May-2009	macallan	branches: 1.14.62; add a driver for the Indy's front panel buttons. - power button presses are reported to sysmon - volume control buttons are reported to PMF TODO: add better key repeat code. The hardware keeps firing interrupts at us whenever a button is down and not on - say - status change. If we don't clear the interrupt we'll be fired on until someone clears it. We should probably disable the entire interrupt and occasionally poll for button release.
1.13	12-Feb-2009	rumble	Enable Personal IRIS 4D/20 and 4D/25 support: - Adapt int(4) to handle the INT1 chip - Move generic rtc clocks out of hpc/ and into dev/ - Handle the very strangely wired eeprom and other bits in arcemu - Sprinkle MACH_SGI_IP6 as necessary - Enable IP6/IP10 devices in GENERIC32_IP12. Yes, the naming is poor but there's no winning with kernel/hw compatibility on sgimips... Tested on my 4D/25. Doesn't (appear to) break macallan@'s IP22.
1.12	27-Aug-2006	bjh21	branches: 1.12.60; 1.12.68; 1.12.70; 1.12.74; 1.12.78; Remove obsolete "sbic" define.
1.11	26-Aug-2006	bjh21	Move the sgimips "sbic" driver from arch/sgimips/hpc/sbic.c to dev/ic/wd33c93.c. This may not be the best WD33C93 driver we've got, but it's the most recently worked on and probably the most portable, so it seems like a good basis for further work (and in particular an acorn26 driver for the Acorn SCSI card). There's no functional change in this commit, and sgimips kernels still compile.
1.10	28-Dec-2005	kurahone	branches: 1.10.4; 1.10.8; Added support for the IP22 IOC's parallel port (PI1). Code contributed by Joe Britt. Reviewed by <sekiya> and <kurahone>.
1.9	11-Dec-2005	christos	merge ktrace-lwp.
1.8	22-Nov-2003	sekiya	branches: 1.8.16; Add dpclock driver (and minimal hpc1 goo) for ip20.
1.7	17-Oct-2003	sekiya	Compile dsclock_hpc.c only if dsclock is present in config file.
1.6	27-Sep-2003	he	Allow kernels without the haltwo driver configured to build, i.e. make the driver optional by adding the haltwo attribute.
1.5	25-Sep-2003	lonewolf	Support for HAL2 audio controller attached to the HPC ASIC, found on SGI Indy. The driver is not too heavily tested and only supports audio playback and master volume setting currently.
1.4	13-Mar-2002	simonb	branches: 1.4.12; Replace lots of 8x<space> with <tabs> and other miscellaneous indentation fixes. Wrap a couple of long lines. Use <return-type>\n<function name> as per KNF in a few places.
1.3	25-Nov-2001	soren	Adjust for dsclock name change.
1.2	19-Aug-2001	wdk	branches: 1.2.6; Initial implementation of WD33C9x SCSI driver for SGI IP22 platforms. Based on mvme68k and Atari drivers for the same chipset with the addition of bus_space support. Attempts have been made to seperate out the machine dependent dma components and more work is required in this area. Tested on SGI R4K Indy, but has little testing on other platforms.
1.1	11-May-2001	thorpej	branches: 1.1.2; Autoconfiguration glue for HPC devices. From Rafal K. Boni.
1.1.2.3	16-Mar-2002	jdolecek	Catch up with -current.
1.1.2.2	10-Jan-2002	thorpej	Sync kqueue branch with -current.

1.24	16-Mar-2019	isaki	branches: 1.24.2; Use C99 style struct initializer to audio_hw_if.
1.23	01-Jun-2017	chs	branches: 1.23.10; remove checks for failure after memory allocation calls that cannot fail: kmem_alloc() with KM_SLEEP kmem_zalloc() with KM_SLEEP percpu_alloc() pserialize_create() psref_class_create() all of these paths include an assertion that the allocation has not failed, so callers should not assert that again.
1.22	24-Nov-2011	mrg	branches: 1.22.8; 1.22.26; put back IPL_AUDIO and splaudio(), at the request of rmind. they are aliases and now we can easily revert audio to IPL_VM if necessary, without having to revert the whole branch.
1.21	23-Nov-2011	jmcneill	Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From the original ad-audiomp branch notes: Add MP locking to the audio drivers. Making the audio drivers MP safe is necessary before efforts can be made to make the VM system MP safe. The are two locks per device instance, an ISR lock and a character device lock. The ISR lock replaces calls to splaudio()/splx(), and will be held across calls to device methods which were called at splaudio() before (e.g. trigger_output). The character device lock is held across calls to nearly all of the methods, excluding some only used for initialization, e.g. get_locks. Welcome to 5.99.57.
1.20	01-Jul-2011	dyoung	branches: 1.20.2; 1.20.4; #include <sys/bus.h> instead of <machine/bus.h>.
1.19	25-Jan-2011	tsutsui	Split device_t/softc. Tested on Indy.
1.18	25-Jan-2011	tsutsui	u_intNN_t -> uintNN_t
1.17	24-Sep-2009	tsutsui	branches: 1.17.4; 1.17.6; 1.17.8; Replace shutdownhook_establish(9) (which was added by me) with pmf_device_register1(9).
1.16	14-May-2009	macallan	set delta value for the mixer's master channel
1.15	24-Aug-2008	tsutsui	branches: 1.15.4; 1.15.12; Pacify haltwo audio on shutdown hook to avoid noise on poweroff.
1.14	17-Oct-2007	garbled	branches: 1.14.16; 1.14.20; 1.14.22; 1.14.26; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.13	23-Jul-2007	he	branches: 1.13.6; After move to 64-bit paddr_t, cast via vaddr_t before casting to void*. OK'ed by macallan@.
1.12	04-Mar-2007	christos	branches: 1.12.2; 1.12.10; 1.12.12; 1.12.14; Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.11	29-Dec-2006	rumble	branches: 1.11.2; IP12 (and perhaps other systems) appear to be buggy and incapable of reliably supporting badaddr(). False negatives appear to occur approximately 1.8 percent of the time, although neither false positives nor consecutive false negatives occur. We take advantage of the latter property and always use a wrapper that makes multiple checks. My IP12 no longer sees occasional ghost devices and related panics during boot.
1.10	04-Sep-2006	rumble	branches: 1.10.2; Check the haltwo hardware present bit in the match function, rather than in the attach function after we've thwacked several registers and potentially wedged the machine. This fixes booting on Challenge S systems and addresses PR 25202. Consequently, re-enable haltwo in the default kernel configuration. Many thanks to George Harvey for testing and feedback.
1.9	11-Dec-2005	christos	branches: 1.9.4; 1.9.8; 1.9.18; merge ktrace-lwp.
1.8	28-Feb-2005	sekiya	branches: 1.8.2; 1.8.4; Attempt to verify presence of haltwo hardware, rather than just blithely believing that all hpc3 have a haltwo. This should help Challenge-S owners.
1.7	15-Jan-2005	kent	branches: 1.7.2; 1.7.4; ansify and KNF
1.6	10-Jan-2005	kent	merge kent-audio1 branch, which introduces audio filter pipeline to the MI audio framework Summary of changes: * struct audio_params - remove sw_code, factor, factor_denom, hw_sample_rate, hw_encoding ,hw_precision, and hw_channels. Conversion information is conveyed by stream_filter_list_t. - change the type of sample_rate: u_long -> u_int - add `validbits,' which represents the valid data size in precision bits. It is required in order to distinguish 24/32bit from 24/24bit or 32/32bit. * audio_hw_if - add two parameters to set_params() stream_filter_list_t pfil, stream_filter_list rfil A HW driver should set filter recipes for requested formats - constify audio_params parameters of trigger_output() and trigger_input(). They represent audio formats for the hardware. - make open() and close() optional - add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters to round_blocksize() * sw_code is replaced with stream_filter_t. stream_filer_t converts audio data in an input buffer and writes into another output buffer unlike sw_code, which converts data in single buffer. converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c, dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are reimplemented as stream_filter_t * MI audio - audiosetinfo() builds filter pipelines from stream_filter_list_t filled by audio_hw_if::set_params() - audiosetinfo() returns with EINVAL if mmapped and set_params() requests filters - audio_write(), audio_pint(), and audio_rint() invoke a filter pipeline. - ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS, AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for AUDIO_GETINFO handle values for a buffer nearest to userland. * add `struct device ' parameter to ac97_attach() all of audio HW drivers follow audio_hw_if and ac97 changes
1.5	30-Dec-2004	rumble	Prepend HPC3 macros universally with "HPC3_" to distinctly recognise the corresponding revision and maintain consistency with HPC1. No functional change intended.
1.4	29-Oct-2004	yamt	branches: 1.4.2; constify audio_hw_if, midi_hw_if, and radio_hw_if.
1.3	29-Dec-2003	sekiya	branches: 1.3.4; Fixes to HPC abstraction layer from Steve Rumble: - hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are established in hpcreg.h. All references to these fields are updated with the exception of if_sq: (haltwo, hpcdma). This makes reading the code and spotting bugs easier. - hpcdma.c was applying EOCHAIN to the wrong descriptor word for the hpc1 case. - I added scsi_max_xfer to the abstraction layer, and it allows some crusty #defines in wdsc.c to be removed. hpc1 now doesn't waste descriptors as it once did. - hpcreg.h was updated to reflect the lack of XMITDONE bit in hpc1. HPC1_REV15 added for a test in hpc.c - hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and prints the output a little prettier ;) - power interrupts shouldn't establish on non-IP22 platforms.

1.8	23-Nov-2011	jmcneill	Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From the original ad-audiomp branch notes: Add MP locking to the audio drivers. Making the audio drivers MP safe is necessary before efforts can be made to make the VM system MP safe. The are two locks per device instance, an ISR lock and a character device lock. The ISR lock replaces calls to splaudio()/splx(), and will be held across calls to device methods which were called at splaudio() before (e.g. trigger_output). The character device lock is held across calls to nearly all of the methods, excluding some only used for initialization, e.g. get_locks. Welcome to 5.99.57.

1.73	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.72	24-Apr-2021	thorpej	branches: 1.72.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.71	15-Sep-2018	macallan	branches: 1.71.14; remove long unused power button handler

1.63	14-Dec-2009	matt	branches: 1.63.4; 1.63.6; 1.63.8; Merge from matt-nb5-mips64 Merge mips-specific arch files.
1.62	14-May-2009	macallan	add a driver for the Indy's front panel buttons. - power button presses are reported to sysmon - volume control buttons are reported to PMF TODO: add better key repeat code. The hardware keeps firing interrupts at us whenever a button is down and not on - say - status change. If we don't clear the interrupt we'll be fired on until someone clears it. We should probably disable the entire interrupt and occasionally poll for button release.
1.61	12-Feb-2009	rumble	Enable Personal IRIS 4D/20 and 4D/25 support: - Adapt int(4) to handle the INT1 chip - Move generic rtc clocks out of hpc/ and into dev/ - Handle the very strangely wired eeprom and other bits in arcemu - Sprinkle MACH_SGI_IP6 as necessary - Enable IP6/IP10 devices in GENERIC32_IP12. Yes, the naming is poor but there's no winning with kernel/hw compatibility on sgimips... Tested on my 4D/25. Doesn't (appear to) break macallan@'s IP22.
1.60	17-Oct-2007	garbled	branches: 1.60.20; 1.60.28; 1.60.30; 1.60.34; 1.60.38; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.59	23-Jul-2007	he	branches: 1.59.6; After move to 64-bit paddr_t, cast via vaddr_t before casting to void*. OK'ed by macallan@.
1.58	09-Jul-2007	ad	branches: 1.58.2; 1.58.4; Merge some of the less invasive changes from the vmlocking branch: - kthread, callout, devsw API changes - select()/poll() improvements - miscellaneous MT safety improvements
1.57	22-Feb-2007	rumble	branches: 1.57.4; 1.57.6; 1.57.12; Make this compile again.
1.56	21-Feb-2007	rumble	Disable handling of the power interrupt. We aren't handling it properly and hitting any of the buttons results in infinite such interrupts.
1.55	20-Feb-2007	rumble	Add a reasonably disgusting hack to not complain about a non-configured "sq" or "wdsc" device in the GIO32 SCSI and E++ adapter cases, respectively. This file is getting nasty, but we've just about covered all the bases now.
1.54	20-Feb-2007	rumble	Add wdsc devices for the GIO32 SCSI adapter.
1.53	20-Feb-2007	rumble	Only read the eeprom once per hpc.
1.52	19-Feb-2007	rumble	Support the sq(4) interface on the Challenge S's IOPLUS mezzanine. This requires us to configure the IOPLUS to use the appropriate DMA channel, depending on what other expansion cards may be installed. Further, we need to do a bit more configuration of the sq(4) DMA engine, which apparently was formerly being configured properly by the PROM. Use the same values, which appear to work fine. Also, extend the gio_arb_config interface as needed. NB: We're currently setting the IOPLUS board to long burst, but it may be better to use realtime. This will require some experimentation.
1.51	29-Dec-2006	rumble	branches: 1.51.2; Tweak comments.
1.50	29-Dec-2006	rumble	IP12 (and perhaps other systems) appear to be buggy and incapable of reliably supporting badaddr(). False negatives appear to occur approximately 1.8 percent of the time, although neither false positives nor consecutive false negatives occur. We take advantage of the latter property and always use a wrapper that makes multiple checks. My IP12 no longer sees occasional ghost devices and related panics during boot.
1.49	22-Dec-2006	rumble	Prefix 'dma_data{in,out}_cmd' with 'scsi_', since that's what they're used for. Also, remove the 'clk_freq' variable, since this value differs on a per-platform (IP12 is 20MHz, others are 10MHz) basis. NB: I have no idea what frequency the GIO SCSI cards use. We'll have to re-investigate this if we ever come across one.
1.48	22-Dec-2006	rumble	Remove errnoneous register definitions and rename some to be more specific. Also, remove unused/invalid fields in our hpc revision abstraction and be sure to zero entries when they do not apply to a specific revision.
1.47	22-Dec-2006	rumble	Use SGIMIPS_BUS_SPACE_HPC, rather than hard-coding it.
1.46	22-Dec-2006	rumble	Determine if we've an onboard HPC. If not, we must set up the bus arbiter appropriately. We may need to do further work to get the IOPLUS mezzanine devices working as well.
1.45	22-Dec-2006	rumble	Break our list of HPC devices into HPC1 and HPC3 variants. This cleans up the list a bit and avoids Challenge S from using the HPC1 offets for its HPC3-based secondary ethernet on the IOPLUS mezzanine board.
1.44	22-Dec-2006	rumble	Indigo and Indigo2 machines have only one shared interrupt for the two GIO slots. This differs from Indy, which has an interrupt per slot, neither of which is the same as on the other two machines. This lets my Phobos G160 run in both slots in my Indigo2 and my E++ adapter works in both slots in my Indigo.
1.43	22-Dec-2006	rumble	EEPROM and LED controls occupy the same byte. Unify them again.
1.42	22-Dec-2006	rumble	Provide attaching hpc devices with the eeprom contents, should a chip be connected to the HPC. The only real reason for doing this is to get the mac addresses off of E++ ethernet boards and the Challenge S IOPLUS board. If no eeprom is present, we read in invalid data and take some default action (query ARCBIOS).
1.41	22-Dec-2006	rumble	Sprinkle static.
1.40	22-Dec-2006	rumble	Rework detecting the HPC revision. In most cases we can presume what it is based on mach_type (or at least know the major revision). The only case we really need to concern ourselves with is differentiating between HPC1 and HPC3 on IP22. Specifically, between a HPC3 on the Challenge S IOPLUS board and a HPC1.5-based adapter in an Indy.
1.39	22-Dec-2006	rumble	Fix previous by including the necessary header.
1.38	22-Dec-2006	rumble	Remove superfluous extern declarations; they're already in the headers.

1.33	26-Aug-2005	drochner	s/locdesc_t/int/g
1.32	28-Jun-2005	drochner	branches: 1.32.2; convert remaining autoconf bus "submatch" functions to use the new signature (passing locators), and remove some which obviously don't serve any purpose (untested, sorry)
1.31	30-Dec-2004	rumble	Prepend HPC3 macros universally with "HPC3_" to distinctly recognise the corresponding revision and maintain consistency with HPC1. No functional change intended.
1.30	30-Dec-2004	rumble	Remove a few HPC1 register definitions for ones that don't exist. Also, HPC1_ENET_INTDELAYVAL isn't a magic number. It turns the interrupt delay off (by being the timer trigger bit), so name it more appropriately.
1.29	17-Aug-2004	rumble	Add some infrastructure to support HPC-based ethernet adapters (E++): o The static configuration table now identifies by HPC offset. o Added sq(4) entries for IP12, IP20, and IP24. o Accomodated HPC revision forcing based on kernel config flags.
1.28	11-Apr-2004	pooka	Make das blinkenlights, well, blink on IP12 also.
1.27	10-Apr-2004	pooka	* The HPC endianness register isn't mapped on my IP12, so don't try to unconditionally read it * IP12 glue from Steve Rumble
1.26	28-Feb-2004	sekiya	branches: 1.26.2; Blinkenlitzen for IP20 (Indigo).
1.25	02-Jan-2004	sekiya	IP20 has two z8530 chips -- one at 0xd00 for keyboard/mouse, one at 0xd10 for serial ports. Attach the former as zs1 to keep serial console goo as simple as possible.
1.24	30-Dec-2003	sekiya	Force little-endian mode on hpc1, and attach zs on IP20.
1.23	29-Dec-2003	sekiya	Fixes to HPC abstraction layer from Steve Rumble: - hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are established in hpcreg.h. All references to these fields are updated with the exception of if_sq: (haltwo, hpcdma). This makes reading the code and spotting bugs easier. - hpcdma.c was applying EOCHAIN to the wrong descriptor word for the hpc1 case. - I added scsi_max_xfer to the abstraction layer, and it allows some crusty #defines in wdsc.c to be removed. hpc1 now doesn't waste descriptors as it once did. - hpcreg.h was updated to reflect the lack of XMITDONE bit in hpc1. HPC1_REV15 added for a test in hpc.c - hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and prints the output a little prettier ;) - power interrupts shouldn't establish on non-IP22 platforms.
1.22	16-Dec-2003	sekiya	Introduce abstraction layer for HPC registers and values, which addresses the divergence between HPC revision 1.5 and revision 3. The wdsc driver has been updated to reflect this layer (and may now work on IP20). The sq driver needs a bit more work before it can be committed.
1.21	16-Dec-2003	sekiya	A slighly more descriptive iocreg.h now lives in ../ioc.
1.20	14-Dec-2003	sekiya	Allow hpc to attach on IP20.

1.4	20-Nov-2001	rafal	Fix up Jason's last cleanup (thanks for that, btw!!)... Don't attach hpc child devices that don't match our systype. Attempting to attach a wdsc1 on my Challenge S locks the box hard.
1.3	18-Nov-2001	thorpej	* Clean up HPC autoconfiguration a little. Pass device register and DMA register offsets, as well as IRQ, to children. Use direct config. Use machine type/subtype to determine which devices are present. * Add support for the second SCSI controller on the Indigo2.
1.2	19-Aug-2001	wdk	branches: 1.2.6; Initial implementation of WD33C9x SCSI driver for SGI IP22 platforms. Based on mvme68k and Atari drivers for the same chipset with the addition of bus_space support. Attempts have been made to seperate out the machine dependent dma components and more work is required in this area. Tested on SGI R4K Indy, but has little testing on other platforms.

The hardware keeps firing interrupts at us whenever a button is down and not on - say - status change. If we don't clear the interrupt we'll be fired on until someone clears it. We should probably disable the entire interrupt and occasionally poll for button release.

1.14	17-Oct-2007	garbled	branches: 1.14.20; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.9	29-Dec-2003	sekiya	Fixes to HPC abstraction layer from Steve Rumble: - hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are established in hpcreg.h. All references to these fields are updated with the exception of if_sq: (haltwo, hpcdma). This makes reading the code and spotting bugs easier. - hpcdma.c was applying EOCHAIN to the wrong descriptor word for the hpc1 case. - I added scsi_max_xfer to the abstraction layer, and it allows some crusty #defines in wdsc.c to be removed. hpc1 now doesn't waste descriptors as it once did. - hpcreg.h was updated to reflect the lack of XMITDONE bit in hpc1. HPC1_REV15 added for a test in hpc.c - hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and prints the output a little prettier ;) - power interrupts shouldn't establish on non-IP22 platforms.
1.8	16-Dec-2003	sekiya	Introduce abstraction layer for HPC registers and values, which addresses the divergence between HPC revision 1.5 and revision 3. The wdsc driver has been updated to reflect this layer (and may now work on IP20). The sq driver needs a bit more work before it can be committed.

(Identify message out phase is hardware assisted) - Improved timeout support (one per active control block) - Improved MESG_IN and MESG_OUT handling - Start to tidy up debugging output - Numerous bug fixes and cleanups throughout Changes are based largely on the NCR53c9x MI driver for ideas on how to DTRT.

1.19	19-Feb-2007	rumble	branches: 1.19.68; 1.19.74; 1.19.76; Support the sq(4) interface on the Challenge S's IOPLUS mezzanine. This requires us to configure the IOPLUS to use the appropriate DMA channel, depending on what other expansion cards may be installed. Further, we need to do a bit more configuration of the sq(4) DMA engine, which apparently was formerly being configured properly by the PROM. Use the same values, which appear to work fine. Also, extend the gio_arb_config interface as needed. NB: We're currently setting the IOPLUS board to long burst, but it may be better to use realtime. This will require some experimentation.
1.18	22-Dec-2006	rumble	branches: 1.18.2; Remove errnoneous register definitions and rename some to be more specific. Also, remove unused/invalid fields in our hpc revision abstraction and be sure to zero entries when they do not apply to a specific revision.
1.17	22-Dec-2006	rumble	EEPROM and LED controls occupy the same byte. Unify them again.
1.16	22-Dec-2006	rumble	Provide attaching hpc devices with the eeprom contents, should a chip be connected to the HPC. The only real reason for doing this is to get the mac addresses off of E++ ethernet boards and the Challenge S IOPLUS board. If no eeprom is present, we read in invalid data and take some default action (query ARCBIOS).
1.15	22-Dec-2006	rumble	Rework detecting the HPC revision. In most cases we can presume what it is based on mach_type (or at least know the major revision). The only case we really need to concern ourselves with is differentiating between HPC1 and HPC3 on IP22. Specifically, between a HPC3 on the Challenge S IOPLUS board and a HPC1.5-based adapter in an Indy.

1.12	30-Dec-2004	rumble	Remove a few HPC1 register definitions for ones that don't exist. Also, HPC1_ENET_INTDELAYVAL isn't a magic number. It turns the interrupt delay off (by being the timer trigger bit), so name it more appropriately.
1.11	17-Aug-2004	rumble	Add defines for the four possible HPC GIO bus addresses.

Also, remove the 'clk_freq' variable, since this value differs on a per-platform (IP12 is 20MHz, others are 10MHz) basis. NB: I have no idea what frequency the GIO SCSI cards use. We'll have to re-investigate this if we ever come across one.

1.7	29-Dec-2003	sekiya	branches: 1.7.16; Fixes to HPC abstraction layer from Steve Rumble: - hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are established in hpcreg.h. All references to these fields are updated with the exception of if_sq: (haltwo, hpcdma). This makes reading the code and spotting bugs easier. - hpcdma.c was applying EOCHAIN to the wrong descriptor word for the hpc1 case. - I added scsi_max_xfer to the abstraction layer, and it allows some crusty #defines in wdsc.c to be removed. hpc1 now doesn't waste descriptors as it once did. - hpcreg.h was updated to reflect the lack of XMITDONE bit in hpc1. HPC1_REV15 added for a test in hpc.c - hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and prints the output a little prettier ;) - power interrupts shouldn't establish on non-IP22 platforms.
1.6	16-Dec-2003	sekiya	Introduce abstraction layer for HPC registers and values, which addresses the divergence between HPC revision 1.5 and revision 3. The wdsc driver has been updated to reflect this layer (and may now work on IP20). The sq driver needs a bit more work before it can be committed.

They are counterpart of m_get_rcvif, which will come in another commit, hide internal of rcvif operation, and reduce the diff of the upcoming change. No functional change.
1.45	09-Feb-2016	ozaki-r	Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work.

1.43	02-Feb-2012	tls	branches: 1.43.6; 1.43.24; Entropy-pool implementation move and cleanup. 1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev. 2) Remove use of NRND as test for presence of entropy-pool code throughout source tree. 3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit. 4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources. 5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each. ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files).

This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

1.32	20-Feb-2007	rumble	Add a real probe so that we don't attach sq(4) on GIO32 SCSI adapters.
1.31	19-Feb-2007	rumble	Support the sq(4) interface on the Challenge S's IOPLUS mezzanine. This requires us to configure the IOPLUS to use the appropriate DMA channel, depending on what other expansion cards may be installed. Further, we need to do a bit more configuration of the sq(4) DMA engine, which apparently was formerly being configured properly by the PROM. Use the same values, which appear to work fine. Also, extend the gio_arb_config interface as needed. NB: We're currently setting the IOPLUS board to long burst, but it may be better to use realtime. This will require some experimentation.

1.27	31-Dec-2004	rumble	Do not report unexpected interrupts when not debugging. These seem to occur fairly often under normal operation with HPC1.5. Also, do not return if the interrupt is unexpected, but see if there is anything to handle regardless, which appears to always be the case with HPC1.5.
1.26	30-Dec-2004	rumble	Prepend HPC3 macros universally with "HPC3_" to distinctly recognise the corresponding revision and maintain consistency with HPC1. No functional change intended.
1.25	30-Dec-2004	rumble	Remove a few HPC1 register definitions for ones that don't exist. Also, HPC1_ENET_INTDELAYVAL isn't a magic number. It turns the interrupt delay off (by being the timer trigger bit), so name it more appropriately.
1.24	30-Dec-2004	rumble	Wrap seeq and hpc register reads and writes in macros for readability. While here, engage in some KNF and 80-column policing. No functional changes intended.
1.23	29-Dec-2004	rumble	Fix the HPC1 transmit logic, which was previously very broken. HPC1 does not mark transmitted descriptors like HPC3. We must query the HPC1 chip to determine what it expects the next descriptor to be, reclaim used ones, and restart if necessary. Each revision's corresponding logic now lives in its own sq_txring_hpc{1,3} function. HPC1's transmit interrupt conditions also differ from HPC3, so remove the INTR bits from descriptors when tagging new packets on to the end of the chain in order to avoid unwanted interrupts. Also, be extra careful when restarting the transmit ring. Since transmit interrupts seem to be relatively slow on HPC1, sq_start may be called while the DMA engine is quiescent, and before a transmit interrupt is asserted. We cannot behave like HPC3, which begins transmission from the first packet pulled from IFQ if the DMA engine is quiescent as this would skip enqueued packets. It appears that sq_start is never called before HPC3 asserts an interrupt, which restarts the transmit queue at the appropriate place. However, this often happens with HPC1 and we cannot assume that if DMA is inactive in sq_start, then all previously queued packets have fled the coop. XXX Is there a similar race possible with HPC3? HPC3 logic should remain functionally unchanged, and HPC1 should finally work properly.
1.22	29-Dec-2004	rumble	Remove the static sq_trace array and make it per-device as multiple seeq interfaces may exist. While here, add a few trace actions, move the related macros into sqvar.h, and enhance the sq_trace_dump output a bit.

Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.14	24-Apr-2021	thorpej	branches: 1.14.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.7	08-Mar-2002	thorpej	Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

(Identify message out phase is hardware assisted) - Improved timeout support (one per active control block) - Improved MESG_IN and MESG_OUT handling - Start to tidy up debugging output - Numerous bug fixes and cleanups throughout Changes are based largely on the NCR53c9x MI driver for ideas on how to DTRT.

Attempts have been made to seperate out the machine dependent dma components and more work is required in this area. Tested on SGI R4K Indy, but has little testing on other platforms.

1.14	02-Feb-2012	tls	branches: 1.14.6; 1.14.24; Entropy-pool implementation move and cleanup. 1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev. 2) Remove use of NRND as test for presence of entropy-pool code throughout source tree. 3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit. 4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources. 5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each. ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.
1.13	19-Nov-2011	tls	branches: 1.13.2; First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following: An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time. A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available. The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time. An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm. A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream. An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice. In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve. The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component. The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run. A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl. The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet. Manual pages for the new kernel interfaces are forthcoming.

1.7	29-Dec-2004	rumble	HPC1 seems to benefit from larger rings. This should be especially true on the transmit side, which appears to be significantly slower at interrupting than HPC3. XXX I used to be able to occasionally wedge the chip with SQ_NTXDESC == 32, but have not yet been able to reproduce that behaviour this evening with a larger value.
1.6	29-Dec-2004	rumble	Remove the static sq_trace array and make it per-device as multiple seeq interfaces may exist. While here, add a few trace actions, move the related macros into sqvar.h, and enhance the sq_trace_dump output a bit.

1.23	17-Oct-2007	garbled	branches: 1.23.20; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.19	20-Feb-2007	rumble	Add probe for wdsc so that we do not falsely attach wdsc(4) devices to E++ ethernet adapters. By resetting the chip we also allow the wd33c93 attach routines to succeed. Otherwise, device register accesses would result in a bus error.
1.18	22-Dec-2006	rumble	branches: 1.18.2; Prefix 'dma_data{in,out}_cmd' with 'scsi_', since that's what they're used for. Also, remove the 'clk_freq' variable, since this value differs on a per-platform (IP12 is 20MHz, others are 10MHz) basis. NB: I have no idea what frequency the GIO SCSI cards use. We'll have to re-investigate this if we ever come across one.
1.17	01-Oct-2006	bjh21	Allow wd33c93 attachments to choose what DMA mode it should use, and arrange to use burst mode on sec(4), which makes it slightly but significantly faster.
1.16	26-Aug-2006	bjh21	branches: 1.16.2; 1.16.4; Move the sgimips "sbic" driver from arch/sgimips/hpc/sbic.c to dev/ic/wd33c93.c. This may not be the best WD33C93 driver we've got, but it's the most recently worked on and probably the most portable, so it seems like a good basis for further work (and in particular an acorn26 driver for the Acorn SCSI card). There's no functional change in this commit, and sgimips kernels still compile.

1.13	29-Dec-2003	sekiya	Fixes to HPC abstraction layer from Steve Rumble: - hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are established in hpcreg.h. All references to these fields are updated with the exception of if_sq: (haltwo, hpcdma). This makes reading the code and spotting bugs easier. - hpcdma.c was applying EOCHAIN to the wrong descriptor word for the hpc1 case. - I added scsi_max_xfer to the abstraction layer, and it allows some crusty #defines in wdsc.c to be removed. hpc1 now doesn't waste descriptors as it once did. - hpcreg.h was updated to reflect the lack of XMITDONE bit in hpc1. HPC1_REV15 added for a test in hpc.c - hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and prints the output a little prettier ;) - power interrupts shouldn't establish on non-IP22 platforms.
1.12	16-Dec-2003	sekiya	Introduce abstraction layer for HPC registers and values, which addresses the divergence between HPC revision 1.5 and revision 3. The wdsc driver has been updated to reflect this layer (and may now work on IP20). The sq driver needs a bit more work before it can be committed.

1.3	18-Nov-2001	thorpej	* Add a callback to the front-end for the 33c93 driver to reset the controller/SCSI bus. * Implement controller/SCSI bus reset on SGI HPC3 SCSI using the "channel reset" bit in the SCSI DMA channel control register.
1.2	10-Nov-2001	wdk	branches: 1.2.2; Complete overhaul of WD33c93 SCSI driver - Full support for SCSI-2 Tagged commands (enabled by default) - Implement save and restore datapointer messages - Formalize interface between MI and MD drivers. - decouple interface between MD driver and DMA routines - Use scsipi layer where appropriate (Tags, Sync Negotiations etc) - control blocks stored using kernel pool(9) functions - evcnt(9) compliant counters - Enable advanced features on later WD33c93 chips. (Identify message out phase is hardware assisted) - Improved timeout support (one per active control block) - Improved MESG_IN and MESG_OUT handling - Start to tidy up debugging output - Numerous bug fixes and cleanups throughout Changes are based largely on the NCR53c9x MI driver for ideas on how to DTRT.
1.1	19-Aug-2001	wdk	branches: 1.1.2; 1.1.6; Initial implementation of WD33C9x SCSI driver for SGI IP22 platforms. Based on mvme68k and Atari drivers for the same chipset with the addition of bus_space support. Attempts have been made to seperate out the machine dependent dma components and more work is required in this area. Tested on SGI R4K Indy, but has little testing on other platforms.

1.34.10.1	10-Sep-2018	martin	Pull up following revision(s) (requested by tsutsui in ticket #1017): sys/arch/sgimips/conf/INSTALL32_IP2x: revision 1.10 sys/arch/sgimips/stand/boot/Makefile: revision 1.20 sys/arch/sgimips/sgimips/machdep.c: revision 1.146 sys/arch/sgimips/hpc/wdsc.c: revision 1.35 distrib/sgimips/instkernel/Makefile: revision 1.13 Disable misc options to shrink an INSTALL kernel for IP2x. The ARC BIOS on Indy seems to have ~8MB limit. Fixes PR port-sgimips/53378 from Naruaki Etomi. Should be pulled up to netbsd-7 and netbsd-8. - Fix build failure without options DDB and with pseudo-device ksyms. There is a typo for ksyms (NKSYMS vs NKSYM). Also use consistent "#if NKSYMS" rather than "#if NKSYMS > 0" etc. and add comments after corresponding #endif for readability. Fixes PR port-sgimips/53521 from Naruaki Etomi. Should be pulled up to (at least) netbsd-8. - Use elf2ecoff(1) rather than objcopy(1) to generat ecoff for old machines. objcopy(1) was used instead of elf2ecoff(1) since Makefile rev 1.9: http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/sgimips/stand/boot/Makefile#rev1.9 but it looks ELF binaries generated by recent binutils are too complicated to convert them to ecoff for old machines by objcopy(1). Reported by Naruaki Etomi in PR port-sgimips/53519. Should be pulled up to at least netbsd-8. - Fix wdsc(4) probe failure on HPC1.5 machines (Indigo R3k/R4k, IP6/IP10/IP12). The alignment adjustment code was removed in rev 1.36 for common mips bus_space changes, but the code was not bus_space related but used for uint32_t register acccess during probe. Reported and tested by Naruaki Etomi in PR port-sgimips/53522. Should be pulled up to netbsd-8. - Use elf2ecoff(1) rather than objcopy(1) to generate ecoff kernel. Reported by Naruaki Etomi in PR port-sgimips/53518. Should be pulled up to netbsd-7 and netbsd-8.
