Update the imx5/imx6 cpu_reset() implementation based on a new understanding
of the SRS (software reset) bit in the watchdog control register. Despite
what the manual seems to imply, this bit DOES trigger an immediate reset, as
opposed to simply flagging the type of reset as software-triggered.
Rename sysctl node hw.imx6 to hw.imx. Move its definition to imx_machdep.c
so that code shared between imx5 and imx6 can work with OIDs under that node.
Add last_reset_status (integer) and last_reset_reason (string) OIDs that
provide info about the last chip reset (power-on, software reset, watchdog
timeout).

Fix printf format to allow for bus_size_t not being u_long on all platforms.
Fix an alignment check that is wrong in half the busdma implementations.
This will enable the elimination of a workaround in the USB driver that
artifically allocates buffers twice as big as they need to be (which
actually saves memory for very small buffers on the buggy platforms).
When deciding how to allocate a dma buffer, armv4, armv6, mips, and
x86/iommu all correctly check for the tag alignment <= maxsize as enabling
simple uma/malloc based allocation. Powerpc, sparc64, x86/bounce, and
arm64/bounce were all checking for alignment < maxsize; on those platforms
when alignment was equal to the max size it would fall back to page-based
allocators even for very small buffers.
This change makes all platforms use the <= check. It should be noted that
on all platforms other than arm[v6] and mips, this check is relying on
undocumented behavior in malloc(9) that if you allocate a block of a given
size it will be aligned to the next larger power-of-2 boundary. There is
nothing in the malloc(9) man page that makes that explicit promise (but the
busdma code has been relying on this behavior all along so I guess it works).
Arm and mips code uses the allocator in kern/subr_busdma_buffalloc.c, which
does explicitly implement this promise about size and alignment. Other
platforms probably should switch to the aligned allocator.

Add FDT compatibility to the icee driver.
The FDT bindings for eeprom parts don't include any metadata about the
device other than the part name encoded in the compatible property.
Instead, a driver is required to have a compiled-in table of information
about the various parts (page size, device capacity, addressing scheme). So
much for FDT being an abstract description of hardware characteristics, huh?
In addition to the FDT-specific changes, this also switches to using the
newer iicbus_transfer_excl() mechanism which holds bus ownership for the
duration of the transfer. Previously this code held the bus across all
the transfers needed to complete the user's IO request, which could be
up to 128KB of data which might occupy the bus for 10-20 seconds. Now the
bus will be released and re-aquired between every page-sized (8-256 byte)
transfer, making this driver a much nicer citizen on the i2c bus.
The hint-based configuration mechanism is still in place for non-FDT systems.
|
|
|
|
|
|
|
| |
Add iicbus_transfer_excl(), a helper routine to do an i2c bus transaction
while holding exclusive ownership of the bus. This is the routine most
slave drivers should use unless they have a need to acquire and hold the
bus across a series of related operations that involves multiple transfers.

Fix parsing of I2C addresses properties in fdt data. I2C address is
represented in 7-bits format in DT files, but system expect it in 8-bit
format. Also, fix two drivers that locally hack around this bug.
This includes a direct-commit change to the beaglebone dts data in the
10-stable branch to adjust the i2c slave addresses directly. In -current
the equivelent change happened with a switch from homegrown to standard
fdt data.

bsdinstall: Suggest the GPT+Active workaround on Dell T5810
The Dell Precision Tower 5810 fails to boot from GPT in Legacy/BIOS mode
without the Active flag in the Protective MBR. Suggest the workaround
during installation.
Since an increasing number of Dell systems exhibit this behavior,
I imagine all Dells past a certain date will do so. I would like
to suggest the workaround for all Dells with a BIOS date of, say,
2014 or later, but I would need to test a variety of systems before
committing such a change.
Relnotes: We should probably suggest using GPT+Active on "recent" Dells.

Test for EPROTOTYPE not EPROTONOSUPPORT
- `SOCK_RAW` is the implied supported type parameter for socket(2) per route(4)
- localsw in `sys/kern/uipc_usrreq.c` doesn't have an entry for `SOCK_RAW`, so
the prototype is invalid (this isn't explicitly documented anywhere I could
find)

Make PPS ASSERT/CLEAR events match the RS-232 signal levels as per RFC 2783.
Previously the polarity was for TTL levels, which are the reverse of RS-232.
Also add handling of the UART_PPS_INVERT_PULSE option bit in the sysctl
value, the same as was recently added to uart(4), so that people using TTL
level connections can request a logical inverting of the signal.
Use the named constants from the new dev/uart/uart_ppstypes.h for the pps
capture modes and option bits.

Initialize vm_page_prot to VM_MEMATTR_DEFAULT instead of 0.
If a driver's Linux mmap callback passed vm_page_prot through unchanged,
then linux_dev_mmap_single() would try to apply whatever VM_MEMATTR_xxx
value 0 is to the mapping. On x86, VM_MEMATTR_DEFAULT is the PAT value
for write-back (WB) which is 6, while 0 maps to the PAT value for
uncacheable (UC). Thus, any mmap request that did not explicitly set
page_prot was tried to map memory as UC triggering the warning in
sg_pager_getpages().

286974:
Remove reference to non-existent kern_openat(9).
291653:
The cdevpriv_dtr_t typedef was not able to be used in a function prototype
like the various d_*_t typedefs since it declared a function pointer rather
than a function. Add a new d_priv_dtor_t typedef that declares the function
and can be used as a function prototype. The previous typedef wasn't
useful outside of the cdevpriv implementation, so retire it.
The name d_priv_dtor_t was chosen to be more consistent with cdev methods
since it is commonly used in place of d_close_t even though it is not a
direct pointer in struct cdevsw.

If vnets are torn down while ifconfig runs an ioctl to say, destroy an
epair(4), we may hit if_detach_internal() without holding a lock and by
the time we aquire it the interface might be gone.
We should not panic() in this case as it is our fault for not holding
the lock all the way. It is not ideal to return silently without error
to user space, but other callers will all ignore the return values so
do not change the entire KPI for little benefit for now.
The ifp will be dealt with one way or another still.

If bootverbose is enabled every vnet startup and virtual interface
creation will print extra lines on the console. We are generally not
interested in this (repeated) information for each VNET. Thus only
print it for the default VNET. Virtual interfaces on the base system
will remain printing information, but e.g. each loopback in each vnet
will no longer cause a "bpf attached" line.

If the bus is detached and deleted by a call to device_delete_child() or
device_delete_children() on a device higher in the tree, I²C children
were already detached and deleted. So the device_t pointer stored in sc
points to freed memory: we must not try to delete it again.
By using device_delete_children(), we let subr_bus.c figure out if there
are children to take care of.
While here, make sure iicbus_detach() and iicoc_detach() call
device_delete_children() too, to be safe.
