Replace the BSP_CONSOLE_MINOR BSP option for the Xilinx Zynq BSPs with the new
BSP option ZYNQ_UART_KERNEL_IO_BASE_ADDR. Move the kernel I/O support to a
shared file.
Make the initialization and polled functions independent of the Termios
context. This helps to implement the kernel I/O support without a dependency
on the Termios framework.
Move declarations of bsp_interrupt_get_affinity() and
bsp_interrupt_set_affinity() to <bsp/irq-generic.h>. Canonicalize the
<bsp/irq.h> includes.
Implement bsp_interrupt_get_affinity() and bsp_interrupt_set_affinity() only if
needed (usually RTEMS_SMP).
Provide stub implementations for i386 to fix build errors.
The parameters are unused due to API constraints. The functions are
used through function pointers. Alternative implementations may use the
parameters.
Update #4862.
Pass the parameter of the clock interrupt handler to
Clock_driver_support_at_tick() and Clock_driver_timecounter_tick(). This makes
it possible to use the interrupt handler argument in clock drivers.
Use the interrupt handler provided by Clock_driver_support_install_isr() to
avoid local delarations of Clock_isr().
Update #4862.
We observed a strange behavior of the 1Hz timer when running cFS on Zynq
RPU. After some investigation, we reduced the error to the truncation
issue. This patch fixes the issue.
When unmounting a JFFS2 filesystem, any outstanding write buffers must
be flushed to disk. In some circumstances, these write buffers are
instantiated by a garbage collection pass and as such no inode number is
associated with it. Due to the way that JFFS2 processes these garbage
collection passes, a write buffer without any associated inodes will not
be flushed unless it is forced with jffs2_flush_wbuf_pad().
When resetting the QSPI FIFOs, the driver was reading write-only bits of
a register for status information when it was actually in a different
register. This corrects the driver so that it reads the correct status
bits.
Add an opportunistic page cache to the xnandpsu driver since it does not
implement partial page reads and common filesystem access patterns
perform multiple reads from the same page. This has been seen to provide
a 10x speedup to read speeds and a 2x speedup on first initialization
when used with JFFS2.
This fixes a logic inversion that was preventing creation of a Bad Block
Table (BBT) from scratch on devices that lack one. This was discovered
during upstream integration testing. The BBT management layer in this
driver is not designed to be easily testable other than on real hardware.
This adds a test to very that remounting a completely used, but empty
NOR JFFS2 filesystem is possible. Previously, this triggered an edge
condition in the JFFS2 scan code that prevented remount of a correctly
formed and uncorrupted filesystem.
On JFFS2 file systems on NOR flash or dataflash that does not have spare
area for metadata and thus does not invoke delayed writes, it is
possible to put the file system into a state where all blocks have been
written to and all files have been deleted from the filesystem. There is
a bug in the JFFS2 file system scan routine that detects this situation
as a corrupted file system since the scan routine relies on "used" space
to discriminate a valid file system when there are blocks that need to
be erased. The correct fix would require a partial rewrite of the scan
routine, so instead this patch tracks the space marked as obsolete along
with space at the end of each block that is otherwise too small to
contain a JFFS2 node so that it can me compared with the dirty space.
Corrupted data (or otherwise non-JFFS2 blocks) will still cause this
check to fail as corrupted data isn't recognized as obsoleted (deleted)
nodes.
The RAM origin had an unnecessary alignment requirement and the RAM
lenght had a reference that couldn't possibly be used. This removes
those obsolete option specifiers.
Make sure there is no spurious empty line between the gcov info and the
*** END OF GCOV INFO BASE64 ***
line. This helps to recalculate the hash correctly at the consumer
side.
This adds a pthread that runs the test as well to increase test
coverage. The original test would have passed if all threads returned
the address of the Init task's errno since no additional threads or
tasks were checked.
Stacked mode doubles the number of sectors and device size while
parallel mode doubles the sector size and the device size. Make sure
that this is accounted for in the device size accessor.
