The running state is a subset of runnable state which means that running

OWL_CPUx_ADDR is the physical address of CPUx wakeup function.
OWL_CPUx_FLAG is a valid flag of OWL_CPUx_ADDR.
After CPUxs are wakeuped by SEV instruction, they will check their own
OWL_CPUx_FLAG register. If the register vlaue is 0x55aa, CPUx will jump to

When an IRQ arrives during PDMA transfer, pread() and pwrite() return
without waiting for the 53C80 registers to be ready and this ends up
messing up the chip state. This was observed with SONY CDU-55S which is
slow enough to disconnect during 4096-byte reads.

Limit PDMA send to 512 B to avoid data corruption on DTC3181E. The

faster IBM DORS-32160. It's not clear what causes this. Documentation

The polling loops in pread() and pwrite() can easily become infinite
loops and hang the machine.

From: Ondrej Zary
generic_NCR5380_dma_xfer_len() incorrectly uses cmd->transfersize
which causes rescan-scsi-bus and CD-ROM access to hang the system.
Use cmd->SCp.this_residual instead, like other NCR5380 drivers.

Ondrej, would you please test this new series?
Changed since v1:
- PDMA transfer residual is calculated earlier.
- End of DMA flag check is now polled (if there is any residual).
Changed since v2:
- Bail out of transfer loops when Gated IRQ gets asserted.
- Make udelay conditional on board type.
The word "read" may be used to mean "DMA read operation" or
"SCSI READ command", though a READ command implies writing to memory.

The existing tools/testing/selftests/sysctl/ tests include two test cases,
but these use existing production kernel sysctl interfaces. We want to
expand test coverage but we can't just be looking for random safe production
values to poke at, that's just insane!
Instead just dedicate a test driver
Add a few initial respective tests for an array:
o Echoing values separated by spaces works
o Echoing only first elements will set first elements
o Confirm PAGE_SIZE limit still applies even if an array is used

a test against UINT_MAX. Make sure UINT_MAX works, and UINT_MAX+1
will fail and that negative values are not accepted.

can also override through an environment variable.

This adds a generic script to let us more easily add more tests cases.
Since we really have only two types of tests cases just fold them into the
one file. Each test unit is now identified into its separate function:

TEST_ID x NUM_TEST

Check return value from call to platform_get_irq(),
so in case of failure print error message and propagate
the return value.

platform_get_irq() returns an error code, but the ac97c
driver ignores it and always returns -ENXIO. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error.
Print and propagate the return value of platform_get_irq

The warning(str_error_r(errno)) pattern can be replaced with a function,
do it.
And while at it use pr_warning(), we have way too many error reporting
facilities, time to drop some, starting with the one we got from the git
sources.
