Oded writes:
This tag contains many changes for kernel 5.2.
The major changes are:
- Add a new IOCTL for debug, profiling and trace operations on the device.
This will allow the user to perform profiling and debugging of the
deep learning topologies that are executing on the ASIC.
- Add a shadow table for the ASIC's MMU page tables to avoid doing page
table walks on the device's DRAM during map/unmap operations.
- re-factor of ASIC-dependent code to be common code for all ASICs
In addition, there are many small fixes and changes. The notable ones are:
- Allow accessing the DRAM using virtual address through the debugFS
interface. Until now, only physical addresses were valid, but that is
useless for debugging when working with MMU.
- Allow the user to modify the TPC clock relaxation value to better
control TPC power consumption during topology execution.
- Allow the user to inquire about the device's status
(operational/Malfunction/in-reset) in the INFO IOCTL.
- Improvements to the device's removal function, to prevent crash in case
of force removal by the OS.
- Prevent PTE read/write during hard-reset. This will improve stability of
the device during hard-reset.

During hard-reset, contexts are closed as part of the tear-down process.
After a context is closed, the driver cleans up the page tables of that
context in the device's DRAM. This action is both dangerous and
unnecessary.
It is unnecessary, because the device is going through a hard-reset, which
means the device's DRAM contents are no longer valid and the device's MMU
is being reset.
It is dangerous, because if the hard-reset came as a result of a PCI
freeze, this action may cause the entire host machine to hang.
Therefore, prevent all device PTE updates when a hard-reset operation is
pending.

This patch makes some improvement in how IOCTLs behave when the device is
disabled or under reset.
The new code checks, at the start of every IOCTL, if the device is
disabled or in reset. If so, it prints an appropriate kernel message and
returns -EBUSY to user-space.
In addition, the code modifies the location of where the
hard_reset_pending flag is being set or cleared:
1. It is now cleared immediately after the reset *tear-down* flow is
finished but before the re-initialization flow begins.
2. It is being set in the remove function of the device, to make the
behavior the same with the hard-reset flow
There are two exceptions to the disable or in reset check:
1. The HL_INFO_DEVICE_STATUS opcode in the INFO IOCTL. This opcode allows
the user to inquire about the status of the device, whether it is
operational, in reset or malfunction (disabled). If the driver will
block this IOCTL, the user won't be able to retrieve the status in
case of malfunction or in reset.
2. The WAIT_FOR_CS IOCTL. This IOCTL allows the user to inquire about the
status of a CS. We want to allow the user to continue to do so, even if
we started a soft-reset process because it will allow the user to get
the correct error code for each CS he submitted.

This patch fixes a bug in the implementation of the function that removes
the device.
The bug can happen when the device is removed but not the driver itself
(e.g. remove by the OS due to PCI freeze in Power architecture).
In that case, there maybe open users that are calling IOCTLs while the
device is removed. This is a possible race condition that the driver must
handle. Otherwise, a kernel panic may occur.
This race is prevented in the hard-reset flow, because the driver makes
sure the users are closed before continuing with the hard-reset. This
race can not occur when the driver itself is removed because the OS makes
sure all the file descriptors are closed.
The fix is to make sure the open users close their file descriptors and if
they don't (after a certain amount of time), the driver sends them a
SIGKILL, because the remove of the device can't be stopped.
The patch re-uses the same code that is called from the hard-reset flow.

To make the memory ioctl code more readable, this patch moves the
legacy/debug code path of mmu-disabled to a separate function, which is
called (if necessary) from the main memory ioctl function.

This patch removes the enum value of ASIC_AUTO_DETECT because we can use
the validity of the pdev variable to know whether we have a real device or
a simulator. For a real device, we detect the asic type from the device ID
while for a simulator, the simulator code calls create_hdev() with the
specified ASIC type.
Set ASIC_INVALID as the first option in the enum to make sure that no
other enum value will receive the value 0 (which indicates a non-existing
entry in the simulator array).

This patch adds the ASIC-specific function for GOYA to configure the
coresight components.
Most of the components have an enabled/disabled flag, depending on whether
the user wants to enable the component or disable it.
For some of the components, such as ETR and SPMU, the user can also
request to read values from them. Those values are needed for the user to
parse the trace data.
The ETR configuration is also checked for security purposes, to make sure
the trace data is written to the device's DRAM.

Habanalabs ASICs use the ARM coresight infrastructure to support debug,
tracing and profiling of neural networks topologies.
Because the coresight is configured using register writes and reads, and
some of the registers hold sensitive information (e.g. the address in
the device's DRAM where the trace data is written to), the user must go
through the kernel driver to configure this mechanism.
This patch implements the common code of the IOCTL and calls the
ASIC-specific function for the actual H/W configuration.
The IOCTL supports configuration of seven coresight components:
ETR, ETF, STM, FUNNEL, BMON, SPMU and TIMESTAMP
The user specifies which component he wishes to configure and provides a
pointer to a structure (located in its process space) that contains the
relevant configuration.
The common code copies the relevant data from the user-space to kernel
space and then calls the ASIC-specific function to do the H/W
configuration.
After the configuration is done, which is usually composed
of several IOCTL calls depending on what the user wanted to trace, the
user can start executing the topology. The trace data will be written to
the user's area in the device's DRAM.
After the tracing operation is complete, and user will call the IOCTL
again to disable the tracing operation. The user also need to read
values from registers for some of the components (e.g. the size of the
trace data in the device's DRAM). In that case, the user will provide a
pointer to an "output" structure in user-space, which the IOCTL code will
fill according the to selected component.

If userspace doesn't end the input with a newline (which can easily

eth12
# printf 'eth3' > device_name
# cat device_name
eth32
I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.

Here are some binder, habanalabs, and vboxguest driver fixes for
5.1-rc3.
The Binder fixes resolve some reported issues found by testing, first by
the selinux developers, and then earlier today by syzbot.
The habanalabs fixes are all minor, resolving a number of tiny things.
The vboxguest patches are a bit larger. They resolve the fact that
virtual box decided to change their api in their latest release in a way
that broke the existing kernel code, despite saying that they were never
going to do that. So this is a bit of a "new feature", but is good to
get merged so that 5.1 will work with the latest release. The changes
are not large and of course virtual box "swears" they will not break
this again, but no one is holding their breath here.

The important fixes at this time are a couple fixes in ALSA core:
a fix for PCM is about the OOB access in PCM OSS plugins that has
been for long time, but hasn't hit so often until now just because
we allocated a large buffer via vmalloc(), and surfaced more often
after switching to kvmalloc(). Another fix is for a long-standing
PCM problem wrt racy PM resume. Others are trivial nospec coverage
and usual HD-audio quirks.

Merge tag 'sound-5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"The important fixes at this time are a couple fixes in ALSA core: a
fix for PCM is about the OOB access in PCM OSS plugins that has been
for long time, but hasn't hit so often until now just because we
allocated a large buffer via vmalloc(), and surfaced more often after
switching to kvmalloc(). Another fix is for a long-standing PCM
problem wrt racy PM resume.
Others are trivial nospec coverage and usual HD-audio quirks"
