2020-10-13socket: don't clear SOCK_TSTAMP_NEW when SO_TIMESTAMPNS is disabledChristian Eggers
SOCK_TSTAMP_NEW (timespec64 instead of timespec) is also used for hardware time stamps (configured via SO_TIMESTAMPING_NEW). User space (ptp4l) first configures hardware time stamping via SO_TIMESTAMPING_NEW which sets SOCK_TSTAMP_NEW. In the next step, ptp4l disables SO_TIMESTAMPNS(_NEW) (software time stamps), but this must not switch hardware time stamps back to "32 bit mode". This problem happens on 32 bit platforms were the libc has already switched to struct timespec64 (from SO_TIMExxx_OLD to SO_TIMExxx_NEW socket options). ptp4l complains with "missing timestamp on transmitted peer delay request" because the wrong format is received (and discarded).

Willy Tarreau says: ==================== macb: support the 2-deep Tx queue on at91 while running some tests on my Breadbee board, I noticed poor network Tx performance. I had a look at the driver (macb, at91ether variant) and noticed that at91ether_start_xmit() immediately stops the queue after sending a frame and waits for the interrupt to restart the queue, causing a dead time after each packet is sent. The AT91RM9200 datasheet states that the controller supports two frames, one being sent and the other one being queued, so I performed minimal changes to support this. The transmit performance on my board has increased by 50% on medium-sized packets (HTTP traffic), and with large packets I can now reach line rate. Since this driver is shared by various platforms, I tried my best to isolate and limit the changes as much as possible and I think it's pretty reasonable as-is. I've run extensive tests and couldn't meet any unexpected situation (no stall, overflow nor lockup). There are 3 patches in this series. The first one adds the missing interrupt flag for RM9200 (TBRE, indicating the tx buffer is willing to take a new packet). The second one replaces the single skb with a 2-array and uses only index 0. It does no other change, this is just to prepare the code for the third one. The third one implements the queue. Packets are added at the tail of the queue, the queue is stopped at 2 packets and the interrupt releases 0, 1 or 2 depending on what the transmit status register reports. ==================== Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-10-13macb: support the two tx descriptors on at91rm9200Willy Tarreau
The at91rm9200 variant used by a few chips including the MSC313 supports two Tx descriptors (one frame being serialized and another one queued). However the driver only implemented a single one, which adds a dead time after each transfer to receive and process the interrupt and wake the queue up, preventing from reaching line rate. This patch implements a very basic 2-deep queue to address this limitation. The tests run on a Breadbee board equipped with an MSC313E show that at 1 GHz, HTTP traffic on medium-sized objects (45kB) was limited to exactly 50 Mbps before this patch, and jumped to 76 Mbps with this patch. And tests on a single TCP stream with an MTU of 576 jump from 10kpps to 15kpps. With 1500 byte packets it's now possible to reach line rate versus 75 Mbps before.

2020-10-13macb: prepare at91 to use a 2-frame TX queueWilly Tarreau
The RM9200 supports one frame being sent while another one is waiting in queue. This avoids the dead time that follows the emission of a frame and which prevents one from reaching line speed. Right now the driver supports only a single skb, so we'll first replace the rm9200-specific skb info with an array of two macb_tx_skb (already used by other drivers). This patch only moves the skb_length to txq[0].size and skb_physaddr to skb[0].mapping but doesn't perform any other change. It already uses [desc] in order to minimize future changes.

2020-10-13remoteproc: k3-r5: Add loading support for on-chip SRAM regionsSuman Anna
The K3 SoCs has various internal on-chip SRAM memories like the SRAM within the MCU domain or the shared MSMC RAM within NavSS that can be used for multiple purposes. One such purpose is to have the R5F cores use a portion of such on-chip SRAM for fast-access data or to directly execute code. Add support to the K3 R5 remoteproc driver to parse and support loading into such memories. The SRAM regions need to be mapped as normal non-cacheable memory to avoid kernel crashes when the remoteproc loader code uses the Arm64 memset library function (the "DC ZVA" instruction throws a alignment fault on device type memory). These SRAM regions are completely optional as not all firmware images require these memories, and any such memory has to be reserved as such in the DTS files.

2020-10-13remoteproc: k3-r5: Initialize TCM memories for ECCSuman Anna
The R5F processors on K3 SoCs all have two TCMs (ATCM and BTCM) that support 32-bit ECC. The TCMs are typically loaded with some boot-up code to initialize the R5 MPUs to further execute code out of DDR. The ECC for the TCMs is enabled by default on K3 SoCs due to internal default tie-off values, but the TCM memories are not initialized on device power up. Any read access without the corresponding TCM memory location initialized will generate an ECC error, and any such access from a A72 or A53 core will trigger a SError. So, zero initialize both the TCM memories before loading any firmware onto a R5F in remoteproc mode. Any R5F booted from U-Boot/SPL would require a similar initialization in the bootloader. Note that both the TCMs are initialized unconditionally as the TCM enable config bits only manage the access and visibility from R5.

2020-10-13remoteproc: k3-r5: Add a remoteproc driver for R5F subsystemSuman Anna
The TI K3 family of SoCs typically have one or more dual-core Arm Cortex R5F processor clusters/subsystems (R5FSS). This R5F subsystem/cluster can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. This subsystem has 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - TCMA and TCMB (further interleaved into two banks). The subsystem does not have an MMU, but has a Region Address Translater (RAT) module that is accessible only from the R5Fs for providing translations between 32-bit CPU addresses into larger system bus addresses. Add a remoteproc driver to support this subsystem to be able to load and boot the R5F cores primarily in LockStep mode. The code also includes the base support for Split mode. Error Recovery and Power Management features are not currently supported. Loading support includes the internal TCMs and DDR. RAT support is left for a future patch, and as such the reserved memory carveout regions are all expected to be using memory regions within the first 2 GB. The R5F remote processors do not have an MMU, and so require fixed memory carveout regions matching the firmware image addresses. Support for this is provided by mandating multiple memory regions to be attached to the remoteproc device. The first memory region will be used to serve as the DMA pool for all dynamic allocations like the vrings and vring buffers. The remaining memory regions are mapped into the kernel at device probe time, and are used to provide address translations for firmware image segments without the need for any RSC_CARVEOUT entries. Any firmware image using memory outside of the supplied reserved memory carveout regions will be errored out. The R5F processors on TI K3 SoCs require a specific sequence for booting and shutting down the processors. This sequence is also dependent on the mode (LockStep or Split) the R5F cluster is configured for. The R5F cores have a Memory Protection Unit (MPU) that has a default configuration that does not allow the cores to run out of DDR out of reset. This is resolved by using the TCMs for boot-strapping code that applies the appropriate executable permissions on desired DDR memory. The loading into the TCMs requires that the resets be released first with the cores in halted state. The Power Sleep Controller (PSC) module on K3 SoCs requires that the cores be in WFI/WFE states with no active bus transactions before the cores can be put back into reset. Support for this is provided by using the newly introduced .prepare() and .unprepare() ops in the remoteproc core. The .prepare() ops is invoked before any loading, and the .unprepare() ops is invoked after the remoteproc resource cleanup. The R5F core resets are deasserted in .prepare() and asserted in .unprepare(), and the cores themselves are started and halted in .start() and .stop() ops. This ensures symmetric usage and allows the R5F cores state machine to be maintained properly between using the sysfs 'state' variable, bind/unbind and regular module load/unload flows. The subsystem is represented as a single remoteproc in LockStep mode, and as two remoteprocs in Split mode. The driver uses various TI-SCI interfaces to talk to the System Controller (DMSC) for managing configuration, power and reset management of these cores. IPC between the A53 cores and the R5 cores is supported through the virtio rpmsg stack using shared memory and OMAP Mailboxes. The AM65x SoCs typically have a single R5FSS in the MCU voltage domain. The J721E SoCs uses a slightly revised IP and typically have three R5FSSs, with one cluster present within the MCU voltage domain (MCU_R5FSS0), and the remaining two clusters present in the MAIN voltage domain (MAIN_R5FSS0 and MAIN_R5FSS1). The integration of these clusters on J721E SoC is also slightly different in that these IPs do support an actual local reset line, while they are a no-op on AM65x SoCs.

The Texas Instruments K3 family of SoCs have one or more dual-core Arm Cortex R5F processor subsystems/clusters (R5FSS). The clusters can be split between multiple voltage domains as well. Add the device tree bindings document for these R5F subsystem devices. These R5F processors do not have an MMU, and so require fixed memory carveout regions matching the firmware image addresses. The nodes require more than one memory region, with the first memory region used for DMA allocations at runtime. The remaining memory regions are reserved and are used for the loading and running of the R5F remote processors. The R5F processors can also optionally use any internal on-chip SRAM memories either for executing code or using it as fast-access data. The added example illustrates the DT nodes for the single R5FSS device present on K3 AM65x family of SoCs.

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux Pull printk updates from Petr Mladek: "The big new thing is the fully lockless ringbuffer implementation, including the support for continuous lines. It will allow to store and read messages in any situation wihtout the risk of deadlocks and without the need of temporary per-CPU buffers. The access is still serialized by logbuf_lock. It synchronizes few more operations, for example, temporary buffer for formatting the message, syslog and kmsg_dump operations. The lock removal is being discussed and should be ready for the next release. The continuous lines are handled exactly the same way as before to avoid regressions in user space. It means that they are appended to the last message when the caller is the same. Only the last message can be extended. The data ring includes plain text of the messages. Except for an integer at the beginning of each message that points back to the descriptor ring with other metadata. The dictionary has to stay. journalctl uses it to filter the log. It allows to show messages related to a given device. The dictionary values are stored in the descriptor ring with the other metadata. This is the first part of the printk rework as discussed at Plumbers 2019, see https://lore.kernel.org/r/87k1acz5rx.fsf@linutronix.de. The next big step will be handling consoles by kthreads during the normal system operation. It will require special handling of situations when the kthreads could not get scheduled, for example, early boot, suspend, panic. Other changes: - Add John Ogness as a reviewer for printk subsystem. He is author of the rework and is familiar with the code and history. - Fix locking in serial8250_do_startup() to prevent lockdep report. - Few code cleanups" * tag 'printk-for-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: (27 commits) printk: Use fallthrough pseudo-keyword printk: reduce setup_text_buf size to LOG_LINE_MAX printk: avoid and/or handle record truncation printk: remove dict ring printk: move dictionary keys to dev_printk_info printk: move printk_info into separate array printk: reimplement log_cont using record extension printk: ringbuffer: add finalization/extension support printk: ringbuffer: change representation of states printk: ringbuffer: clear initial reserved fields printk: ringbuffer: add BLK_DATALESS() macro printk: ringbuffer: relocate get_data() printk: ringbuffer: avoid memcpy() on state_var printk: ringbuffer: fix setting state in desc_read() kernel.h: Move oops_in_progress to printk.h scripts/gdb: update for lockless printk ringbuffer scripts/gdb: add utils.read_ulong() docs: vmcoreinfo: add lockless printk ringbuffer vmcoreinfo printk: reduce LOG_BUF_SHIFT range for H8300 printk: ringbuffer: support dataless records ...

2020-10-13perf python: Autodetect python3 binaryJames Clark
Some distros don't come with python2 and only have python3 available. This causes the "'import perf' in python" self test to fail. This change adds python3 to the list of possible python versions that are autodetected but maintains the priorities for 'python2' and 'python' detection. Python3 has the lowest priority. Committer notes: On a fedora system without python2 packages the 'perf test python' continues to work: # python2 bash: python2: command not found... Similar command is: 'python' # rpm -qa | grep python2 # That "Similar command" gives the clue: # rpm -qf /usr/bin/python python-unversioned-command-3.8.5-5.fc32.noarch # rpm -ql python-unversioned-command /usr/bin/python /usr/share/man/man1/python.1.gz # With it in place the 'python' binary is found and perf builds the python binding using python3: # perf test -v python 19: 'import perf' in python : --- start --- test child forked, pid 379988 python usage test: "echo "import sys ; sys.path.append('/tmp/build/perf/python'); import perf" | '/usr/bin/python' " test child finished with 0 ---- end ---- 'import perf' in python: Ok # Looking at that path: # ls -la /tmp/build/perf/python total 1864 drwxrwxr-x. 2 acme acme 60 Oct 13 16:20 . drwxrwxr-x. 18 acme acme 4420 Oct 13 16:28 .. -rwxrwxr-x. 1 acme acme 1907216 Oct 13 16:28 perf.cpython-38-x86_64-linux-gnu.so # And: # ldd ~/bin/perf | grep python libpython3.8.so.1.0 => /lib64/libpython3.8.so.1.0 (0x00007f5471187000) # As soon as we remove it: # rpm -e python-unversioned-command-3.8.5-5.fc32.noarch # hash -r # python bash: python: command not found...

2020-10-13dt: Remove booting-without-of.rstRob Herring
booting-without-of.rst is an ancient document that first outlined Flattened DeviceTree on PowerPC initially. The DT world has evolved a lot in the 15 years since and booting-without-of.rst is pretty stale. The name of the document itself is confusing if you don't understand the evolution from real 'OpenFirmware'. Most of what booting-without-of.rst contains is now in the DT specification (which evolved out of the ePAPR). The few things that weren't documented in the DT specification are now. All that remains is the boot entry details, so let's move these to arch specific documents. The exception is arm which already has the same details documented.
