Current code assumes PAGE_SIZE (the guest page size) is equal to the page size used to communicate with Hyper-V (which is always 4K). While this assumption is true on x86, it may not be true for Hyper-V on other architectures. For example, Linux on ARM64 may have PAGE_SIZE of 16K or 64K. A new symbol, HV_HYP_PAGE_SIZE, has been previously introduced to use when the Hyper-V page size is intended instead of the guest page size. Make this code work on non-x86 architectures by using the new HV_HYP_PAGE_SIZE symbol instead of PAGE_SIZE, where appropriate. Also replace the now redundant PAGE_SIZE_4K with HV_HYP_PAGE_SIZE. The change has no effect on x86, but lays the groundwork to run on ARM64 and others. Signed-off-by:

This reworks the SPI transfer implementation to make use of more of the SPI core features. The main benefit is to avoid the memcpy in sja1105_xfer_buf(). The memcpy was only needed because the function was transferring a single buffer at a time. So it needed to copy the caller-provided buffer at buf + 4, to store the SPI message header in the "headroom" area. But the SPI core supports scatter-gather messages, comprised of multiple transfers. We can actually use those to break apart every SPI message into 2 transfers: one for the header and one for the actual payload. To keep the behavior the same regarding the chip select signal, it is necessary to tell the SPI core to de-assert the chip select after each chunk. This was not needed before, because each spi_message contained only 1 single transfer. The meaning of the per-transfer cs_change=1 is: - If the transfer is the last one of the message, keep CS asserted - Otherwise, deassert CS We need to deassert CS in the "otherwise" case, which was implicit before. Avoiding the memcpy creates yet another opportunity. The device can't process more than 256 bytes of SPI payload at a time, so the sja1105_xfer_long_buf() function used to exist, to split the larger caller buffer into chunks. But these chunks couldn't be used as scatter/gather buffers for spi_message until now, because of that memcpy (we would have needed more memory for each chunk). So we can now remove the sja1105_xfer_long_buf() function and have a single implementation for long and short buffers. Another benefit is lower usage of stack memory. Previously we had to store 2 SPI buffers for each chunk. Due to the elimination of the memcpy, we can now send pointers to the actual chunks from the caller-supplied buffer to the SPI core. Since the patch merges two functions into a rewritten implementation, the function prototype was also changed, mainly for cosmetic consistency with the structures used within it. Signed-off-by:

Vladimir Oltean says: ==================== PTP driver refactoring for SJA1105 DSA This series creates a better separation between the driver core and the PTP portion. Therefore, users who are not interested in PTP can get a simpler and smaller driver by compiling it out. This is in preparation for further patches: SPI transfer timestamping, synchronizing the hardware clock (as opposed to keeping it free-running), PPS input/output, etc. ==================== Acked-by:

The PTP command register contains enable bits for: - Putting the 64-bit PTPCLKVAL register in add/subtract or write mode - Taking timestamps off of the corrected vs free-running clock - Starting/stopping the TTEthernet scheduling - Starting/stopping PPS output - Resetting the switch When a command needs to be issued (e.g. "change the PTPCLKVAL from write mode to add/subtract mode"), one cannot simply write to the command register setting the PTPCLKADD bit to 1, because that would zeroize the other settings. One also cannot do a read-modify-write (that would be too easy for this hardware) because not all bits of the command register are readable over SPI. So this leaves us with the only option of keeping the value of the PTP command register in the driver, and operating on that. Actually there are 2 types of PTP operations now: - Operations that modify the cached PTP command. These operate on ptp_data->cmd as a pointer. - Operations that apply all previously cached PTP settings, but don't otherwise cache what they did themselves. The sja1105_ptp_reset function is such an example. It copies the ptp_data->cmd on stack before modifying and writing it to SPI. This practically means that struct sja1105_ptp_cmd is no longer an implementation detail, since it needs to be stored in full into struct sja1105_ptp_data, and hence in struct sja1105_private. So the (*ptp_cmd) function prototype can change and take struct sja1105_ptp_cmd as second argument now. Signed-off-by:

The new rule (as already started for sja1105_tas.h) is for functions of optional driver components (ones which may be disabled via Kconfig - PTP and TAS) to take struct dsa_switch *ds instead of struct sja1105_private *priv as first argument. This is so that forward-declarations of struct sja1105_private can be avoided. So make sja1105_ptp.h the second user of this rule. Signed-off-by:

We need priv->ptp_caps to hold a structure and not just a pointer, because we use container_of in the various PTP callbacks. Therefore, the sja1105_ptp_caps structure declared in the global memory of the driver serves no further purpose after copying it into priv->ptp_caps. So just populate priv->ptp_caps with the needed operations and remove sja1105_ptp_caps. Signed-off-by:

Commit c10e6cf8 ("net: genetlink: push attrbuf allocation and parsing to a separate function") moved attribute buffer allocation and attribute parsing from genl_family_rcv_msg_doit() into a separate function genl_family_rcv_msg_attrs_parse() which, unlike the previous code, calls __nlmsg_parse() even if family->maxattr is 0 (i.e. the family does its own parsing). The parser error is ignored and does not propagate out of genl_family_rcv_msg_attrs_parse() but an error message ("Unknown attribute type") is set in extack and if further processing generates no error or warning, it stays there and is interpreted as a warning by userspace. Dumpit requests are not affected as genl_family_rcv_msg_dumpit() bypasses the call of genl_family_rcv_msg_attrs_parse() if family->maxattr is zero. Move this logic inside genl_family_rcv_msg_attrs_parse() so that we don't have to handle it in each caller. v3: put the check inside genl_family_rcv_msg_attrs_parse() v2: adjust also argument of genl_family_rcv_msg_attrs_free() Fixes: c10e6cf8 ("net: genetlink: push attrbuf allocation and parsing to a separate function") Signed-off-by:

tcp_zerocopy_receive() rounds down the zc->length a multiple of PAGE_SIZE. This results in two issues: - tcp_zerocopy_receive sets recv_skip_hint to the length of the receive queue if the zc->length input is smaller than the PAGE_SIZE, even though the data in receive queue could be zerocopied. - tcp_zerocopy_receive would set recv_skip_hint of 0, in cases where we have a little bit of data after the perfectly-sized packets. To fix these issues, do not store the rounded down value in zc->length. Round down the length passed to zap_page_range(), and return min(inq, zc->length) when the zap_range is 0. Signed-off-by:

The main reason for that - HOSTCC and CC have different aims. HOSTCC is used to build programs running on host, that can cross-comple target programs with CC. It was tested for arm and arm64 cross compilation, based on linaro toolchain, but should work for others. So, in order to split cross compilation (CC) with host build (HOSTCC), lets base samples on Makefile.target. It allows to cross-compile samples/bpf programs with CC while auxialry tools running on host built with HOSTCC. Signed-off-by:

The Makefile.target is added only and will be used in sample/bpf/Makefile later in order to switch cross-compiling to CC from HOSTCC environment. The HOSTCC is supposed to build binaries and tools running on the host afterwards, in order to simplify build or so, like "fixdep" or else. In case of cross compiling "fixdep" is executed on host when the rest samples should run on target arch. In order to build binaries for target arch with CC and tools running on host with HOSTCC, lets add Makefile.target for simplicity, having definition and routines similar to ones, used in script/Makefile.host. This allows later add cross-compilation to samples/bpf with minimum changes. The tprog stands for target programs built with CC. Makefile.target contains only stuff needed for samples/bpf, potentially can be reused later and now needed only for unblocking tricky samples/bpf cross compilation. Signed-off-by:

Let us remove `always += cookie_uid_helper_example.o`, which avoids breaking cross compilation due to mismatched includes. Signed-off-by:

echo should be replaced with echo -e to handle '\n' correctly, but instead, replace it with printf as some systems can't handle echo -e. Signed-off-by:

Implement "empty" and "dummy" reporters. The first one is really simple and does nothing. The other one has debugfs files to trigger breakage and it is able to do recovery. The ops also implement dummy fmsg content. Signed-off-by:
