When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Also, there is no need to store the individual debugfs file name, just remove the whole directory all at once, saving a local variable. Cc: "David S.

In case of a timeout currently ~0 is returned. Callers often just check whether a certain bit is set and therefore may behave incorrectly. So let's return -ETIMEDOUT in case of a timeout. r8168_phy_ocp_read is used in r8168g_mdio_read only, therefore we can apply the same change. Signed-off-by:

The packing facility is needed to decode Ethernet meta frames containing source port and RX timestamping information. The DSA driver selects CONFIG_PACKING, but the tagger did not, and since taggers can be now compiled as modules independently from the drivers themselves, this is an issue now, as CONFIG_PACKING is disabled by default on all architectures. Fixes: e53e18a6 ("net: dsa: sja1105: Receive and decode meta frames") Signed-off-by:

We were accessing the pointer returned from platform_get_resource before checking if it was valid, causing an oops if it was not. Move this access after the call to devm_ioremap_resource which does the validity check. Signed-off-by:

Julian Wiedmann says: ==================== s390/qeth: updates 2019-06-11 please apply the following patch series for qeth to net-next. This brings all sorts of cleanups and minor improvements, primarily for the control IO path. ==================== Signed-off-by: -

We statically allocate 8 cmd buffers on the read channel, when the only IO left that's still using them is the long-running READ. Replace this with a single allocated cmd, that gets restarted whenever the READ completed. This introduces refcounting for allocated cmds, so that the READ cmd can survive the IO completion.

The current IDX sequence first sends one WRITE cmd to activate the device, and then sends a second cmd that READs the response. Using qeth_alloc_cmd(), we can combine this into a single IO with two command-chained CCWs. Signed-off-by:

Julian Wiedmann authored
The RCD code is the last remaining IO path that doesn't use the qeth_send_control_data() infrastructure. Doing so allows us to remove all sorts of custom state machinery and logic in the IRQ handler. Instead of introducing statically allocated cmd buffers for this single IO on the data channel, use the new qeth_alloc_cmd() helper. Signed-off-by:
-
Julian Wiedmann authored
qeth currently uses a fixed set of statically allocated cmd buffers for the read and write IO channels. This (1) doesn't play well with the single RCD cmd we need to issue on the data channel, (2) doesn't provide the necessary flexibility for certain IDX improvements, and (3) is also rather wasteful since the buffers are idle most of the time. Add a new type of cmd buffer that is dynamically allocated, and keeps its ccw chain in the DMA data area. Since this touches most callers of qeth_setup_ccw(), also add a new CCW flags parameter for future usage. Signed-off-by:

Each cmd buffer maintains a pointer to the IO channel that it was/will be issued on. So when dealing with cmd buffers, we don't need to pass around a separate channel pointer. Signed-off-by:

The vast majority of SETUP-classified trace entries can be moved to their device-specific trace file. This reduces pollution of the global SETUP file, and provides a consistent trace view of all activity on the device. Signed-off-by:

OSN currently provides a custom code path to submit IPA cmds, without waiting for the cmd response. Replace it with qeth_send_ipa_cmd(), which uses the common qeth_send_control_data() IO infrastructure. By setting a custom iob->callback, we can now provide feedback to the caller about whether the cmd has been successfully submitted to HW. Since the callback then immediately wakes up the reply-waiter object, we maintain the old behaviour of returning early without waiting for the response. Signed-off-by:

Julian Wiedmann authored
The basic MPC initialization sequence is strictly sequential, and waiting for an available cmd buffer should never be necessary. So this change only affects the OSN path, where dangling waiters on an unbounded wait_event() are not desirable. Switch to qeth_get_buffers(), and let OSN callers deal with -ENOMEM. Signed-off-by:

When called from qeth_core_probe_device(), qeth_determine_capabilities() initializes the device's BLKT defaults. From all other callers, the ccw_device has already been set online and the BLKT setting is skipped. Clean this up by extracting the BLKT setting into a separate helper that gets called from the right place. Signed-off-by:

Julian Wiedmann authored
The completion of a pending READ cmd is processed via qeth_issue_next_read_cb(). Let this callback also start the next READ cmd, instead of hardcoding that step into the IRQ handler. While at it remove the check of the channel state, __qeth_issue_next_read() already does this. Signed-off-by:

When the tear down sequence in qeth_l?_stop_card() has finished, the card is guaranteed to be in DOWN state and we don't have to check for it again. With this insight we can also remove the redundant setting of card->state in qeth_l?_set_online()'s error path. Signed-off-by:

Current code suppresses debug entries when an TX buffer completes in ERROR state with no error indication set in SBALF15. This was introduced back with commit 58490f18 ("qeth: HiperSockets SIGA retry support on CC=2."). But qeth no longer retries after CC=2, and this sort of suppression make no sense anymore. Remove it.

Ido Schimmel says: ==================== mlxsw: Add support for physical hardware clock Shalom says: This patchset adds support for physical hardware clock for Spectrum-1 ASIC only. Patches #1, #2 and #3 add the ability to query the free running clock PCI address. Patches #4 and #5 add two new register, the Management UTC Register and the Management Pulse Per Second Register. Patch #6 publishes scaled_ppm_to_ppb() to allow drivers to use it. Patch #7 adds the physical hardware clock operations. Patch #8 initializes the physical hardware clock. Patch #9 adds a selftest for testing the PTP physical hardware clock. v2 (Richard): * s/ptp_clock_scaled_ppm_to_ppb/scaled_ppm_to_ppb/ * imply PTP_1588_CLOCK in mlxsw Kconfig * s/mlxsw_sp1_ptp_update_phc_settime/mlxsw_sp1_ptp_phc_settime/ * s/mlxsw_sp1_ptp_update_phc_adjfreq/mlxsw_sp1_ptp_phc_adjfreq/ ==================== Signed-off-by: -

Test the PTP Physical Hardware Clock functionality using the "phc_ctl" (a part of "linuxptp"). The test contains three sub-tests: * "settime" test * "adjtime" test * "adjfreq" test "settime" test: * set the PHC time to 0 seconds. * wait for 120.5 seconds. * check if PHC time equal to 120.XX seconds. "adjtime" test: * set the PHC time to 0 seconds. * adjust the time by 10 seconds. * check if PHC time equal to 10.XX seconds. "adjfreq" test: * adjust the PHC frequency to be 1% faster. * set the PHC time to 0 seconds. * wait for 100.5 seconds. * check if PHC time equal to 101.XX seconds. Usage: $ ./phc.sh /dev/ptp<X> It is possible to run a subset of the tests, for example: * To run only the "settime" test: $ TESTS="settime" ./phc.sh /dev/ptp<X> Signed-off-by:Shalom Toledo <shalomt@mellanox.com> Reviewed-by:
