This patch set adds attributes of net device and gid type to each GID in the GID table. Users that use verbs directly need to specify the GID index. Since the same GID could have different types or associated net devices, users should have the ability to query the associated GID attributes. Adding these attributes to sysfs. Signed-off-by:

Previosuly, cm and cma modules supported only IB and RoCE v1 GID type. In order to support multiple GID types, the gid_type is passed to cm_init_av_by_path and stored in the path record. The rdma cm client would use a default GID type that will be saved in rdma_id_private. Signed-off-by:

In order to support multiple GID types, we need to store the gid_type with each GID. This is also aligned with the RoCE v2 annex "RoCEv2 PORT GID table entries shall have a "GID type" attribute that denotes the L3 Address type". The currently supported GID is IB_GID_TYPE_IB which is also RoCE v1 GID type. This implies that gid_type should be added to roce_gid_table meta-data. Signed-off-by:

Previously, we've searched the GID table twice: first when we searched the table for a GID matching the proposed new one, and second when we didn't find a match, we searched again for an empty GID slot in the table. Instead, search the table once noting the first empty slot as we search for our target GID. Signed-off-by:

Previously, IB GID cached used a lock per entry. This could result in spending a lot of CPU cycles for locking and unlocking just in order to find a GID. Changing this in favor of one lock per a GID table. Signed-off-by:

-
Steve Twiss authored
This fix alters the ordering of the IRQ and device registrations in the RTC driver probe function. This change will apply to the RTC driver that supports both DA9063 and DA9062 PMICs. A problem could occur with the existing RTC driver if: A system is started from a cold boot using the PMIC RTC IRQ to initiate a power on operation. For instance, if an RTC alarm is used to start a platform from power off. The existing driver IRQ is requested before the device has been properly registered. i.e. ret = devm_request_threaded_irq() comes before rtc->rtc_dev = devm_rtc_device_register(); In this case, the interrupt can be called before the device has been registered and the handler can be called immediately. The IRQ handler da9063_alarm_event() contains the function call rtc_update_irq(rtc->rtc_dev, 1, RTC_IRQF | RTC_AF); which in turn tries to access the unavailable rtc->rtc_dev. The fix is to reorder the functions inside the RTC probe. The IRQ is requested after the RTC device resource has been registered so that get_irq_byname is the last thing to happen. Signed-off-by:

In A.D. 1582 Pope Gregory XIII found that the existing Julian calendar insufficiently represented reality, and changed the rules about calculating leap years to account for this. Similarly, in A.D. 2013 Rockchip hardware engineers found that the new Gregorian calendar still contained flaws, and that the month of November should be counted up to 31 days instead. Unfortunately it takes a long time for calendar changes to gain widespread adoption, and just like more than 300 years went by before the last Protestant nation implemented Greg's proposal, we will have to wait a while until all religions and operating system kernels acknowledge the inherent advantages of the Rockchip system. Until then we need to translate dates read from (and written to) Rockchip hardware back to the Gregorian format. This patch works by defining Jan 1st, 2016 as the arbitrary anchor date on which Rockchip and Gregorian calendars are in sync. From that we can translate arbitrary later dates back and forth by counting the number of November/December transitons since the anchor date to determine the offset between the calendars. We choose this method (rather than trying to regularly "correct" the date stored in hardware) since it's the only way to ensure perfect time-keeping even if the system may be shut down for an unknown number of years. The drawback is that other software reading the same hardware (e.g. mainboard firmware) must use the same translation convention (including the same anchor date) to be able to read and write correct timestamps from/to the RTC.

When we also are I2C slave, we need to disable runtime PM because the address detection mechanism needs to be active all the time. However, we can reenable runtime PM once the slave instance was unregistered. So, use pm_runtime_get_sync/put to achieve this, since it has proper refcounting. pm_runtime_allow/forbid is like a global knob controllable from userspace which is unsuitable here. Signed-off-by:

Change the use of strncmp in zswap_pool_find_get() to strcmp. The use of strncmp is no longer correct, now that zswap_zpool_type is not an array; sizeof() will return the size of a pointer, which isn't the right length to compare. We don't need to use strncmp anyway, because the existing params and the passed in params are all guaranteed to be null terminated, so strcmp should be used. Signed-off-by:
