2020-10-29coresight: Fix uninitialised pointer bug in etm_setup_aux()Mike Leach1-1/+1
Commit [bb1860efc817] changed the sink handling code introducing an uninitialised pointer bug. This results in the default sink selection failing. Prior to commit: static void etm_setup_aux(...) <snip> struct coresight_device *sink; <snip> /* First get the selected sink from user space. */ if (event->attr.config2) { id = (u32)event->attr.config2; sink = coresight_get_sink_by_id(id); } else { sink = coresight_get_enabled_sink(true); } <ctd> *sink always initialised - possibly to NULL which triggers the automatic sink selection. After commit: static void etm_setup_aux(...) <snip> struct coresight_device *sink; <snip> /* First get the selected sink from user space. */ if (event->attr.config2) { id = (u32)event->attr.config2; sink = coresight_get_sink_by_id(id); } <ctd> *sink pointer uninitialised when not providing a sink on the perf command line. This breaks later checks to enable automatic sink selection.

2020-10-29r8169: fix issue with forced threading in combination with shared interruptsHeiner Kallweit1-2/+2
As reported by Serge flag IRQF_NO_THREAD causes an error if the interrupt is actually shared and the other driver(s) don't have this flag set. This situation can occur if a PCI(e) legacy interrupt is used in combination with forced threading. There's no good way to deal with this properly, therefore we have to remove flag IRQF_NO_THREAD. For fixing the original forced threading issue switch to napi_schedule().

2020-10-29ibmvnic: fix ibmvnic_set_macLijun Pan1-2/+6
Jakub Kicinski brought up a concern in ibmvnic_set_mac(). ibmvnic_set_mac() does this: ether_addr_copy(adapter->mac_addr, addr->sa_data); if (adapter->state != VNIC_PROBED) rc = __ibmvnic_set_mac(netdev, addr->sa_data); So if state == VNIC_PROBED, the user can assign an invalid address to adapter->mac_addr, and ibmvnic_set_mac() will still return 0. The fix is to validate ethernet address at the beginning of ibmvnic_set_mac(), and move the ether_addr_copy to the case of "adapter->state != VNIC_PROBED".

2020-10-29drm/i915: Restore ILK-M RPS supportVille Syrjälä1-0/+1
Restore RPS for ILK-M. We lost it when an extra HAS_RPS() check appeared in intel_rps_enable(). Unfortunaltey this just makes the performance worse on my ILK because intel_ips insists on limiting the GPU freq to the minimum. If we don't do the RPS init then intel_ips will not limit the frequency for whatever reason. Either it can't get at some required information and thus makes wrong decisions, or we mess up some weights/etc. and cause it to make the wrong decisions when RPS init has been done, or the entire thing is just wrong. Would require a bunch of reverse engineering to figure out what's going on.

2020-10-29drm/i915/region: fix max size calculationMatthew Auld3-2/+79
We are incorrectly limiting the max allocation size as per the mm max_order, which is effectively the largest power-of-two that we can fit in the region size. However, it's normal to setup the region or allocator with a non-power-of-two size(for example 3G), which we should already handle correctly, except it seems for the early too-big-check. v2: make sure we also exercise the I915_BO_ALLOC_CONTIGUOUS path, which is quite different, since for that we are actually limited by the largest power-of-two that we can fit within the region size.

2020-10-29drm/ttm: new TT backend allocation pool v3Christian König3-1/+671
This replaces the spaghetti code in the two existing page pools. First of all depending on the allocation size it is between 3 (1GiB) and 5 (1MiB) times faster than the old implementation. It makes better use of buddy pages to allow for larger physical contiguous allocations which should result in better TLB utilization at least for amdgpu. Instead of a completely braindead approach of filling the pool with one CPU while another one is trying to shrink it we only give back freed pages. This also results in much less locking contention and a trylock free MM shrinker callback, so we can guarantee that pages are given back to the system when needed. Downside of this is that it takes longer for many small allocations until the pool is filled up. We could address this, but I couldn't find an use case where this actually matters. We also don't bother freeing large chunks of pages any more since the CPU overhead in that path isn't really that important. The sysfs files are replaced with a single module parameter, allowing users to override how many pages should be globally pooled in TTM. This unfortunately breaks the UAPI slightly, but as far as we know nobody ever depended on this. Zeroing memory coming from the pool was handled inconsistently. The alloc_pages() based pool was zeroing it, the dma_alloc_attr() based one wasn't. For now the new implementation isn't zeroing pages from the pool either and only sets the __GFP_ZERO flag when necessary. The implementation has only 768 lines of code compared to the over 2600 of the old one, and also allows for saving quite a bunch of code in the drivers since we don't need specialized handling there any more based on kernel config. Additional to all of that there was a neat bug with IOMMU, coherent DMA mappings and huge pages which is now fixed in the new code as well. v2: make ttm_pool_apply_caching static as reported by the kernel bot, add some more checks v3: fix some more checkpatch.pl warnings Signed-off-by: Christian König <[email protected]> Reviewed-by: Dave Airlie <[email protected]> Reviewed-by: Madhav Chauhan <[email protected]> Tested-by: Huang Rui <[email protected]> Link: https://patchwork.freedesktop.org/patch/397080/?series=83051&rev=1

IRQ is not supposed to be changed at runtime, so there is no functional change in ace_fsm_yieldirq(). On the other hand we now take first resources instead of last ones to proceed. I can't imagine how broken should be firmware to have a garbage in the first resource slots. But if it the case, it needs to be documented.

2020-10-29null_blk: Fix locking in zoned modeDamien Le Moal2-25/+82
When the zoned mode is enabled in null_blk, Serializing read, write and zone management operations for each zone is necessary to protect device level information for managing zone resources (zone open and closed counters) as well as each zone condition and write pointer position. Commit 35bc10b2eafb ("null_blk: synchronization fix for zoned device") introduced a spinlock to implement this serialization. However, when memory backing is also enabled, GFP_NOIO memory allocations are executed under the spinlock, resulting in might_sleep() warnings. Furthermore, the zone_lock spinlock is locked/unlocked using spin_lock_irq/spin_unlock_irq, similarly to the memory backing code with the nullb->lock spinlock. This nested use of irq locks wrecks the irq enabled/disabled state. Fix all this by introducing a bitmap for per-zone lock, with locking implemented using wait_on_bit_lock_io() and clear_and_wake_up_bit(). This locking mechanism allows keeping a zone locked while executing null_process_cmd(), serializing all operations to the zone while allowing to sleep during memory backing allocation with GFP_NOIO. Device level zone resource management information is protected using a spinlock which is not held while executing null_process_cmd(); Fixes: 35bc10b2eafb ("null_blk: synchronization fix for zoned device") Signed-off-by: Damien Le Moal <[email protected]> Signed-off-by: Jens Axboe <[email protected]>

2020-10-29usb: typec: stusb160x: fix signedness comparison issue with enum variablesAmelie Delaunay1-12/+8
chip->port_type and chip->pwr_opmode are enums and when GCC considers them as unsigned, the conditions are never met. This patch takes advantage of the ret variable and fixes the following warnings: drivers/usb/typec/stusb160x.c:548 stusb160x_get_fw_caps() warn: unsigned 'chip->port_type' is never less than zero. drivers/usb/typec/stusb160x.c:570 stusb160x_get_fw_caps() warn: unsigned 'chip->pwr_opmode' is never less than zero.

`width` and `height` are defined as unsigned in our UAPI font descriptor `struct console_font`. Make them unsigned in our kernel font descriptor `struct font_desc`, too. Also, change the corresponding printk() format identifiers from `%d` to `%u`, in sti_select_fbfont().

This patch removes the MIC drivers from the kernel tree since the corresponding devices have been discontinued. Removing the dma and char-misc changes in one patch and merging via the char-misc tree is best to avoid any potential build breakage.
