xtensa: don't use linux IRQ #0

2017-06-17T04:39:38+00:00

commit e5c86679d5e864947a52fb31e45a425dea3e7fa9 upstream. Linux IRQ #0 is reserved for error reporting and may not be used. Increase NR_IRQS for one additional slot and increase irq_domain_add_legacy parameter first_irq value to 1, so that linux IRQ #0 is not associated with hardware IRQ #0 in legacy IRQ domains. Introduce macro XTENSA_PIC_LINUX_IRQ for static translation of xtensa PIC hardware IRQ # to linux IRQ #. Use this macro in XTFPGA platform data definitions. This fixes inability to use hardware IRQ #0 in configurations that don't use device tree and allows for non-identity mapping between linux IRQ # and hardware IRQ #.

r8152: avoid start_xmit to schedule napi when napi is disabled

2017-06-17T04:39:38+00:00

[ Upstream commit de9bf29dd6e4a8a874cb92f8901aed50a9d0b1d3 ] Stop the tx when the napi is disabled to prevent napi_schedule() is called. Signed-off-by: Hayes Wang Signed-off-by: David S. Miller Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

r8152: fix rtl8152_post_reset function

[ Upstream commit 2c561b2b728ca4013e76d6439bde2c137503745e ] The rtl8152_post_reset() should sumbit rx urb and interrupt transfer, otherwise the rx wouldn't work and the linking change couldn't be detected.

r8152: re-schedule napi for tx

2017-06-17T04:39:38+00:00

[ Upstream commit 248b213ad908b88db15941202ef7cb7eb137c1a0 ] Re-schedule napi after napi_complete() for tx, if it is necessay. In r8152_poll(), if the tx is completed after tx_bottom() and before napi_complete(), the scheduling of napi would be lost. Then, no one handles the next tx until the next napi_schedule() is called.

ravb: unmap descriptors when freeing rings

2017-06-17T04:39:38+00:00

[ Upstream commit a47b70ea86bdeb3091341f5ae3ef580f1a1ad822 ] "swiotlb buffer is full" errors occur after repeated initialisation of a device - f.e. suspend/resume or ip link set up/down. This is because memory mapped using dma_map_single() in ravb_ring_format() and ravb_start_xmit() is not released. Resolve this problem by unmapping descriptors when freeing rings.

drm/ast: Fixed system hanged if disable P2A

[ Upstream commit 6c971c09f38704513c426ba6515f22fb3d6c87d5 ] The original ast driver will access some BMC configuration through P2A bridge that can be disabled since AST2300 and after. It will cause system hanged if P2A bridge is disabled. Here is the update to fix it. Signed-off-by: Y.C. Chen Signed-off-by: Dave Airlie Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

drm/nouveau: Don't enabling polling twice on runtime resume

2017-06-17T04:39:37+00:00

[ Upstream commit cae9ff036eea577856d5b12860b4c79c5e71db4a ] As it turns out, on cards that actually have CRTCs on them we're already calling drm_kms_helper_poll_enable(drm_dev) from nouveau_display_resume() before we call it in nouveau_pmops_runtime_resume(). This leads us to accidentally trying to enable polling twice, which results in a potential deadlock between the RPM locks and drm_dev->mode_config.mutex if we end up trying to enable polling the second time while output_poll_execute is running and holding the mode_config lock. As such, make sure we only enable polling in nouveau_pmops_runtime_resume() if we need to.

[ Upstream commit d1156b489fa734d1af763d6a07b1637c01bb0aed ] init_ring(), refill_rx_ring() and start_tx() don't check if mapping dma memory succeed. The patch adds the checks and failure handling.
