[PATCH v2] drivers/i915/intel_bios: Fix parsing backlight BDB data

by Karthikeyan Ramasubramanian

Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to backlight BDB data. Commit 700034566d68 ("drm/i915/bios: Define more BDB contents") updated the backlight BDB data accordingly. This broke the parsing of backlight BDB data in VBT for versions 236 - 238 (both inclusive) and hence the backlight controls are not responding on units with the concerned BDB version. backlight_control information has been present in backlight BDB data from at least BDB version 191 onwards, if not before. Hence this patch extracts the backlight_control information for BDB version 191 or newer. Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236). Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251).

[PATCH v3] can: mcp251xfd: fix infinite loop when xmit fails

by Vitor Soares

From: Vitor Soares <vitor.soares(a)toradex.com> When the mcp251xfd_start_xmit() function fails, the driver stops processing messages, and the interrupt routine does not return, running indefinitely even after killing the running application. Error messages: [ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16 [ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3). ... and repeat forever. The issue can be triggered when multiple devices share the same SPI interface. And there is concurrent access to the bus. The problem occurs because tx_ring->head increments even if mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX package while still expecting a response in mcp251xfd_handle_tefif_one(). This patch resolves the issue by decreasing tx_ring->head if mcp251xfd_start_xmit() fails. With the fix, if we trigger the issue and the err = -EBUSY, the driver returns NETDEV_TX_BUSY. The network stack retries to transmit the message. Otherwise, it prints an error and discards the message.

Add a new pci_set_power_state_locked() and associated helper functions that can be called with the PCI bus semaphore held to avoid taking the read lock twice.

[PATCH AUTOSEL 6.1 01/17] pinctrl: lochnagar: Don't build on MIPS

by Sasha Levin

From: Charles Keepax <ckeepax(a)opensource.cirrus.com> [ Upstream commit 6588732445ff19f6183f0fa72ddedf67e5a5be32 ] MIPS appears to define a RST symbol at a high level, which clashes with some register naming in the driver. Since there is currently no case for running this driver on MIPS devices simply cut off the build of this driver on MIPS.

Those functions then end up in INIT_TEXT and EXIT_TEXT respectively. We don't expect to see any profiled functions in EXIT_TEXT, so ftrace_init_nop() assumes that all addresses that aren't in the core kernel text belongs to a module. Since these functions do not match that criteria, we see the above bug. Address this by having ftrace ignore all locations in the text exit sections of vmlinux.

Freeing irqs before proceeding further in igb_clear_interrupt_scheme, fixes this problem. Signed-off-by: Imran Khan <imran.f.khan(a)oracle.com> --- This issue does not happen in v5.17 or later kernel versions because 'commit 9fb9eb4b59ac ("PCI/MSI: Let core code free MSI descriptors")', explicitly frees up MSI based irqs and hence indirectly fixes this issue as well. Also this is why I have mentioned this commit as equivalent upstream commit. But this upstream change itself is dependent on a bunch of changes starting from 'commit 288c81ce4be7 ("PCI/MSI: Move code into a separate directory")', which refactored msi driver into multiple parts. So another way of fixing this issue would be to backport these patches and get this issue implictly fixed. Kindly let me know if my current patch is not acceptable and in that case will it be fine if I backport the above mentioned msi driver refactoring patches to LST. drivers/net/ethernet/intel/igb/igb_main.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/net/ethernet/intel/igb/igb_main.c b/drivers/net/ethernet/intel/igb/igb_main.c index 7c42a99be5065..5b59fb65231ba 100644 --- a/drivers/net/ethernet/intel/igb/igb_main.c +++ b/drivers/net/ethernet/intel/igb/igb_main.c @@ -107,6 +107,7 @@ static int igb_setup_all_rx_resources(struct igb_adapter *); static void igb_free_all_tx_resources(struct igb_adapter *); static void igb_free_all_rx_resources(struct igb_adapter *); static void igb_setup_mrqc(struct igb_adapter *); +static void igb_free_irq(struct igb_adapter *adapter); static int igb_probe(struct pci_dev *, const struct pci_device_id *); static void igb_remove(struct pci_dev *pdev); static int igb_sw_init(struct igb_adapter *); @@ -1080,6 +1081,7 @@ static void igb_free_q_vectors(struct igb_adapter *adapter) */ static void igb_clear_interrupt_scheme(struct igb_adapter *adapter) { + igb_free_irq(adapter); igb_free_q_vectors(adapter); igb_reset_interrupt_capability(adapter); } -- 2.34.1

[PATCH 00/10] sparc64: Fix CPU online bug and warning fixes

by Sam Ravnborg via B4 Relay

Nick Bowler reported that sparc64 failed to bring all his CPU's online, and that turned out to be an easy fix. The sparc64 build was rather noisy with a lot of warnings which had irritated me enough to go ahead and fix them. With this set of patches my arch/sparc/ is almost warning free for all{no,yes,mod}config + defconfig builds. There is one warning about "clone3 not implemented", which I have ignored. The warning fixes hides the fact that sparc64 is not yet y2038 prepared, and it would be preferable if someone knowledgeable would fix this poperly. All fixes looks like 6.9 material to me.
