2024-05-04wifi: rtw89: wow: refine WoWLAN flows of HCI interrupts and low power modeChih-Kang Chang
After enabling packet offload, the TX will be stuck after resume from WoWLAN mode. And the 8852c gets error messages like rtw89_8852ce 0000:04:00.0: No busy txwd pages available rtw89_8852ce 0000:04:00.0: queue 0 txwd 100 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 101 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 102 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 103 is not idle If suspend/resume many times that firmware will download failed and disconnection. To fix these issues, We removed the rtw89_hci_disable_intr() and rtw89_hci_enable_intr() during rtw89_wow_swap_fw() to prevent add packet offload can't receive c2h back due to interrupt disable. Only 8852C and 8922A needs to disable interrupt before downloading fw. Furthermore, we avoid using low power HCI mode on WoWLAN mode, to prevent interrupt enabled, then get interrupt and calculate RXBD mismatched due to software RXBD index already reset but hardware RXBD index not yet.

A late bug was reported by Robert Richter that the Restricted CXL Host (RCH) support was missing in the CXL endpoint access_coordinate calculation. The missing support causes the topology iterator to stumble over a NULL pointer and triggers a kernel OOPS on a platform with CXL 1.1 support. The fix bypasses RCH topology as the access_coordinate calculation is not necessary since RCH does not support hotplug and the memory region exported should be covered by the HMAT table already. A unit test is also added to cxl_test to check against future regressions on the topology iterator" * tag 'cxl-fixes-6.9-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl: Fix cxl_endpoint_get_perf_coordinate() support for RCH
2024-05-03Revert "net: mirror skb frag ref/unref helpers"Mina Almasry
This reverts commit a580ea994fd37f4105028f5a85c38ff6508a2b25. This revert is to resolve Dragos's report of page_pool leak here: https://lore.kernel.org/lkml/20240424165646.1625690-2-dtatulea@nvidia.com/ The reverted patch interacts very badly with commit 2cc3aeb5eccc ("skbuff: Fix a potential race while recycling page_pool packets"). The reverted commit hopes that the pp_recycle + is_pp_page variables do not change between the skb_frag_ref and skb_frag_unref operation. If such a change occurs, the skb_frag_ref/unref will not operate on the same reference type. In the case of Dragos's report, the grabbed ref was a pp ref, but the unref was a page ref, because the pp_recycle setting on the skb was changed. Attempting to fix this issue on the fly is risky. Lets revert and I hope to reland this with better understanding and testing to ensure we don't regress some edge case while streamlining skb reffing.

2024-05-03bnxt: fix bnxt_get_avail_msix() returning negative valuesDavid Wei
Current net-next/main does not boot for older chipsets e.g. Stratus. Sample dmesg: [ 11.368315] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): Able to reserve only 0 out of 9 requested RX rings [ 11.390181] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): Unable to reserve tx rings [ 11.438780] bnxt_en 0000:02:00.0 (unnamed net_device) (uninitialized): 2nd rings reservation failed.

[ 11.506012] bnxt_en 0000:02:00.0: probe with driver bnxt_en failed with error -12 This is caused by bnxt_get_avail_msix() returning a negative value for these chipsets not using the new resource manager i.e. !BNXT_NEW_RM. This in turn causes hwr.cp in __bnxt_reserve_rings() to be set to 0. In the current call stack, __bnxt_reserve_rings() is called from bnxt_set_dflt_rings() before bnxt_init_int_mode(). Therefore, bp->total_irqs is always 0 and for !BNXT_NEW_RM bnxt_get_avail_msix() always returns a negative number. Historically, MSIX vectors were requested by the RoCE driver during run-time and bnxt_get_avail_msix() was used for this purpose. Today, RoCE MSIX vectors are statically allocated. bnxt_get_avail_msix() should only be called for the BNXT_NEW_RM() case to reserve the MSIX ahead of time for RoCE use. bnxt_get_avail_msix() is also be simplified to handle the BNXT_NEW_RM() case only.

2024-05-03net: ks8851: Queue RX packets in IRQ handler instead of disabling BHsMarek Vasut
Currently the driver uses local_bh_disable()/local_bh_enable() in its IRQ handler to avoid triggering net_rx_action() softirq on exit from netif_rx(). The net_rx_action() could trigger this driver .start_xmit callback, which is protected by the same lock as the IRQ handler, so calling the .start_xmit from netif_rx() from the IRQ handler critical section protected by the lock could lead to an attempt to claim the already claimed lock, and a hang. The local_bh_disable()/local_bh_enable() approach works only in case the IRQ handler is protected by a spinlock, but does not work if the IRQ handler is protected by mutex, i.e. this works for KS8851 with Parallel bus interface, but not for KS8851 with SPI bus interface. Remove the BH manipulation and instead of calling netif_rx() inside the IRQ handler code protected by the lock, queue all the received SKBs in the IRQ handler into a queue first, and once the IRQ handler exits the critical section protected by the lock, dequeue all the queued SKBs and push them all into netif_rx(). At this point, it is safe to trigger the net_rx_action() softirq, since the netif_rx() call is outside of the lock that protects the IRQ handler.

The default device address apparently comes from the NVM configuration file and can differ quite a bit between controllers.

2024-05-03Bluetooth: qca: fix NVM configuration parsingJohan Hovold
The NVM configuration files used by WCN3988 and WCN3990/1/8 have two sets of configuration tags that are enclosed by a type-length header of type four which the current parser fails to account for. Instead the driver happily parses random data as if it were valid tags, something which can lead to the configuration data being corrupted if it ever encounters the words 0x0011 or 0x001b. As is clear from commit b63882549b2b ("Bluetooth: btqca: Fix the NVM baudrate tag offcet for wcn3991") the intention has always been to process the configuration data also for WCN3991 and WCN3998 which encodes the baud rate at a different offset. Fix the parser so that it can handle the WCN3xxx configuration files, which has an enclosing type-length header of type four and two sets of TLV tags enclosed by a type-length header of type two and three, respectively. Note that only the first set, which contains the tags the driver is currently looking for, will be parsed for now. With the parser fixed, the software in-band sleep bit will now be set for WCN3991 and WCN3998 (as it is for later controllers) and the default baud rate 3200000 may be updated by the driver also for WCN3xxx controllers. Notably the deep-sleep feature bit is already set by default in all configuration files in linux-firmware. Fixes: 4219d4686875 ("Bluetooth: btqca: Add wcn3990 firmware download support.")

2024-05-03Bluetooth: qca: fix wcn3991 device address checkJohan Hovold
Qualcomm Bluetooth controllers may not have been provisioned with a valid device address and instead end up using the default address 00:00:00:00:5a:ad. This address is now used to determine if a controller has a valid address or if one needs to be provided through devicetree or by user space before the controller can be used. It turns out that the WCN3991 controllers used in Chromium Trogdor machines use a different default address, 39:98:00:00:5a:ad, which also needs to be marked as invalid so that the correct address is fetched from the devicetree. Qualcomm has unfortunately not yet provided any answers as to whether the 39:98 encodes a hardware id and if there are other variants of the default address that needs to be handled by the driver. For now, add the Trogdor WCN3991 default address to the device address check to avoid having these controllers start with the default address instead of their assigned addresses.

When the dts file has multiple referrers to a single PD (e.g. simple-framebuffer and dss nodes both point to the DSS power-domain) the ti-sci driver will create two power domains, both with the same ID, and that will cause problems as one of the power domains will hide the other one. Fix this checking if a PD with the ID has already been created, and only create a PD for new IDs.

2024-05-03of: reserved_mem: Remove the use of phandle from the reserved_mem APIsOreoluwa Babatunde
The __find_rmem() function is the only place that references the phandle field of the reserved_mem struct. __find_rmem() is used to match a device_node object to its corresponding entry in the reserved_mem array using its phandle value. But, there is already a function called of_reserved_mem_lookup() which carries out the same action using the name of the node. Using the of_reserved_mem_lookup() function is more reliable because every node is guaranteed to have a name, but not all nodes will have a phandle. Nodes are only assigned a phandle if they are explicitly defined in the DT using "phandle = <phandle_number>", or if they are referenced by another node in the DT. Hence, If the phandle field is empty, then __find_rmem() will return a false negative. Hence, delete the __find_rmem() function and switch to using the of_reserved_mem_lookup() function to find the corresponding entry of a device_node in the reserved_mem array. Since the phandle field of the reserved_mem struct is now unused, delete that as well.

2024-05-03mmc: renesas_sdhi: Set the SDBUF after resetClaudiu Beznea
For development purpose, renesas_sdhi_probe() could be called w/ dma_ops = NULL to force the usage of PIO mode. In this case the renesas_sdhi_enable_dma() will not be called before transferring data. If renesas_sdhi_enable_dma() is not called, renesas_sdhi_clk_enable() call from renesas_sdhi_probe() will configure SDBUF by calling the renesas_sdhi_sdbuf_width() function, but then SDBUF will be reset in tmio_mmc_host_probe() when calling tmio_mmc_reset() though host->reset(). If SDBUF is zero the data transfer will not work in PIO mode for RZ/G3S. To fix this call again the renesas_sdhi_sdbuf_width(host, 16) in renesas_sdhi_reset(). The call of renesas_sdhi_sdbuf_width() was not removed from renesas_sdhi_clk_enable() as the host->reset() is optional.
