[PATCH 6.6.y] wifi: rtw89: pci: use DBI function for 8852AE/8852BE/8851BE

by Zenm Chen

From: Chin-Yen Lee <timlee(a)realtek.com> [ Upstream commit 9496d62f3877bc0f97b415bc04af98d092878026 ] Sometimes driver can't use kernel API pci_read/write_config_byte to access the PCI config space of above address 0x100 due to the negotiated PCI setting. 8852AE/8852BE/8851BE provide another way called DBI function, which belongs to WiFi mac and could access all PCI config space for this case.

[PATCH] drm/xe: Fix early wedge on GuC load failure

by Daniele Ceraolo Spurio

When the GuC fails to load we declare the device wedged. However, the very first GuC load attempt on GT0 (from xe_gt_init_hwconfig) is done before the GT1 GuC objects are initialized, so things go bad when the wedge code attempts to cleanup GT1. To fix this, check the initialization status in the functions called during wedge.

When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to send ABTS for each of them. On send completion, this causes an attempt to free the same frame twice that leads to a crash. Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS logic accordingly. Tested by checking MDS for FDMI information. Tested by using instrumented driver to: Drop PLOGI response Drop RHBA response Drop RPA response Drop RHBA and RPA response Drop PLOGI response + ABTS response Drop RHBA response + ABTS response Drop RPA response + ABTS response Drop RHBA and RPA response + ABTS response for both of them Fixes: 09c1e6ab4ab2 ("scsi: fnic: Add and integrate support for FDMI") Reviewed-by: Sesidhar Baddela <sebaddel(a)cisco.com> Reviewed-by: Arulprabhu Ponnusamy <arulponn(a)cisco.com> Reviewed-by: Gian Carlo Boffa <gcboffa(a)cisco.com> Tested-by: Arun Easi <aeasi(a)cisco.com> Co-developed-by: Arun Easi <aeasi(a)cisco.com> Signed-off-by: Arun Easi <aeasi(a)cisco.com> Tested-by: Karan Tilak Kumar <kartilak(a)cisco.com> Cc: <stable(a)vger.kernel.org> # 6.14.x Please see patch description Signed-off-by: Karan Tilak Kumar <kartilak(a)cisco.com> --- drivers/scsi/fnic/fdls_disc.c | 113 +++++++++++++++++++++++++--------- drivers/scsi/fnic/fnic_fdls.h | 1 + 2 files changed, 86 insertions(+), 28 deletions(-) diff --git a/drivers/scsi/fnic/fdls_disc.c b/drivers/scsi/fnic/fdls_disc.c index c2b6f4eb338e..0ee1b74967b9 100644 --- a/drivers/scsi/fnic/fdls_disc.c +++ b/drivers/scsi/fnic/fdls_disc.c @@ -763,47 +763,69 @@ static void fdls_send_fabric_abts(struct fnic_iport_s *iport) iport->fabric.timer_pending = 1; } -static void fdls_send_fdmi_abts(struct fnic_iport_s *iport) +static uint8_t *fdls_alloc_init_fdmi_abts_frame(struct fnic_iport_s *iport, + uint16_t oxid) { - uint8_t *frame; + struct fc_frame_header *pfdmi_abts; uint8_t d_id[3]; + uint8_t *frame; struct fnic *fnic = iport->fnic; - struct fc_frame_header *pfabric_abts; - unsigned long fdmi_tov; - uint16_t oxid; - uint16_t frame_size = FNIC_ETH_FCOE_HDRS_OFFSET + - sizeof(struct fc_frame_header); frame = fdls_alloc_frame(iport); if (frame == NULL) { FNIC_FCS_DBG(KERN_ERR, fnic->host, fnic->fnic_num, "Failed to allocate frame to send FDMI ABTS"); - return; + return NULL; } - pfabric_abts = (struct fc_frame_header *) (frame + FNIC_ETH_FCOE_HDRS_OFFSET); + pfdmi_abts = (struct fc_frame_header *) (frame + FNIC_ETH_FCOE_HDRS_OFFSET); fdls_init_fabric_abts_frame(frame, iport); hton24(d_id, FC_FID_MGMT_SERV); - FNIC_STD_SET_D_ID(*pfabric_abts, d_id); + FNIC_STD_SET_D_ID(*pfdmi_abts, d_id); + FNIC_STD_SET_OX_ID(*pfdmi_abts, oxid); + + return frame; +} + +static void fdls_send_fdmi_abts(struct fnic_iport_s *iport) +{ + uint8_t *frame; + unsigned long fdmi_tov; + uint16_t frame_size = FNIC_ETH_FCOE_HDRS_OFFSET + + sizeof(struct fc_frame_header); if (iport->fabric.fdmi_pending & FDLS_FDMI_PLOGI_PENDING) { - oxid = iport->active_oxid_fdmi_plogi; - FNIC_STD_SET_OX_ID(*pfabric_abts, oxid); + frame = fdls_alloc_init_fdmi_abts_frame(iport, + iport->active_oxid_fdmi_plogi); + if (frame == NULL) + return; + fnic_send_fcoe_frame(iport, frame, frame_size); } else { if (iport->fabric.fdmi_pending & FDLS_FDMI_REG_HBA_PENDING) { - oxid = iport->active_oxid_fdmi_rhba; - FNIC_STD_SET_OX_ID(*pfabric_abts, oxid); + frame = fdls_alloc_init_fdmi_abts_frame(iport, + iport->active_oxid_fdmi_rhba); + if (frame == NULL) + return; + fnic_send_fcoe_frame(iport, frame, frame_size); } if (iport->fabric.fdmi_pending & FDLS_FDMI_RPA_PENDING) { - oxid = iport->active_oxid_fdmi_rpa; - FNIC_STD_SET_OX_ID(*pfabric_abts, oxid); + frame = fdls_alloc_init_fdmi_abts_frame(iport, + iport->active_oxid_fdmi_rpa); + if (frame == NULL) { + if (iport->fabric.fdmi_pending & FDLS_FDMI_REG_HBA_PENDING) + goto arm_timer; + else + return; + } + fnic_send_fcoe_frame(iport, frame, frame_size); } } +arm_timer: fdmi_tov = jiffies + msecs_to_jiffies(2 * iport->e_d_tov); mod_timer(&iport->fabric.fdmi_timer, round_jiffies(fdmi_tov)); iport->fabric.fdmi_pending |= FDLS_FDMI_ABORT_PENDING; @@ -2244,6 +2266,21 @@ void fdls_fabric_timer_callback(struct timer_list *t) spin_unlock_irqrestore(&fnic->fnic_lock, flags); } +void fdls_fdmi_retry_plogi(struct fnic_iport_s *iport) +{ + struct fnic *fnic = iport->fnic; + + iport->fabric.fdmi_pending = 0; + /* If max retries not exhausted, start over from fdmi plogi */ + if (iport->fabric.fdmi_retry < FDLS_FDMI_MAX_RETRY) { + iport->fabric.fdmi_retry++; + FNIC_FCS_DBG(KERN_INFO, fnic->host, fnic->fnic_num, + "Retry FDMI PLOGI.

[PATCH v3] arm64: Restrict pagetable teardown to avoid false warning

by Dev Jain

Commit 9c006972c3fe removes the pxd_present() checks because the caller checks pxd_present(). But, in case of vmap_try_huge_pud(), the caller only checks pud_present(); pud_free_pmd_page() recurses on each pmd through pmd_free_pte_page(), wherein the pmd may be none. Thus it is possible to hit a warning in the latter, since pmd_none => !pmd_table(). Thus, add a pmd_present() check in pud_free_pmd_page(). This problem was found by code inspection.

[PATCH v2 0/2] Samsung Exynos 7870 DECON driver support

by Kaustabh Chakraborty

This patch series aims at adding support for Exynos7870's DECON in the Exynos7 DECON driver. It introduces a driver data struct so that support for DECON on other SoCs can be added to it in the future. It also fixes a few bugs in the driver, such as functions receiving bad pointers. Tested on Samsung Galaxy J7 Prime (samsung-on7xelte), Samsung Galaxy A2 Core (samsung-a2corelte), and Samsung Galaxy J6 (samsung-j6lte).
