2021-07-06drm/i915: Use the correct IRQ during resumeThomas Zimmermann4-3/+12
The code in xcs_resume() probably didn't work as intended. It uses struct drm_device.irq, which is allocated to 0, but never initialized by i915 to the device's interrupt number. Change all calls to synchronize_hardirq() to intel_synchronize_irq(), which uses the correct interrupt. _hardirq() functions are not needed in this context. v5: * go back to _hardirq() after PCI probe reported wrong context; add rsp comment v4: * switch everything to intel_synchronize_irq() (Daniel) v3: * also use intel_synchronize_hardirq() at another callsite v2: * wrap irq code in intel_synchronize_hardirq() (Ville) Signed-off-by: Thomas Zimmermann <[email protected]> Fixes: 536f77b1caa0 ("drm/i915/gt: Call stop_ring() from ring resume, again") Cc: Chris Wilson <[email protected]> Cc: Mika Kuoppala <[email protected]> Cc: Daniel Vetter <[email protected]> Cc: Rodrigo Vivi <[email protected]> Cc: Joonas Lahtinen <[email protected]> Cc: Maarten Lankhorst <[email protected]> Cc: Lucas De Marchi <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 27e4b467d94e216b365da388358c9407af818662) Signed-off-by: Rodrigo Vivi <[email protected]>
2021-07-06drm/i915/display/dg1: Correctly map DPLLs during state readoutJosé Roberto de Souza2-6/+16
_DG1_DPCLKA0_CFGCR0 maps between DPLL 0 and 1 with one bit for phy A and B while _DG1_DPCLKA1_CFGCR0 maps between DPLL 2 and 3 with one bit for phy C and D. Reusing _cnl_ddi_get_pll() don't take that into cosideration returing DPLL 0 and 1 for phy C and D. That is a regression introduced in the refactor done in commit 351221ffc5e5 ("drm/i915: Move DDI clock readout to encoder->get_config()"). While at it also dropping the macros previously used, not reusing it to improve readability.

2021-07-06drm/i915/display: Do not zero past infoframes.vscKees Cook1-1/+1
intel_dp_vsc_sdp_unpack() was using a memset() size (36, struct dp_sdp) larger than the destination (24, struct drm_dp_vsc_sdp), clobbering fields in struct intel_crtc_state after infoframes.vsc. Use the actual target size for the memset().

2021-07-06arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAMMike Rapoport1-1/+3
The semantics of pfn_valid() is to check presence of the memory map for a PFN and not whether a PFN is in RAM. The memory map may be present for a hole in the physical memory and if such hole corresponds to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and fail: [ 2.863406] WARNING: CPU: 0 PID: 1 at arch/arm/mm/ioremap.c:287 __arm_ioremap_pfn_caller+0xf0/0x1dc [ 2.864812] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.13.0-09882-ga180bd1d7e16 #1 [ 2.865263] Hardware name: Generic DT based system [ 2.865711] Backtrace: [ 2.866063] [<80b07e58>] (dump_backtrace) from [<80b080ac>] (show_stack+0x20/0x24) [ 2.866633] r7:00000009 r6:0000011f r5:60000153 r4:80ddd1c0 [ 2.866922] [<80b0808c>] (show_stack) from [<80b18df0>] (dump_stack_lvl+0x58/0x74) [ 2.867117] [<80b18d98>] (dump_stack_lvl) from [<80b18e20>] (dump_stack+0x14/0x1c) [ 2.867309] r5:80118cac r4:80dc6774 [ 2.867404] [<80b18e0c>] (dump_stack) from [<80122fcc>] (__warn+0xe4/0x150) [ 2.867583] [<80122ee8>] (__warn) from [<80b08850>] (warn_slowpath_fmt+0x88/0xc0) [ 2.867774] r7:0000011f r6:80dc6774 r5:00000000 r4:814c4000 [ 2.867917] [<80b087cc>] (warn_slowpath_fmt) from [<80118cac>] (__arm_ioremap_pfn_caller+0xf0/0x1dc) [ 2.868158] r9:00000001 r8:9ef00000 r7:80e8b0d4 r6:0009ef00 r5:00000000 r4:00100000 [ 2.868346] [<80118bbc>] (__arm_ioremap_pfn_caller) from [<80118df8>] (__arm_ioremap_caller+0x60/0x68) [ 2.868581] r9:9ef00000 r8:821b6dc0 r7:00100000 r6:00000000 r5:815d1010 r4:80118d98 [ 2.868761] [<80118d98>] (__arm_ioremap_caller) from [<80118fcc>] (ioremap+0x28/0x30) [ 2.868958] [<80118fa4>] (ioremap) from [<8062871c>] (__devm_ioremap_resource+0x154/0x1c8) [ 2.869169] r5:815d1010 r4:814c5d2c [ 2.869263] [<806285c8>] (__devm_ioremap_resource) from [<8062899c>] (devm_ioremap_resource+0x14/0x18) [ 2.869495] r9:9e9f57a0 r8:814c4000 r7:815d1000 r6:815d1010 r5:8177c078 r4:815cf400 [ 2.869676] [<80628988>] (devm_ioremap_resource) from [<8091c6e4>] (fsi_master_acf_probe+0x1a8/0x5d8) [ 2.869909] [<8091c53c>] (fsi_master_acf_probe) from [<80723dbc>] (platform_probe+0x68/0xc8) [ 2.870124] r9:80e9dadc r8:00000000 r7:815d1010 r6:810c1000 r5:815d1010 r4:00000000 [ 2.870306] [<80723d54>] (platform_probe) from [<80721208>] (really_probe+0x1cc/0x470) [ 2.870512] r7:815d1010 r6:810c1000 r5:00000000 r4:815d1010 [ 2.870651] [<8072103c>] (really_probe) from [<807215cc>] (__driver_probe_device+0x120/0x1fc) [ 2.870872] r7:815d1010 r6:810c1000 r5:810c1000 r4:815d1010 [ 2.871013] [<807214ac>] (__driver_probe_device) from [<807216e8>] (driver_probe_device+0x40/0xd8) [ 2.871244] r9:80e9dadc r8:00000000 r7:815d1010 r6:810c1000 r5:812feaa0 r4:812fe994 [ 2.871428] [<807216a8>] (driver_probe_device) from [<80721a58>] (__driver_attach+0xa8/0x1d4) [ 2.871647] r9:80e9dadc r8:00000000 r7:00000000 r6:810c1000 r5:815d1054 r4:815d1010 [ 2.871830] [<807219b0>] (__driver_attach) from [<8071ee8c>] (bus_for_each_dev+0x88/0xc8) [ 2.872040] r7:00000000 r6:814c4000 r5:807219b0 r4:810c1000 [ 2.872194] [<8071ee04>] (bus_for_each_dev) from [<80722208>] (driver_attach+0x28/0x30) [ 2.872418] r7:810a2aa0 r6:00000000 r5:821b6000 r4:810c1000 [ 2.872570] [<807221e0>] (driver_attach) from [<8071f80c>] (bus_add_driver+0x114/0x200) [ 2.872788] [<8071f6f8>] (bus_add_driver) from [<80722ec4>] (driver_register+0x98/0x128) [ 2.873011] r7:81011d0c r6:814c4000 r5:00000000 r4:810c1000 [ 2.873167] [<80722e2c>] (driver_register) from [<80725240>] (__platform_driver_register+0x2c/0x34) [ 2.873408] r5:814dcb80 r4:80f2a764 [ 2.873513] [<80725214>] (__platform_driver_register) from [<80f2a784>] (fsi_master_acf_init+0x20/0x28) [ 2.873766] [<80f2a764>] (fsi_master_acf_init) from [<80f014a8>] (do_one_initcall+0x108/0x290) [ 2.874007] [<80f013a0>] (do_one_initcall) from [<80f01840>] (kernel_init_freeable+0x1ac/0x230) [ 2.874248] r9:80e9dadc r8:80f3987c r7:80f3985c r6:00000007 r5:814dcb80 r4:80f627a4 [ 2.874456] [<80f01694>] (kernel_init_freeable) from [<80b19f44>] (kernel_init+0x20/0x138) [ 2.874691] r10:00000000 r9:00000000 r8:00000000 r7:00000000 r6:00000000 r5:80b19f24 [ 2.874894] r4:00000000 [ 2.874977] [<80b19f24>] (kernel_init) from [<80100170>] (ret_from_fork+0x14/0x24) [ 2.875231] Exception stack(0x814c5fb0 to 0x814c5ff8) [ 2.875535] 5fa0: 00000000 00000000 00000000 00000000 [ 2.875849] 5fc0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 2.876133] 5fe0: 00000000 00000000 00000000 00000000 00000013 00000000 [ 2.876363] r5:80b19f24 r4:00000000 [ 2.876683] ---[ end trace b2f74b8536829970 ]--- [ 2.876911] fsi-master-acf gpio-fsi: ioremap failed for resource [mem 0x9ef00000-0x9effffff] [ 2.877492] fsi-master-acf gpio-fsi: Error -12 mapping coldfire memory [ 2.877689] fsi-master-acf: probe of gpio-fsi failed with error -12 Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN is in RAM or not.
