[PATCH] drm: Add 800x600 (SVGA) screen resolution to the built-in EDIDs

by Daniel Thompson

The 800x600 (SVGA) screen resolution was lacking in the set of built-in selectable EDID screen resolutions that can be used to repair misbehaving monitor firmware. This patch adds the related data set and expands the documentation. Note that the SVGA bit occupies a different byte to all the existing users of the established timing bits forcing a rework of the ESTABLISHED_TIMINGS_BITS macro. Tested new EDID on an aged (and misbehaving) industrial LCD panel; existing EDIDs still pass edid-decode's checksum checks.

[PATCH v2 0/7] armv7 BE kvm support

by Victor Kamensky

Hi Guys, Here is second version of series that enables KVM support for V7 big endian kernels. Mostly it deals with BE KVM host support. Marc Zyngier showed before with his patches how BE guest could run on top LE host. With these patches BE guest runs on top of BE host. If Marc's kvmtool is used with few additional changes I tested that BE host could run LE guest. Also I verified that there were no regressions in BE guest on top of LE host case. Note that posted series covers only kernel side changes. The changes were tested inside of bigger setup with additional changes in qemu and kvmtool. I will post those changes separately in proper aliases but for completeness sake Appendix A gives pointers to git repositories and branches with all needed changes. Changes since V1: 1) Patch that handles issue of including assembler.h into kvm .S file now handled separately. It was posted before on mailing list [1]. This series depend on it. 2) Incorporated most of Christoffer V1 review comments. The only thing I did not do wrt Christoffer's suggestion is possible rework of 'one_reg coproc set and get BE fixes' patch. I think I put better explanation on what my code does, and if it is still not good we will go from there. 3) Moved rr_lo_hi macro into arch/arm/include/asm/kvm_asm.h along the lines Christoffer suggested 4) Split 'fix KVM assembler files to work in BE case' patch into 4 smaller one each handling one logic issue.

[PATCH v7 0/3] Add support for PCI in AArch64

by Liviu Dudau

Hi, This patch adds support for PCI to AArch64. It is based on my v7 patch that adds support for creating generic host bridge structure from device tree. With that in place, I was able to boot a platform that has PCIe host bridge support and use a PCIe network card. I have dropped the RFC tag from the subject as I now have the ambitious goal of trying to get it mainlined. Changes from v6: - Guard the pci_domain_nr() inline implementation with #ifdef CONFIG_PCI as to avoid conflict with default empty version present in include/linux/pci.h. Thanks to Jingoo Han for catching this. Changes from v5: - Removed pcibios_fixup_bridge_ranges() as the week default version is fine. - Removed the ALIGN() call in pcibios_align_resource() - Stopped exporting pcibios_align_resource() Changes from v4: - Fixed the pci_domain_nr() implementation for arm64. Now we use find_pci_host_bride() to find the host bridge before we retrieve the domain number. Changes from v3: - Added Acks accumulated so far ;) - Still carrying Catalin's patch for moving the PCI_IO_BASE until it lands in linux-next or mainline, in order to ease applying the series Changes from v2: - Implement an arch specific version of pci_register_io_range() and pci_address_to_pio(). - Return 1 from pci_proc_domain(). Changes from v1: - Added Catalin's patch for moving the PCI_IO_BASE location and extend its size to 16MB - Integrated Arnd's version of pci_ioremap_io that uses a bitmap for keeping track of assigned IO space and returns an io_offset. At the moment the code is added in arch/arm64 but it can be moved in drivers/pci. - Added a fix for the generic ioport_map() function when !CONFIG_GENERIC_IOMAP as suggested by Arnd. v6 thread here: https://lkml.org/lkml/2014/3/5/41 v5 thread here: https://lkml.org/lkml/2014/3/4/307 v4 thread here: https://lkml.org/lkml/2014/3/3/298 v3 thread here: https://lkml.org/lkml/2014/2/28/211 v2 thread here: https://lkml.org/lkml/2014/2/27/255 v1 thread here: https://lkml.org/lkml/2014/2/3/389 The API used is different from the one used by ARM architecture. There is no pci_common_init_dev() function and no hw_pci structure, as that is no longer needed. Once the last signature is added to the legal agreement, I will post the host bridge driver code that I am using. Meanwhile, here is an example of what the probe function looks like, posted as an example: static int myhostbridge_probe(struct platform_device *pdev) { int err; struct device_node *dev; struct pci_host_bridge *bridge; struct myhostbridge_port *pp; resource_size_t lastbus; dev = pdev->dev.of_node; if (!of_device_is_available(dev)) { pr_warn("%s: disabled\n", dev->full_name); return -ENODEV; } pp = kzalloc(sizeof(struct myhostbridge_port), GFP_KERNEL); if (!pp) return -ENOMEM; bridge = of_create_pci_host_bridge(&pdev->dev, &myhostbridge_ops, pp); if (IS_ERR(bridge)) { err = PTR_ERR(bridge); goto bridge_create_fail; } err = myhostbridge_setup(bridge->bus); if (err) goto bridge_setup_fail; /* We always enable PCI domains and we keep domain 0 backward * compatible in /proc for video cards */ pci_add_flags(PCI_ENABLE_PROC_DOMAINS); pci_add_flags(PCI_REASSIGN_ALL_BUS | PCI_REASSIGN_ALL_RSRC); lastbus = pci_scan_child_bus(bridge->bus); pci_bus_update_busn_res_end(bridge->bus, lastbus); pci_assign_unassigned_bus_resources(bridge->bus); pci_bus_add_devices(bridge->bus); return 0; bridge_setup_fail: put_device(&bridge->dev); device_unregister(&bridge->dev); bridge_create_fail: kfree(pp); return err; } Best regards, Liviu Catalin Marinas (1): arm64: Extend the PCI I/O space to 16MB Liviu Dudau (2): Fix ioport_map() for !CONFIG_GENERIC_IOMAP cases. arm64: Add architecture support for PCI Documentation/arm64/memory.txt | 16 +-- arch/arm64/Kconfig | 19 +++- arch/arm64/include/asm/Kbuild | 1 + arch/arm64/include/asm/io.h | 5 +- arch/arm64/include/asm/pci.h | 51 +++++++++ arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/pci.c | 173 +++++++++++++++++++++++++++++++ include/asm-generic/io.h | 2 +- 8 files changed, 258 insertions(+), 10 deletions(-) create mode 100644 arch/arm64/include/asm/pci.h create mode 100644 arch/arm64/kernel/pci.c -- 1.9.0

[PATCH 0/4] arm64: Add audit support

by AKASHI Takahiro

This patchset adds audit support on arm64. The implementation is just like in other architectures, and so I think little explanation is needed. I verified this patch with some commands on both 64-bit rootfs and 32-bit rootfs(, but only in little-endian): # auditctl -a exit,always -S openat -F path=/etc/inittab # auditctl -a exit,always -F dir=/tmp -F perm=rw # auditctl -a task,always # autrace /bin/ls What else? (Thanks to Clayton for his cross-compiling patch) I'd like to discuss about the following issues: (issues) * AUDIT_ARCH_* Why do we need to distiguish big-endian and little-endian? [2/4] * AArch32 We need to add a check for identifying the endian in 32-bit tasks. [3/4] * syscall no in AArch32 Currently all the definitions are added in unistd32.h with "ifdef __AARCH32_AUDITSYSCALL" to use asm-generic/audit_*.h. [3/4] "ifdef" is necessary to avoid a conflict with 64-bit definitions. Do we need a more sophisticated way? * TIF_AUDITSYSCALL Most architectures, except x86, do not check TIF_AUDITSYSCALL. Why not? [4/4] * Userspace audit package There are some missing syscall definitions in lib/aarch64_table.h. There is no support for AUDIT_ARCH_ARM (I mean LE. armeb is BE).

[PATCH V2] clocksource: register cpu notifier to remove timer from dying CPU

by Viresh Kumar

clocksource core is using add_timer_on() to run clocksource_watchdog() on all CPUs one by one. But when a core is brought down, clocksource core doesn't remove this timer from the dying CPU. And in this case timer core gives this (Gives this only with unmerged code, anyway in the current code as well timer core is migrating a pinned timer to other CPUs, which is also wrong: http://www.gossamer-threads.com/lists/linux/kernel/1898117) migrate_timer_list: can't migrate pinned timer: ffffffff81f06a60, timer->function: ffffffff810d7010,deactivating it Modules linked in: CPU: 0 PID: 1932 Comm: 01-cpu-hotplug Not tainted 3.14.0-rc1-00088-gab3c4fd #4 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 0000000000000009 ffff88001d407c38 ffffffff817237bd ffff88001d407c80 ffff88001d407c70 ffffffff8106a1dd 0000000000000010 ffffffff81f06a60 ffff88001e04d040 ffffffff81e3d4c0 ffff88001e04d030 ffff88001d407cd0 Call Trace: [<ffffffff817237bd>] dump_stack+0x4d/0x66 [<ffffffff8106a1dd>] warn_slowpath_common+0x7d/0xa0 [<ffffffff8106a24c>] warn_slowpath_fmt+0x4c/0x50 [<ffffffff810761c3>] ? __internal_add_timer+0x113/0x130 [<ffffffff810d7010>] ? clocksource_watchdog_kthread+0x40/0x40 [<ffffffff8107753b>] migrate_timer_list+0xdb/0xf0 [<ffffffff810782dc>] timer_cpu_notify+0xfc/0x1f0 [<ffffffff8173046c>] notifier_call_chain+0x4c/0x70 [<ffffffff8109340e>] __raw_notifier_call_chain+0xe/0x10 [<ffffffff8106a3f3>] cpu_notify+0x23/0x50 [<ffffffff8106a44e>] cpu_notify_nofail+0xe/0x20 [<ffffffff81712a5d>] _cpu_down+0x1ad/0x2e0 [<ffffffff81712bc4>] cpu_down+0x34/0x50 [<ffffffff813fec54>] cpu_subsys_offline+0x14/0x20 [<ffffffff813f9f65>] device_offline+0x95/0xc0 [<ffffffff813fa060>] online_store+0x40/0x90 [<ffffffff813f75d8>] dev_attr_store+0x18/0x30 [<ffffffff8123309d>] sysfs_kf_write+0x3d/0x50 This patch tries to fix this by registering cpu notifiers from clocksource core, only when we start clocksource-watchdog.
