| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | charge current This adds the ability to set the maximum constant charge current, supported by the battery, delivered by this battery power supply to the battery. The maximum constant charge current set in DT will also set the default constant charge current supplied by this supply. The actual user can modify the constant charge current within the range of 0 to maximum constant charge current via sysfs. The user can also modify the maximum constant charge current to widen the range of possible constant charge current. While this seems quite risky, a message is printed on the console to warn the user this might damage the battery. The reason for letting the user change the maximum constant charge current is for letting users change the battery and thus, let them adjust the maximum constant charge current according to what the battery can support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the CPCAP PMIC we can use the ADCs for monitoring the battery, and there is also a coulomb counter. So let's add basic support for the battery driver. I did not add any capacity prediction as that should probably be done in the user space. Or at least user space should tell the kernel some battery statistics and then the kernel driver could display the capacity based on that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apple currently supports three very common USB chargers: https://www.apple.com/power-adapters/ These chargers implement a proprietary Apple method for advertising 1A, 2.1A, and 2.4A at 5V called "Brick ID". In addition, 3rd parties implement the same charging method in many charging accessories that work with iOS devices. Devices that have charger detection chips such as the Pericom PI3USB9281, eg. Google Chromebook Pixel 2015, are capable of detecting these chargers, so let's add a type to facilicate passing that info up to userspace. This adds a separate power supply type for Apple's proprietary "Brick ID" charging method.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a file under debugfs to allow easy access to the erase count for each physical erase block on an UBI device. This is useful when debugging data integrity issues with UBIFS on NAND flash devices.

The problem is that ubi_scan_fastmap() moves the fastmap blocks from the scan_ai (allocated in scan_fast()) to the ai allocated in ubi_attach(). This results in two problems: - When the scan_ai is freed, aebs which were allocated from its slab cache are still in use. - When the other ai is being destroyed in destroy_ai(), the arguments to kmem_cache_free() call are incorrect since aebs on its ->fastmap list were allocated with a slab cache from a differnt ai. Fix this by making a copy of the aebs in ubi_scan_fastmap() instead of moving them. ============================================================================= BUG ubi_aeb_slab_cache (Not tainted): Objects remaining in ubi_aeb_slab_cache on __kmem_cache_shutdown() ----------------------------------------------------------------------------- INFO: Slab 0xbfd2da3c objects=17 used=1 fp=0xb33d7748 flags=0x40000080 CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<8026c47c>] (slab_err+0x78/0x88) [<8026c47c>] (slab_err) from [<802735bc>] (__kmem_cache_shutdown+0x180/0x3e0) [<802735bc>] (__kmem_cache_shutdown) from [<8024e13c>] (shutdown_cache+0x1c/0x60) [<8024e13c>] (shutdown_cache) from [<8024ed64>] (kmem_cache_destroy+0x19c/0x20c) [<8024ed64>] (kmem_cache_destroy) from [<8057cc14>] (destroy_ai+0x1dc/0x1e8) [<8057cc14>] (destroy_ai) from [<8057f04c>] (ubi_attach+0x3f4/0x450) [<8057f04c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) INFO: Object 0xb33d7e88 @offset=3720 INFO: Allocated in scan_peb+0x608/0x81c age=72 cpu=1 pid=118 kmem_cache_alloc+0x3b0/0x43c scan_peb+0x608/0x81c ubi_attach+0x124/0x450 ubi_attach_mtd_dev+0x60c/0xff8 ctrl_cdev_ioctl+0x110/0x2b8 do_vfs_ioctl+0xac/0xa00 SyS_ioctl+0x3c/0x64 ret_fast_syscall+0x0/0x1c kmem_cache_destroy ubi_aeb_slab_cache: Slab cache still has objects CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<8024ed80>] (kmem_cache_destroy+0x1b8/0x20c) [<8024ed80>] (kmem_cache_destroy) from [<8057cc14>] (destroy_ai+0x1dc/0x1e8) [<8057cc14>] (destroy_ai) from [<8057f04c>] (ubi_attach+0x3f4/0x450) [<8057f04c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) cache_from_obj: Wrong slab cache. ubi_aeb_slab_cache but object is from ubi_aeb_slab_cache ------------[ cut here ]------------ WARNING: CPU: 1 PID: 118 at mm/slab.h:354 kmem_cache_free+0x39c/0x450 Modules linked in: CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<80120e40>] (__warn+0xf4/0x10c) [<80120e40>] (__warn) from [<80120f20>] (warn_slowpath_null+0x28/0x30) [<80120f20>] (warn_slowpath_null) from [<80271fe0>] (kmem_cache_free+0x39c/0x450) [<80271fe0>] (kmem_cache_free) from [<8057cb88>] (destroy_ai+0x150/0x1e8) [<8057cb88>] (destroy_ai) from [<8057ef1c>] (ubi_attach+0x2c4/0x450) [<8057ef1c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) ---[ end trace 2bd8396277fd0a0b ]--- ============================================================================= BUG ubi_aeb_slab_cache (Tainted: G B W ): page slab pointer corrupt. ----------------------------------------------------------------------------- INFO: Allocated in scan_peb+0x608/0x81c age=104 cpu=1 pid=118 kmem_cache_alloc+0x3b0/0x43c scan_peb+0x608/0x81c ubi_attach+0x124/0x450 ubi_attach_mtd_dev+0x60c/0xff8 ctrl_cdev_ioctl+0x110/0x2b8 do_vfs_ioctl+0xac/0xa00 SyS_ioctl+0x3c/0x64 ret_fast_syscall+0x0/0x1c INFO: Slab 0xbfd2da3c objects=17 used=1 fp=0xb33d7748 flags=0x40000081 INFO: Object 0xb33d7e88 @offset=3720 fp=0xb33d7da0 Redzone b33d7e80: cc cc cc cc cc cc cc cc ........
