Some Acer models require an additional command to turn off the fan after bios mode has been enabled. Adding new section in bios table to allow support for those models, by writing an extra "manual mode" register.

added following new models: * Aspire 5755G * AO521 * AO751h * Aspire One 753 * Extensa 5420 * Aspire 5315 * Aspire 5739G * TravelMate TM8573T Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andreas Mohr <andi@lisas.de> Acked-by: Borislav Petkov <bp@suse.de> Signed-off-by: Peter Feuerer <peter@piie.net>
acerhdf has been doing an on-off fan control using hysteresis by post-manipulating the outcome of thermal subsystem trip point handling. This patch enables acerhdf to use the bang-bang governor, which is intended for on-off controlled fans.

added critical trip point which represents the temperature limit. Added return -EINVAL in case wrong trip point is provided.

* renamed bios_settings_t to bios_settings, as it is no typedef
* replaced "unsigned char" by u8 in bios_settings struct for better
readability.

Since limited tracking device per condition, this feature is to support tracking multiple devices concurrently. When a pattern monitor detects the device, this feature issues an address monitor for tracking that device. Let pattern monitor can keep monitor new devices. This feature adds an address filter when receiving a LE monitor device event which monitor handle is for a pattern, and the controller started monitoring the device. And this feature also has cancelled the monitor advertisement from address filters when receiving a LE monitor device event when the controller stopped monitoring the device specified by an address and monitor handle.

Since limited tracking device per condition, this feature is to support tracking multiple devices concurrently. When a pattern monitor detects the device, this feature issues an address monitor for tracking that device. Let pattern monitor can keep monitor new devices.

Recently, when running './test_progs -j', I occasionally hit the following errors: test_lwt_redirect:PASS:pthread_create 0 nsec test_lwt_redirect_run:FAIL:netns_create unexpected error: 256 (errno 0) torvalds#142/2 lwt_redirect/lwt_redirect_normal_nomac:FAIL torvalds#142 lwt_redirect:FAIL test_lwt_reroute:PASS:pthread_create 0 nsec test_lwt_reroute_run:FAIL:netns_create unexpected error: 256 (errno 0) test_lwt_reroute:PASS:pthread_join 0 nsec torvalds#143/2 lwt_reroute/lwt_reroute_qdisc_dropped:FAIL torvalds#143 lwt_reroute:FAIL The netns_create() definition looks like below: #define NETNS "ns_lwt" static inline int netns_create(void) { return system("ip netns add " NETNS); } One possibility is that both lwt_redirect and lwt_reroute create netns with the same name "ns_lwt" which may cause conflict. I tried the following example: $ sudo ip netns add abc $ echo $? 0 $ sudo ip netns add abc Cannot create namespace file "/var/run/netns/abc": File exists $ echo $? 1 $ The return code for above netns_create() is 256. The internet search suggests that the return value for 'ip netns add ns_lwt' is 1, which matches the above 'sudo ip netns add abc' example. This patch tried to use different netns names for two tests to avoid 'ip netns add <name>' failure. I ran './test_progs -j' 10 times and all succeeded with lwt_redirect/lwt_reroute tests.

During the PCI AER system's error recovery process, the kernel driver may encounter a race condition with freeing the reset_data structure's memory. If the device restart will take more than 10 seconds the function scheduling that restart will exit due to a timeout, and the reset_data structure will be freed. However, this data structure is used for completion notification after the restart is completed, which leads to a UAF bug. This results in a KFENCE bug notice. BUG: KFENCE: use-after-free read in adf_device_reset_worker+0x38/0xa0 [intel_qat] Use-after-free read at 0x00000000bc56fddf (in kfence-torvalds#142): adf_device_reset_worker+0x38/0xa0 [intel_qat] process_one_work+0x173/0x340 To resolve this race condition, the memory associated to the container of the work_struct is freed on the worker if the timeout expired, otherwise on the function that schedules the worker. The timeout detection can be done by checking if the caller is still waiting for completion or not by using completion_done() function.

[ Upstream commit e7f3187 ] Recently, when running './test_progs -j', I occasionally hit the following errors: test_lwt_redirect:PASS:pthread_create 0 nsec test_lwt_redirect_run:FAIL:netns_create unexpected error: 256 (errno 0) torvalds#142/2 lwt_redirect/lwt_redirect_normal_nomac:FAIL torvalds#142 lwt_redirect:FAIL test_lwt_reroute:PASS:pthread_create 0 nsec test_lwt_reroute_run:FAIL:netns_create unexpected error: 256 (errno 0) test_lwt_reroute:PASS:pthread_join 0 nsec torvalds#143/2 lwt_reroute/lwt_reroute_qdisc_dropped:FAIL torvalds#143 lwt_reroute:FAIL The netns_create() definition looks like below: #define NETNS "ns_lwt" static inline int netns_create(void) { return system("ip netns add " NETNS); } One possibility is that both lwt_redirect and lwt_reroute create netns with the same name "ns_lwt" which may cause conflict. I tried the following example: $ sudo ip netns add abc $ echo $? 0 $ sudo ip netns add abc Cannot create namespace file "/var/run/netns/abc": File exists $ echo $? 1 $ The return code for above netns_create() is 256. The internet search suggests that the return value for 'ip netns add ns_lwt' is 1, which matches the above 'sudo ip netns add abc' example. This patch tried to use different netns names for two tests to avoid 'ip netns add <name>' failure. I ran './test_progs -j' 10 times and all succeeded with lwt_redirect/lwt_reroute tests.

Hi,
This patch series is intended to:
the fan of a few new models.
fiddling around with the step-wise governor has been a very fragile thing
in the past and as it broke again, I used the opportunity to add a two
point thermal governor which implements the actual fan handling required by
acerhdf and puts from my point of view things straight.
char by u8 (Patch 6)
Thanks and kind regards,
peter
