2020-07-02xen/xenbus: let xenbus_map_ring_valloc() return errno values onlyJuergen Gross1-16/+6
Today xenbus_map_ring_valloc() can return either a negative errno value (-ENOMEM or -EINVAL) or a grant status value. This is a mess as e.g -ENOMEM and GNTST_eagain have the same numeric value. Fix that by turning all grant mapping errors into -ENOENT. This is no problem as all callers of xenbus_map_ring_valloc() only use the return value to print an error message, and in case of mapping errors the grant status value has already been printed by __xenbus_map_ring() before.

2020-07-02xen/xenbus: avoid large structs and arrays on the stackJuergen Gross1-78/+83
xenbus_map_ring_valloc() and its sub-functions are putting quite large structs and arrays on the stack. This is problematic at runtime, but might also result in build failures (e.g. with clang due to the option -Werror,-Wframe-larger-than=... used). Fix that by moving most of the data from the stack into a dynamically allocated struct. Performance is no issue here, as xenbus_map_ring_valloc() is used only when adding a new PV device to a backend driver. While at it move some duplicated code from pv/hvm specific mapping functions to the single caller.

2020-07-02tpm_tis_spi: Prefer async probeDouglas Anderson1-0/+1
On a Chromebook I'm working on I noticed a big (~1 second) delay during bootup where nothing was happening. Right around this big delay there were messages about the TPM: [ 2.311352] tpm_tis_spi spi0.0: TPM ready IRQ confirmed on attempt 2 [ 3.332790] tpm_tis_spi spi0.0: Cr50 firmware version: ... I put a few printouts in and saw that tpm_tis_spi_init() (specifically tpm_chip_register() in that function) was taking the lion's share of this time, though ~115 ms of the time was in cr50_print_fw_version(). Let's make a one-line change to prefer async probe for tpm_tis_spi. There's no reason we need to block other drivers from probing while we load. NOTES: * It's possible that other hardware runs through the init sequence faster than Cr50 and this isn't such a big problem for them. However, even if they are faster they are still doing _some_ transfers over a SPI bus so this should benefit everyone even if to a lesser extent. * It's possible that there are extra delays in the code that could be optimized out. I didn't dig since once I enabled async probe they no longer impacted me.

2020-07-02tpm: ibmvtpm: Wait for ready buffer before probing for TPM2 attributesDavid Gibson1-7/+7
The tpm2_get_cc_attrs_tbl() call will result in TPM commands being issued, which will need the use of the internal command/response buffer. But, we're issuing this *before* we've waited to make sure that buffer is allocated. This can result in intermittent failures to probe if the hypervisor / TPM implementation doesn't respond quickly enough. I find it fails almost every time with an 8 vcpu guest under KVM with software emulated TPM. To fix it, just move the tpm2_get_cc_attrs_tlb() call after the existing code to wait for initialization, which will ensure the buffer is allocated.

2020-07-02tpm_tis_spi: Don't send anything during flow controlDouglas Anderson1-5/+4
During flow control we are just reading from the TPM, yet our spi_xfer has the tx_buf and rx_buf both non-NULL which means we're requesting a full duplex transfer. SPI is always somewhat of a full duplex protocol anyway and in theory the other side shouldn't really be looking at what we're sending it during flow control, but it's still a bit ugly to be sending some "random" data when we shouldn't. The default tpm_tis_spi_flow_control() tries to address this by setting 'phy->iobuf[0] = 0'. This partially avoids the problem of sending "random" data, but since our tx_buf and rx_buf both point to the same place I believe there is the potential of us sending the TPM's previous byte back to it if we hit the retry loop. Another flow control implementation, cr50_spi_flow_control(), doesn't address this at all. Let's clean this up and just make the tx_buf NULL before we call flow_control(). Not only does this ensure that we're not sending any "random" bytes but it also possibly could make the SPI controller behave in a slightly more optimal way. NOTE: no actual observed problems are fixed by this patch--it's was just made based on code inspection.

2020-07-02tpm: Fix TIS locality timeout problemsJames Bottomley1-10/+9
It has been reported that some TIS based TPMs are giving unexpected errors when using the O_NONBLOCK path of the TPM device. The problem is that some TPMs don't like it when you get and then relinquish a locality (as the tpm_try_get_ops()/tpm_put_ops() pair does) without sending a command. This currently happens all the time in the O_NONBLOCK write path. Fix this by moving the tpm_try_get_ops() further down the code to after the O_NONBLOCK determination is made. This is safe because the priv->buffer_mutex still protects the priv state being modified.

One cleanup - It removes dev_err() call on platform_get_irq() failure because platform_get_irq() call dev_err() itself on failure.

2020-06-30drm/amd/display: Only revalidate bandwidth on medium and fast updatesNicholas Kazlauskas1-4/+6
[Why] Changes that are fast don't require updating DLG parameters making this call unnecessary. Considering this is an expensive call it should not be done on every flip. DML touches clocks, p-state support, DLG params and a few other DC internal flags and these aren't expected during fast. A hang has been reported with this change when called on every flip which suggests that modifying these fields is not recommended behavior on fast updates. [How] Guard the validation to only happen if update type isn't FAST.

2020-06-30drm: sun4i: hdmi: Remove extra HPD pollingChen-Yu Tsai1-3/+2
The HPD sense mechanism in Allwinner's old HDMI encoder hardware is more or less an input-only GPIO. Other GPIO-based HPD implementations directly return the current state, instead of polling for a specific state and returning the other if that times out. Remove the I/O polling from sun4i_hdmi_connector_detect() and directly return a known state based on the current reading. This also gets rid of excessive CPU usage by kworker as reported on Stack Exchange [1] and Armbian forums [2].

2020-06-29Drivers: hv: Change flag to write log level in panic msg to falseJoseph Salisbury1-1/+1
When the kernel panics, one page of kmsg data may be collected and sent to Hyper-V to aid in diagnosing the failure. The collected kmsg data typically contains 50 to 100 lines, each of which has a log level prefix that isn't very useful from a diagnostic standpoint. So tell kmsg_dump_get_buffer() to not include the log level, enabling more information that *is* useful to fit in the page. Requesting in stable kernels, since many kernels running in production are stable releases.

2020-06-29thermal/drivers/rcar_gen3: Fix undefined temperature if negativeDien Pham1-1/+1
As description for DIV_ROUND_CLOSEST in file include/linux/kernel.h. "Result is undefined for negative divisors if the dividend variable type is unsigned and for negative dividends if the divisor variable type is unsigned." In current code, the FIXPT_DIV uses DIV_ROUND_CLOSEST but has not checked sign of divisor before using. It makes undefined temperature value in case the value is negative. This patch fixes to satisfy DIV_ROUND_CLOSEST description and fix bug too. Note that the variable name "reg" is not good because it should be the same type as rcar_gen3_thermal_read(). However, it's better to rename the "reg" in a further patch as cleanup.
