(My patchwork script doesn't support cover letters, yet, so I need to reply to
the first patch)
I was supposed to do a quick 15 minute review, but I got overboard and used
over an hour for this :) But anyway, below are my comments. Mostly looks good
but some work still to do.
+#ifndef HOST_INT_H
Add WILC prefix?
+struct assoc_resp {
+ __le16 capab_info;
+ __le16 status_code;
+ __le16 aid;
+} __packed;
use struct ieee80211_mgmt?
+ //extract RSN capabilities
No C++ style comments, please.
+ wid_list[1].val = (s8 *)&auth_type;
A little bit too much of casting, like in this example, for my taste
but I guess it's not that a bit of problem. Didn't investigate why
this particular cast was need, but I think Johannes already commented
how odd this wid_list looks like. And why sometimes it's (s8 *) and
others (u8 *)?
+ case 'S':
Isn't a proper define much more readable and as a bonus it would
document the meaning of this value? For example, it could
WILC_RESPONSE_TYPE_SCAN or whatever it means. Oh, and the same for
'R', 'I' and others.
do {
....
} while (1);
I see quite a lot of these unconditonal loops in the driver:
wilc_netdev.c:157: while (1) {
wilc_wlan.c:532: } while (1);
wilc_wlan.c:602: } while (1);
wilc_wlan.c:730: } while (1);
wilc_wlan.c:753: } while (1);
wilc_wlan.c:1002: } while (1);
wilc_wlan.c:1009: } while (1);
wilc_wlan_cfg.c:151: } while (1);
wilc_wlan_cfg.c:167: } while (1);
wilc_wlan_cfg.c:183: } while (1);
wilc_wlan_cfg.c:198: } while (1);
wilc_wlan_cfg.c:230: } while (1);
wilc_wlan_cfg.c:303: } while (1);
wilc_wlan_cfg.c:315: } while
(1);
wilc_wlan_cfg.c:327: } while (1);
wilc_wlan_cfg.c:346: } while (1);
This is not recommended in kernel code because a small bug can cause a
never ending loop in kernel. Put some kind of limit to the loop,
either counter or time based, for example:
count = 0;
do {
....
} while (count++ < 100);
Or even some of the while loops could be replaced with for loop, like
the one in wilc_wlan_parse_info_frame().
+ u8 type = (id >> 12) & 0xf;
No magic values, please. My recommendation is to use GENMASK() and
friends, maybe u16_get_bits()?
I also see identical magic values elsewhere, which should be a strong
indication that this needs to be implemented with a proper define.
+int wilc_wlan_cfg_get_wid(u8 *frame, u32 offset, u16 id)
+{
+ u8 *buf;
+
+ if ((offset + 2) >= WILC_MAX_CFG_FRAME_SIZE)
+ return 0;
+
+ buf = &frame[offset];
+
+ buf[0] = (u8)id;
+ buf[1] = (u8)(id >> 8);
In general a struct is MUCH better than manually playing with bytes
using 'u8 buf[]', but I think Johannes told you already that. Here you
could just have a simple '__le16 id' and you could assign to it with
cpu_to_le16(id), a lot cleaner than what's above.
+ /*call host interface info parse as well*/
A space after '/*' and before '*/'. Have you run checkpatch? It should
catch these simple style issues? And you can run with --file directly
on the source tree. Not of course all checkpatch warnings need to be
fixed, but obvious ones like this for sure.
+#define GET_PKT_OFFSET(a) (((a) >> 22) & 0x1ff)
GENMASK() & co
+/*Parameters needed for host interface for remaining on channel*/
checkpatch
+ struct wilc_vif *vif[WILC_NUM_CONCURRENT_IFC];
+ /*protect vif list*/
+ struct mutex vif_mutex;
I would add a newline before the comment, that would make wilc_wfi_netdevice.h
a lot more readable. But that's a style issue and up to you.
+ if (ch_list_attr_idx) {
+ u8 limit = ch_list_attr_idx + 3 + buf[ch_list_attr_idx + 1];
+
+ for (i = ch_list_attr_idx + 3; i < limit; i++) {
+ if (buf[i] == 0x51) {
+ for (j = i + 2; j < ((i + 2) +
buf[i + 1]); j++)
+ buf[j] = sta_ch;
+ break;
+ }
+ }
+ }
No magic values like 0x51, please. And I think this loop needs a
comment what's happening. But I suspect that if you had proper structs
(and not this ugly buf[] stuff) the code would be self-explanatory and
there would be no need for comments.
+ if (op_ch_attr_idx) {
+ buf[op_ch_attr_idx + 6] = 0x51;
+ buf[op_ch_attr_idx + 7] = sta_ch;
+ }
Ditto. And even more of that in wilc_wfi_cfgoperations.c.
+static struct net_device *get_if_handler(struct wilc *wilc, u8
*mac_header)
+{
+ u8 *bssid, *bssid1;
+ int i = 0;
+ struct net_device *ndev = NULL;
+
+ bssid = mac_header + 10;
+ bssid1 = mac_header + 4;
And here a proper struct for mac_header would be so much cleaner.
+static u8 crc7(u8 crc, const u8 *buffer, u32 len)
+{
+ while (len--)
+ crc = crc7_byte(crc, *buffer++);
+ return crc;
+}
What's wrong with <linux/crc7.h>? Why reinvent the wheel?
I see so much this u8 buf[] stuff that I'll stop commenting about it
now. But, for example, spi_cmd_complete() would be a lot cleaner with
proper structs and some refactoring (one function per command or
something like that).
+ if (addr < 0x30) {
Proper defines for magic values, please. This was even used multiple
times.
+ wilc->hif_func->hif_read_reg(wilc, 0xf0, ®);
+
+ wilc->hif_func->hif_write_reg(wilc, 0xf0, reg & ~BIT(0));
+ wilc->hif_func->hif_write_reg(wilc, 0xfa, 0);
Magic values. I'll also stop commenting about magic values, I think you got
the point already :)

This kind of configuration should happen on runtime, not compile time.
In other words, the same kernel module should work on _all_ hardware
without recompilation.
+ reg = (BIT(0) | BIT(1) | BIT(2) | BIT(3) | BIT(8) | BIT(9) | BIT(26) |

I said I would stop commenting about magic values, but here I really
have to comment about it :)
Device tree bindings were not visible. And CC
devicetree@vger.kernel.org as we need an ack from the DT maintainers. Also
I have understood that they require the bindings in YAML format now,
at least that was the comment I got with ath11k.
Please remove the 'wilc_' prefix from the filenames, the directory
name is already wilc1000 so no need to replicate that. For example, rename
wilc_hif.c to just hif.c.
+config WILC1000_HW_OOB_INTR

I think this should be a runtime setting (see my comment about other
compile time settings), for example a module parameter. Would that
work?

Thanks a lot for the complete and detailed review of the driver.
I am glad to know that state of the driver is *good* and thanks for your acknowledgment. Defiantly, Johannes's review comments helped us to improve the driver.
I will continue to work on your review comments and try to address all of them. Most of the comments are clear but there are few comments which need some more clarification especially related to *wid_List*.

the ieee8022_mgmt struct includes the mac header, but the frame received from the device doesn't have it, hence, we can't use the ieee802211_mgmt struct directly

Agree. Will change to C style.

You are right, different locations using u8* and other s8*. I will check and submit the required changes.
I'm not very clear though on why the current implementation of wid_list is odd, and what's the recommendation to fix it, so I'd appreciate more clarification on that.
The wid_list is an array of struct that holds the wid parameters, which is the configuration data to be sent to the device.
This array of structs is passed to cfg_send_config_pkt, which takes care of formatting a config packet that the device understands, from the wid struct, then sends it to the device. It also takes care of waiting for the response from the device.

Agree. Will change to meaningful macros.

Agree. Will go through the infinite loops and try to limit them.

Agree. Will use macros to define magic values, and GENMASk/u16_get_bits() to parse bit fields

Agree. These changes were already submitted to staging after we received Johannes' feedback to use put_unaligned_le16(), so will be included in v3 of the patch

Agree. Will add spaces as recommended.
Actually we ran checkpatch, but it didn't catch this warning.
Currently the driver has only one warning in wilc_wfi_cfgoperations.c for a line being over 80 chars. not sure why this wasn't caught by the checkpatch script.
I'm using the parameters below to run the script, so please let me know if we should be using something else.

The new implementation of crc7 after commit 1836eea209546b870dd83f3f4ef234d6598a560d uses a different syndrome table than what the WILC SPI uses, and we can't change that since crc7 calculation is in done in the hardware IP.

Sure, will check and refactor spi_cmd_complete().

I see, the device tree binding file is not shown properly in the patch because patch indicate the changes as file movement from "staging" to "Documentation/devicetree/bindings/net/wireless" folder.
We don't have binding in YAML format yet so I will make the changes and sent them to review to devicetree@vger.kernel.org also.

Okay. Will change this to runtime setting using module paramter.

'bool' is a pretty bad idea, there's no storage guarantee for it. Use u8
instead, especially in a firmware struct.
But overall, if I remember correctly, this is a massive improvement,
last time I looked I think you basically had something like
char msg[10];
int i = 0;
msg[i++] = reg;
msg[i++] = reg_id;
msg[i++] = frame_type >> 8;
msg[i++] = (u8)frame_type;
so obviously this is *much* better.
I still think you'd benefit from putting the firmware API structs into a
separate include file so you can differentiate them, but YMMV.

I still find this whole wid_list stuff to be a bit confusing, especially
since it looks like a *firmware* thing but then you have the *host
pointer* inside the value ...
There must be a translation layer somewhere, but I can't help but wonder
if that's really worth the complexity, vs. just building the right thing
directly here (with some helpers perhaps).

The translation to firmware buffer happens in wilc_wlan_cfg_set() and
wilc_wlan_cfg_commit() adds a single *wilc_cfg_cmd_hdr* header before
sending to firmware.
There are two ways to send the wid's from host to firmware.
1/ Single Wid -> In this case, single wid is sent by adding
*wilc_cfg_cmd_hdr* in single command buffer to firmware.
i.e <wilc_cfg_cmd_hdr><wid1>
2/ Mutliple Wid's -> In this case, multiple wid's are clubbled together
and sent in single command buffer.
e.g. <wilc_cfg_cmd_hdr><wid1><wid2><wid3>
As the firmware is design to receive configuration under different
WID's, so it is required from the host side to club these parameters
whenever data is related.
Currently, wilc_send_config_pkt() is provided as helper API to construct
buffer based on passed *wids* and *counts*. This will avoid adding
similar logic in multiple places.

Ajay

There are helpers for that, put_le16_unaligned() or so?

I really don't understand this style. Why not give it a proper struct
and just say
wl->cfg.assoc_rsp = str_vals->assoc_rsp;
etc?

As I see, the data received from the firmware in *le* format, which is
parsed in wilc_wlan_parse_response_frame(). So to extract value in
correct byteorder we should use get_unaligned_le32(). right?

Yes, the comments has not capture about 'S' message type. 'S' type is
used to notify scan completed from firmware to host.

Actually, WID’s are used to send the configuration data from host to
firmware. Its generic approach to manage the different size of wid.
The different WID’s are categorized based on their data size.
Instead of managing different variables for each WID's its kept under
the single array. These entries are managed like 'id' and 'value'.
struct wilc_cfg {
struct wilc_cfg_byte *b;
struct wilc_cfg_hword *hw;
struct wilc_cfg_word *w;
struct wilc_cfg_str *s;
struct wilc_cfg_str_vals *str_vals;
};
The 1-byte data are managed in ‘b’ array, 2-byte in ‘hw’ array and so
on. So whenever the WID is set/get by host, the corresponding value also
get updated in this array which can be access later. The response from
firmware also contains the WID id which is used to udpate the
corresponding value. This categorization helps in search and update the
exact WID value *wilc_cfg* struct.
